Abstract

This floating offshore facility (1) is configured such that: the propulsion system for moving the floating offshore facility (1) is configured by an electric propulsion system (20) which uses electric motors (22a and 22b) to drive a propeller (21); a first group of electric generators (11a, 11b, 12a, and 12b) is arranged on the upper deck (3), while a second group of electric generators (13a and 13b) is arranged in an engine room (5); and electric power for running production equipment (30) on the floating offshore facility (1) is supplied by both the first and second groups, while electric power for driving the electric motors (22a and 22b) is supplied by the second group. This configuration significantly reduces the space taken up by the engine room (5) where the propulsion system, which is used when navigating to an offshore site for installation but is otherwise unnecessary in operation on the sea, is arranged, and thereby significantly increases the space that can be used by the offshore production equipment (30) and by a hold (6) for storage.

Description

浮体式洋上設備、及び、浮体式洋上設備の電力供給方法Floating offshore facility and power supply method for floating offshore facility
　本発明は、浮体式洋上設備、及び、浮体式洋上設備の電力供給方法に関し、より詳細には、上甲板の上の発電装置を配設するためのスペースを大幅に減少することができて、洋上設備としての生産や貯蔵のための設備のスペースを著しく増大することができる、浮体式洋上設備、及び、浮体式洋上設備の電力供給方法に関する。 The present invention relates to a floating offshore facility and a power supply method for a floating offshore facility, and more specifically, a space for installing a power generation device on an upper deck can be greatly reduced, The present invention relates to a floating offshore facility and a method of supplying power to the floating offshore facility, which can significantly increase the space for production and storage as an offshore facility.
　石油・ガスの生産設備を備え、長期間に亘って特定の洋上設置場所に位置保持されて使用されるＦＰＳＯ（浮体式生産貯蔵積出設備）、石油・ガスの生産設備を持たないＦＳＯ（浮体式貯蔵積出設備）やＦＳＵ（浮体式貯蔵設備）、ＬＮＧを扱うＦＬＮＧ（液化貯蔵積出設備）等の浮体式洋上設備は、洋上で係留や自動位置保持装置等により位置保持しながら、浮かんだ状態で、生産活動及び生産物の一時的貯蔵を行っている。 FPSO (floating production storage and loading equipment) equipped with oil and gas production facilities and kept at a specific offshore installation location for a long period of time, FSO (floating bodies) without oil and gas production facilities Floating offshore facilities such as floating storage and loading facilities), FSU (floating storage facilities), and FLNG (liquefied storage and loading facilities) that handle LNG float while being held in place by mooring or automatic position holding devices, etc. In this state, production activities and products are temporarily stored.
　これらの浮体式洋上設備の建造は、既存のＶＬＣＣ（大型タンカー）を改造して建造することが主流であるが、最近は、新造で浮体式洋上設備を建造するケースがでてきており、この新造のケースにおいてもＶＬＣＣの設計をベースに設計され、建造されている。 The construction of these floating offshore facilities is mainly done by remodeling existing VLCCs (large tankers), but recently there have been cases where new offshore facilities have been built. Even new cases are designed and built based on the VLCC design.
　この浮体式洋上設備を建造するにあたり、新造船では、自らの移送手段を持たせない場合には、生産現場まで曳航するか、重量運搬船により移送する必要が生じる。従って、長距離の移動が生じる場合には、例えば、浮体式洋上設備をアジアで建造して、ブラジルで設置する場合等では、初期移送費用が非常に高くつくことになってしまう。 In constructing this floating offshore facility, if a new ship does not have its own means of transportation, it will be necessary to tow to the production site or transport it by a heavy transport ship. Therefore, when long-distance movement occurs, for example, when a floating offshore facility is constructed in Asia and installed in Brazil, the initial transfer cost is very high.
　そのため、推進システムを、ＶＬＣＣと同様にする場合は、図７に示すように、機関室５Ｘの大半を、ディーゼルエンジンが多用される主機関４０等の推進機関関連の機器と航行時に必要な電力を発生させるための２基～３基程度のディーゼル発電装置４１等が占めているが、この推進機能及び航行時用の発電装置４１は、製造所又は港から油田までの移動の際しか用いられず、浮体式洋上設備１Ｘの稼働中は必要とされない。そのため、生産設備３０の稼働中は使用されない推進機関関連の機器類や発電装置４１で、機関室５Ｘのスペース（斜線のハッチング部分）が大きく取られるため、上甲板より下に配設される生産物の貯蔵用の貨物倉６のスペースが小さくなり、上甲板３より下の部分の有効利用がなされていないという問題がある。 Therefore, when the propulsion system is made the same as that of the VLCC, as shown in FIG. 7, most of the engine room 5X is made up of propulsion engine-related equipment such as the main engine 40 where diesel engines are frequently used and power required for navigation. 2 to 3 diesel generators 41, etc. for generating power are occupied, but the propulsion function and the power generator 41 for navigation are used only when moving from the factory or the port to the oil field. It is not required during operation of the floating offshore facility 1X. Therefore, because the space (shaded hatched portion) of the engine room 5X is large in the propulsion engine-related equipment and the power generation device 41 that are not used while the production facility 30 is in operation, the production arranged below the upper deck There is a problem that the space of the cargo hold 6 for storing goods is reduced, and the portion below the upper deck 3 is not effectively used.
　また、この浮体式洋上設備１Ｘにおいては、上甲板３の上に生産設備３０とこの生産設備３０を駆動するための例えば発電装置３１からなる発電装置群が配設されている。この発電装置群は設置面積がディーゼル発電機に比べて小さくて済むガスタービン発電機を２基～８基程度（図７では３基×横２列の６基）を上甲板３に配設することで形成されている。そのため、生産設備３０を配設するスペースが小さくなるという問題がある。 In the floating offshore facility 1X, a power generation device group including a production facility 30 and, for example, a power generation device 31 for driving the production facility 30 is disposed on the upper deck 3. In this power generator group, about 2 to 8 gas turbine generators (3 in FIG. 7 × 6 in 2 horizontal rows) are installed on the upper deck 3 which requires a smaller installation area than a diesel generator. It is formed by that. Therefore, there exists a problem that the space which arrange | positions the production equipment 30 becomes small.
　更に、生産設備の電力発生用には、上甲板の上の発電装置が占めるスペースを小さくするために使用するスペースが比較的小さいガスタービン発電機が用いられているが、このガスタービン発電機のエネルギー効率が、背が高く使用するスペースが比較的大きいディーゼル発電機のエネルギー効率より悪く、燃費及び省エネルギーの面から改善の余地があるという問題もある。 Furthermore, a gas turbine generator that uses a relatively small space to reduce the space occupied by the power generation device on the upper deck is used for power generation in production facilities. There is also a problem that the energy efficiency is worse than that of a diesel generator that is tall and uses a relatively large space, and there is room for improvement in terms of fuel consumption and energy saving.
　一方、船舶の推進システムとして、例えば、日本出願の特開２０１３－４３４８５号公報に記載されているように、内燃機関により直接、推進器のプロペラを回転駆動する代わりに、発電機で発電した電気を電動機に供給し、この電動機で推進用プロペラを駆動する電気推進船が開発され、この電気推進船において、複数の発電機と、推進用電動機と発電機を接続する低周波数回路と、低周波数回路に周波数及び電圧変換器を介して接続した通常回路を有し、発電機で発電する交流電流の周波数が、５０Ｈｚより小さくなるように制御することで、機関室内の容積効率を向上し、且つ、航行の際の燃費効率を向上させる電気推進船が提案されている。 On the other hand, as a ship propulsion system, for example, as described in Japanese Patent Application Laid-Open No. 2013-43485, instead of directly driving a propeller of a propulsion device directly by an internal combustion engine, An electric propulsion ship has been developed to drive a propeller for propulsion with this electric motor. In this electric propulsion ship, a plurality of generators, a low frequency circuit for connecting the propulsion motor and the generator, and a low frequency By having a normal circuit connected to the circuit via a frequency and voltage converter and controlling the frequency of the alternating current generated by the generator to be lower than 50 Hz, the volume efficiency in the engine room is improved, and An electric propulsion ship that improves fuel efficiency during navigation has been proposed.
　また、例えば、日本出願の特表２００７－５０４０４５号公報に記載されているように、発電機及び推進モータを実質的に同じ動作特性を有する永久磁石型同期機で形成し、これらの同期機を固定的な電気接続によって互いに直結することにより、プロペラの回転速度を、パワーエレクトロニクスの使用なしで変化させて、ギヤなしで減じることができて、投資及び空間の要件を減らすことができる船及び可動海洋構造物の推進システムも提案されている。 Further, for example, as described in Japanese Patent Application Publication No. 2007-504045, a generator and a propulsion motor are formed of a permanent magnet type synchronous machine having substantially the same operating characteristics, and these synchronous machines are By connecting directly with fixed electrical connection, the speed and speed of propeller can be changed without the use of power electronics, and can be reduced without gear, reducing the investment and space requirements Offshore structure propulsion systems have also been proposed.
　しかしながら、これらの電気推進船や船及び可動海洋構造物の推進システムでは、浮体式洋上設備における上甲板の上に配置される発電装置群のスペースの問題については何らの言及もなされていない。 However, in these propulsion systems for electric propulsion vessels, ships, and movable offshore structures, no mention is made of the problem of the space of the power generators arranged on the upper deck in the floating offshore facilities.

　本発明者らは、上記の状況を鑑みて、生産設備の稼働時に推進機能が不要となる浮体式洋上設備に対して、従来のディーゼルエンジン等主機関で推進器を駆動する推進システムよりも機関室を小さくできる電気推進システムと、生産設備の稼働用の発電装置群とを組み合わせることにより、機関室を小さくして、貨物倉の増大を図ると共に、甲板上に配設される発電装置群の一部を電気推進システムと兼用すると共に、兼用する発電装置を機関室内に配設することで、上甲板の上に配設される発電装置群のスペースを減少でき、生産設備のスペースを増加できるとの知見を得た。 In view of the above situation, the present inventors have considered an engine rather than a propulsion system that drives a propulsion unit with a main engine such as a conventional diesel engine for a floating offshore facility that does not require a propulsion function when the production facility is in operation. By combining an electric propulsion system that can reduce the size of a room with a group of power generation devices for operating production facilities, the engine room can be made smaller, the cargo hold can be increased, and the power generation device group installed on the deck A part of the power generation system can be shared with the electric propulsion system, and the power generation equipment that is also used in the engine room can reduce the space for the power generation equipment group arranged on the upper deck and increase the space for production equipment. And gained knowledge.
　本発明の目的は、浮体式洋上設備において製造所や港から洋上設置場所までの航海では使用するが、洋上で稼働しているときには不要となる推進システムを配設する機関室のスペースを大幅に減少することができて、洋上設備としての生産設備や貯蔵のための貨物倉のスペースを著しく増大することができる浮体式洋上設備、及び、浮体式洋上設備の電力供給方法を提供することにある。 The purpose of the present invention is to use a floating offshore facility for a voyage from a factory or a port to a place where it is installed offshore. An object of the present invention is to provide a floating offshore facility that can be reduced and can significantly increase the space for production facilities and storage for cargo storage as an offshore facility, and a power supply method for the floating offshore facility. .
　上記のような目的を達成するための本発明の浮体式洋上設備は、複数の発電装置によって電力が供給される生産設備を備えて、洋上に位置保持されて使用される浮体式洋上設備において、当該浮体式洋上設備を移動するための推進システムを電動機で推進器を駆動する電気推進システムで構成すると共に、第１グループの前記発電装置を上甲板上に、第２グループの前記発電装置を機関室内にそれぞれ配置して構成し、かつ、当該浮体式洋上設備に設けた生産設備を稼働する電力を前記第１グループと第２グループの両方の前記発電装置により供給すると共に、前記電動機を駆動する電力を前記第２グループの前記発電装置により供給するように構成される。 The floating offshore facility of the present invention for achieving the above object comprises a production facility to which power is supplied by a plurality of power generators, and the floating offshore facility is used while being held on the ocean. The propulsion system for moving the floating offshore facility is composed of an electric propulsion system that drives a propulsion device with an electric motor, and the first group of the power generation devices are arranged on the upper deck, and the second group of the power generation devices is an engine. The electric power for operating the production facility provided in the floating offshore facility is supplied by the power generators of both the first group and the second group, and the motor is driven. Power is configured to be supplied by the power generators of the second group.
　この構成によれば、発電装置群の第２グループを機関室内に設けても、浮体式洋上設備を移動するための推進システムを電動機で推進器を駆動する電気推進システムで構成することにより、内燃機関による推進器を直接駆動する推進システムを採用する場合よりも機関室全体のスペースを小さくすることができ、上甲板の下に配設される貨物倉のスペースを大きくとることができるようになる。 According to this configuration, even if the second group of the power generation device group is provided in the engine room, the propulsion system for moving the floating offshore facility is configured by the electric propulsion system that drives the propulsion device with the electric motor, thereby The space of the entire engine room can be made smaller than when a propulsion system that directly drives the propulsion unit by the engine is adopted, and the space of the cargo hold disposed below the upper deck can be increased. .
　また、生産設備に電力を供給する発電装置群の第２グループを機関室に設けることにより、上甲板の上の発電装置群の第１グループの発電装置の基数を減少することができるので、大幅に、上甲板の上の発電装置群が占めるスペースを小さくすることができ、生産設備用のスペースを増大することができる。 In addition, by providing the engine room with the second group of power generators that supply power to the production facility, the number of power generators of the first group of power generators on the upper deck can be reduced. In addition, the space occupied by the power generation device group on the upper deck can be reduced, and the space for production equipment can be increased.
　更に、浮体式生産設備の建造場所から設置場所までの航行に一時的に必要な、電気推進装置、推進制御装置、航海設備等の初期移動装置を設けて航行するので初期移動費用を抑えることが可能になる。その上、この航行に一時的に必要な電力を、生産設備の稼働時に使用する発電装置群の第２グループの発電装置で発電するので、航行時のみに使用する発電装置を設ける必要がなくなる。特に、浮体式生産設備が、１００ＭＷクラスの大規模発電システムを備える場合には、航行時に電気推進システムで使用する電力を十分賄うことができる。 Furthermore, since initial navigation devices such as electric propulsion devices, propulsion control devices, and navigation facilities that are temporarily required for navigation from the construction site to the installation site of floating production facilities are installed, navigation costs can be reduced. It becomes possible. In addition, since the power necessary for the navigation is generated by the power generation device of the second group of the power generation device group used when the production facility is in operation, it is not necessary to provide a power generation device that is used only during the navigation. In particular, when the floating production facility includes a large-scale power generation system of 100 MW class, it is possible to sufficiently cover the electric power used by the electric propulsion system during navigation.
　従って、従来技術で上甲板の上に装備されていた大規模発電システムの一部を機関室内に装備するため、生産設備を設置する上甲板の上のスペースをより広く利用できる。また、初期移動装置の投資費用を抑え、自航費用を低減できる。 Therefore, since a part of the large-scale power generation system equipped on the upper deck in the prior art is installed in the engine room, the space above the upper deck where the production equipment is installed can be used more widely. In addition, the investment cost of the initial mobile device can be suppressed, and the self-navigation cost can be reduced.
　なお、電力供給の制御の面から考えると、発電装置を同一機種、同一容量にするのが好ましく、発電装置の基数の配置に関しては、第１グループを４基とし、第２グループを２基とするのが、航行時の電力消費の面から好ましい。 In terms of power supply control, it is preferable to use the same type of generator and the same capacity as the generator. Regarding the arrangement of the radix of the generator, the first group is four and the second group is two. This is preferable from the viewpoint of power consumption during navigation.
　また、上甲板の上に配置される第１グループの発電装置の一部又は全部を使用して、航行時に電気推進システムで使用する電力を供給することも考えられるが、浮体式生産設備の建造工程を考えた場合に、機関室内に電気推進システムと第２グループの発電装置が配置された後に、上甲板の上の第１グループの発電装置が配置される場合があり、必ずしも、航行時に第１グループの発電装置が設置及び稼働可能になっているとは限らないので、第２グループの発電装置で電気推進システムに電力供給することが好ましい。 It is also conceivable to use part or all of the first group of power generators arranged on the upper deck to supply the electric power used by the electric propulsion system during navigation. Considering the process, after the electric propulsion system and the second group of power generators are arranged in the engine room, the first group of power generators on the upper deck may be arranged. Since it is not always possible to install and operate one group of power generators, it is preferable to supply power to the electric propulsion system with the second group of power generators.
　また、本発明は、言い換えれば、上甲板上に配置される生産設備のスペース確保のために、同じく上甲板上に配設される発電装置群のスペースをできるだけ小さくすることが好ましいので、本発明者らは、熟慮の上で、発電装置群を２つのグループに分けて、一方の第２グループの発電装置を機関室内に移動すると共に、この機関室内への発電装置の移動に伴って、機関室のスペースが増大すると、今度は、上甲板の下の貨物倉のスペースが減少するので、電気推進システムとの組み合わせにより、機関室のスペースの減少を図ると共に、電気推進システムの発電装置の部分を第２グループの発電装置で代用することにより、機関室内の機器構成を簡素化すると共に、更に、機関室のスペースを減少して、貨物倉のスペースを拡大するものである。 In addition, the present invention, in other words, it is preferable to make the space of the power generation device group disposed on the upper deck as small as possible in order to secure the space for the production equipment disposed on the upper deck. With careful consideration, the power generator group is divided into two groups, one of the second group of power generators is moved into the engine room, and the engine is moved along with the movement of the power generator into the engine room. If the space in the room increases, the space in the cargo hold below the upper deck will decrease, so the combination with the electric propulsion system will reduce the space in the engine room and By substituting the power generation device of the second group, the equipment configuration in the engine room is simplified, and further, the space in the engine room is reduced and the space in the cargo hold is expanded. A.
　上記の浮体式洋上設備において、前記発電装置の少なくとも一部または全部をディーゼル発電機で構成すると、機関室内においては、電気推進システムを採用した場合でも、推進器軸や電動機や発電装置や推進制御装置等を配置するスペースを確保する必要があり、この電気推進システム用のスペースは、内燃機関で直接推進器を回転駆動する推進システムを採用する場合よりも小さいスペースになるため、ディーゼル発電機を配設できるスペースを容易に確保できるので、ガスタービン発電機を採用する場合よりも、燃費を向上することができる。 In the above floating offshore facility, if at least a part or all of the power generator is configured with a diesel generator, the propulsion shaft, the motor, the power generator, the propulsion control, and the like in the engine room even when the electric propulsion system is adopted. It is necessary to secure a space for arranging the devices, etc., and the space for this electric propulsion system is smaller than the case where a propulsion system that directly rotates the propulsion unit is used in an internal combustion engine. Since the space which can be arrange | positioned can be ensured easily, a fuel consumption can be improved rather than the case where a gas turbine generator is employ | adopted.
　上記の浮体式洋上設備において、前記電気推進システムの推進器の回転数制御をインバータで行うと共に、該インバータを貨物ポンプの移送速度制御にも使用する構成とすると、高価なインバータを、初期移動と生産物の移送に利用できるので、効率よくインバータを使用でき、全体としての設備コストを低減できる。つまり、従来技術では貨物ポンプはボイラで発生する蒸気で駆動するように形成されているが、初期移動で使用するインバータがある場合には、このインバータを兼用またはインバータの配置換えにより、初期移動と生産設備の稼働の両方で使用することで低コストのまま貨物ポンプを電気駆動に切り替えることができる。この貨物ポンプの電動化を採用することにより、従来技術の蒸気タービン駆動の貨物ポンプに比べて、燃料費の低減に寄与することができる。 In the above floating offshore facility, when the rotational speed control of the propulsion unit of the electric propulsion system is performed by an inverter and the inverter is also used for the transfer speed control of the cargo pump, the expensive inverter is replaced with the initial movement. Since it can be used for transferring products, the inverter can be used efficiently, and the overall equipment cost can be reduced. In other words, in the prior art, the cargo pump is configured to be driven by steam generated in the boiler. However, if there is an inverter used for initial movement, this inverter can be used as an initial movement or by switching the inverter. The cargo pump can be switched to electric drive at low cost by using it for both operation of production facilities. By adopting the electrification of this cargo pump, it is possible to contribute to a reduction in fuel costs as compared to the conventional steam turbine driven cargo pump.
　そして、上記の目的を達成するための浮体式洋上設備の電力供給方法は、複数の発電装置によって電力が供給される生産設備を備えて、洋上に位置保持されて使用される浮体式洋上設備の電力供給方法において、当該浮体式洋上設備に設けた生産設備を稼働する電力を上甲板上に配設した第１グループの前記発電装置と機関室内に配設した第２グループの前記発電装置により供給すると共に、当該浮体式洋上設備を移動するための電気推進システムの電動機を駆動する電力を前記第２グループの前記発電装置により供給することを特徴とする方法である。 And the electric power supply method of the floating offshore facility for achieving the above-mentioned object comprises a production facility to which electric power is supplied by a plurality of power generators, and the floating offshore facility to be used while being held on the ocean. In the power supply method, the electric power for operating the production facility provided in the floating offshore facility is supplied by the first group of power generators disposed on the upper deck and the second group of power generators disposed in the engine room. The electric power for driving the electric motor of the electric propulsion system for moving the floating offshore facility is supplied by the power generator of the second group.
　この方法によれば、上甲板の上の生産設備への電力供給を上甲板上の第１グループの発電装置群と機関室内に装備された第２グループの発電装置群で行うので、上甲板の上に配設する発電装置の基数を少なくすることができ、生産設備を設置する上甲板をより広く利用できる。また、初期移動時は、第２グループの発電装置群で電気推進システムの電動機に電力供給するため、初期移動装置のための投資費用を抑え、自航費用を低減できる。 According to this method, the power supply to the production equipment on the upper deck is performed by the first group of generators on the upper deck and the second group of generators installed in the engine room. It is possible to reduce the number of power generators arranged on the top, and to use the upper deck on which production equipment is installed more widely. In addition, during the initial movement, power is supplied to the motor of the electric propulsion system by the second group of power generation devices, so that the investment cost for the initial movement device can be suppressed and the self-propulsion cost can be reduced.
　本発明の浮体式洋上設備、及び、浮体式洋上設備の電力供給方法によれば、製造所や港から洋上設置場所までの航海で使用する推進システムを電気推進システムで構成することにより、推進システムを配設する機関室のスペースを大幅に減少することができ、上甲板の下に配設される貨物倉のスペースを大きくとることができるようになる。 According to the floating offshore facility and the power supply method for the floating offshore facility according to the present invention, the propulsion system used in the voyage from the manufacturing site or the port to the offshore installation location is constituted by an electric propulsion system. It is possible to greatly reduce the space of the engine room in which the vehicle is disposed, and it is possible to increase the space of the cargo hold disposed below the upper deck.
　また、第２グループの発電装置を機関室に設けることにより、上甲板の上に配置される第１グループの発電装置の基数を減少できるので、上甲板の上の発電装置群が占めるスペースを大幅に減少することができ、生産設備用のスペースを増大することができる。 In addition, by providing the second group of power generators in the engine room, the number of the first group of power generators arranged on the upper deck can be reduced, greatly increasing the space occupied by the group of power generators on the upper deck. The space for production equipment can be increased.
　更に、浮体式生産設備の建造場所から設置場所までの航行に一時的に必要な電力を、生産設備の稼働時に使用する発電装置群の一部である第２グループの発電装置で発電するので、航行時のみに使用する発電装置を別に設ける必要がなくなる。 Furthermore, since the electric power temporarily required for navigation from the construction site to the installation site of the floating production facility is generated by the second group of power generation devices that are part of the power generation device group used when the production facility is in operation, There is no need to provide a separate power generator for use only during navigation.
　従って、従来技術で上甲板の上に装備されていた大規模発電システムの一部を機関室内に装備するため、生産設備を設置する上甲板の上のスペースをより広く利用できる。また、初期移動装置の投資費用を抑え、自航費用を低減できる。 Therefore, since a part of the large-scale power generation system equipped on the upper deck in the prior art is installed in the engine room, the space above the upper deck where the production equipment is installed can be used more widely. In addition, the investment cost of the initial mobile device can be suppressed, and the self-navigation cost can be reduced.

　以下、本発明に係る実施の形態の浮体式洋上設備、及び、浮体式洋上設備の電力供給方法について、図面を参照しながら説明する。この実施の形態の浮体式洋上設備として、ＦＰＳＯ（浮体式生産貯蔵積出設備）を例にして説明するが、本発明は、このＦＰＳＯに限定する必要はなく、洋上を航行するときに推進装置を必要とし、洋上で稼働中は推進装置を必要としない浮体式洋上設備であれば、適用することができる。 Hereinafter, a floating offshore facility according to an embodiment of the present invention and a power supply method for the floating offshore facility will be described with reference to the drawings. As the floating offshore facility of this embodiment, an FPSO (floating body production storage and loading facility) will be described as an example. However, the present invention is not limited to this FPSO, and the propulsion device is used when navigating offshore. If it is a floating offshore facility that does not require a propulsion device during operation on the ocean, it can be applied.
　例えば、石油・ガスの生産設備を持たないＦＳＯ（浮体式貯蔵積出設備）やＦＳＵ（浮体式貯蔵設備）、ＬＮＧを扱うＦＬＮＧ（液化貯蔵積出設備：ＬＮＧ-ＦＰＳＯ）、ＬＰＧを扱うＦＬＰＧ（ＬＰＧ-ＦＰＳＯ）、ＦＳＲＵ（浮体式貯蔵再ガス化設備）等にも本発明を適用することができる。 For example, FSO (floating storage and loading equipment) and FSU (floating storage equipment) without oil and gas production facilities, FLNG (liquefied storage and loading equipment: LNG-FPSO) that handles LNG, FLPG that handles LPG ( The present invention can also be applied to LPG-FPSO), FSRU (floating body storage regasification facility), and the like.
　なお、一般的に、ＦＰＳＯ等の浮体式洋上設備１は、ＶＬＣＣ等の船舶とほぼ同様の形状をしていることが多いので、ここでは、各部の名称もＶＬＣＣ等の船舶に準じて「船体」「船尾」「上甲板」などの呼称を用いて説明する。 In general, the floating offshore facility 1 such as FPSO has almost the same shape as a vessel such as VLCC, so here, the names of the respective parts are the same as those of the vessel such as VLCC. ”,“ Stern ”,“ upper deck ”, etc.
　図１～図５に示すように、この実施の形態の浮体式洋上設備１は、ＶＬＣＣ等の船舶と略同様な形状をしており、製造所又は港から油田等のある洋上設置場所に自航で移動し、係留システムや自動位置保持システムにより、この洋上設置場所で洋上に位置保持している状態で使用される。 As shown in FIGS. 1 to 5, the floating offshore facility 1 of this embodiment has substantially the same shape as a vessel such as a VLCC, and is automatically installed from a manufacturing site or port to an offshore installation site such as an oil field. It moves by voyage and is used in a state where it is held on the ocean at this offshore installation location by a mooring system or automatic position holding system.
　図１に示すように、この浮体式洋上設備１は、船体２と上甲板３と船尾部４を有し、この船尾部４の前の上甲板３の下に機関室５を、この機関室５の前方に貨物倉６を、機関室５の上に居住区や航行時の船橋となる部分からなる上部構造物７を、それぞれ設けている。また、機関室５の上方部位には煙突５ａが設けられている。なお、浮体式洋上設備１が一時的にせよ自航する場合には上部構造物７の船橋に航海設備を装備して、初期移動用に利用する。 As shown in FIG. 1, this floating offshore facility 1 has a hull 2, an upper deck 3, and a stern part 4, and an engine room 5 is provided under the upper deck 3 in front of the stern part 4. A cargo hold 6 is provided in front of 5, and an upper structure 7 composed of a residential area and a portion serving as a bridge during navigation is provided on the engine room 5. A chimney 5 a is provided in the upper part of the engine room 5. In addition, when the floating offshore facility 1 is to be self-propelled even temporarily, a navigation facility is installed on the bridge of the superstructure 7 and used for initial movement.
　また、図２に示すように、この上部構造物７の前方の上甲板３の上に、例えば、原油または天然ガスを処理する生産設備３０とこの生産設備３０に電力を供給する発電装置群の第１グループの発電装置１１ａ、１１ｂ、１２ａ、１２ｂが配置されている。通常、この第１グループの発電装置１１ａ、１１ｂ、１２ａ、１２ｂは、生産設備３０よりも上部構造物７側、即ち、後方側に配置され、横に２列に設けられる。 Further, as shown in FIG. 2, on the upper deck 3 in front of the superstructure 7, for example, a production facility 30 for processing crude oil or natural gas and a power generator group for supplying power to the production facility 30. A first group of power generators 11a, 11b, 12a, and 12b are arranged. Normally, the power generators 11a, 11b, 12a, and 12b of the first group are arranged on the upper structure 7 side, that is, the rear side with respect to the production facility 30, and are provided in two rows horizontally.
　そして、図３～図５に示すように、この浮体式洋上設備１は、船体２の船尾部４側に電気推進システム２０を備えて構成され、この電気推進システム２０は、機関室５の船尾部４側に突き出したプロペラ回転軸（推進軸）２１ａの後端に取り付けられたプロペラ（推進器）２１と、機関室５内に電動機（推進モータ）２２ａ、２２ｂと発電装置群の第２グループの発電装置１３ａ、１３ｂが、それぞれ横２列に配置されて設けられている。 As shown in FIGS. 3 to 5, the floating offshore facility 1 includes an electric propulsion system 20 on the stern portion 4 side of the hull 2, and the electric propulsion system 20 includes the stern of the engine room 5. The propeller (propulsion unit) 21 attached to the rear end of the propeller rotation shaft (propulsion shaft) 21a protruding toward the section 4 side, the motors (propulsion motors) 22a and 22b in the engine room 5, and the second group of power generators The power generators 13a and 13b are arranged in two horizontal rows.
　つまり、この浮体式洋上設備１は、複数（この実施の形態では６基）の発電装置１１ａ、１１ｂ、１２ａ、１２ｂ、１３ａ、１３ｂによって電力が供給される生産設備３０を備えて、洋上に位置保持されて使用される浮体式洋上設備１であり、この浮体式洋上設備１を移動するための推進システムを電動機２２ａ、２２ｂでプロペラ２１を駆動する電気推進システム２０で構成する。それと共に、第１グループの発電装置１１ａ、１１ｂ、１２ａ、１２ｂを上甲板３上に、第２グループの発電装置１３ａ、１３ｂを機関室５内にそれぞれ配置して構成する。 That is, the floating offshore facility 1 includes a production facility 30 to which power is supplied by a plurality (six in this embodiment) of power generation devices 11a, 11b, 12a, 12b, 13a, and 13b. A floating offshore facility 1 that is held and used, and a propulsion system for moving the floating offshore facility 1 includes an electric propulsion system 20 that drives a propeller 21 with electric motors 22a and 22b. At the same time, the first group of power generation devices 11a, 11b, 12a, and 12b are arranged on the upper deck 3, and the second group of power generation devices 13a and 13b are arranged in the engine room 5, respectively.
　更に、この浮体式洋上設備１に設けた生産設備３０を稼働する電力を第１グループと第２グループの両方の発電装置１１ａ、１１ｂ、１２ａ、１２ｂ、１３ａ、１３ｂにより供給すると共に、電動機２２ａ、２２ｂを駆動する電力を第２グループの発電装置１３ａ、１３ｂにより供給するように構成する。 Further, the electric power for operating the production facility 30 provided in the floating offshore facility 1 is supplied by the power generators 11a, 11b, 12a, 12b, 13a, 13b of both the first group and the second group, and the electric motor 22a, The power for driving 22b is supplied by the second group of power generation devices 13a and 13b.
　この場合に、電力供給の制御の面から考えると、発電装置１１ａ、１１ｂ、１２ａ、１２ｂ、１３ａ、１３ｂを同一機種、同一容量にするのが好ましく、発電装置１１ａ、１１ｂ、１２ａ、１２ｂ、１３ａ、１３ｂの基数の配置に関しては、第１グループの発電装置１１ａ、１１ｂ、１２ａ、１２ｂを４基とし、第２グループの発電装置１３ａ、１３ｂを２基とするのが、航行時の電力消費の面から好ましい。 In this case, from the viewpoint of control of power supply, it is preferable that the power generation devices 11a, 11b, 12a, 12b, 13a, and 13b have the same model and capacity, and the power generation devices 11a, 11b, 12a, 12b, and 13a. , 13b, the first group of power generation devices 11a, 11b, 12a, 12b and the second group of power generation devices 13a, 13b are two units. From the aspect, it is preferable.
　また、発電装置１１ａ、１１ｂ、１２ａ、１２ｂ、１３ａ、１３ｂの少なくとも一部または全部をディーゼル発電機で構成すると、機関室５内においては、電気推進システム２０を採用した場合でも、プロペラ回転軸２１ａや電動機２２ａ、２２ｂや発電装置１３ａ、１３ｂや推進制御装置（図示しない）等を配置するスペースを確保する必要があり、この電気推進システム２０用のスペースは、内燃機関で直接推進器を回転駆動する推進システムを採用する場合よりも小さいスペースになるため、ディーゼル発電機を配設できるスペースを容易に確保できるので、ガスタービン発電機を採用する場合よりも、燃費を向上することができる。 Further, if at least a part or all of the power generators 11a, 11b, 12a, 12b, 13a, and 13b are configured by a diesel generator, the propeller rotary shaft 21a is provided in the engine room 5 even when the electric propulsion system 20 is employed. Space for electric motors 22a and 22b, power generators 13a and 13b, a propulsion control device (not shown), etc. must be secured, and the space for this electric propulsion system 20 is directly driven by the internal combustion engine to drive the propeller. Since the space becomes smaller than the case where the propulsion system is employed, the space where the diesel generator can be disposed can be easily secured, so that the fuel consumption can be improved as compared with the case where the gas turbine generator is employed.
　上記の構成によれば、浮体式洋上設備１を移動するための推進システムを電動機２２ａ、２２ｂでプロペラ２１を駆動する電気推進システム２０で構成しているので、発電装置群の第２グループの発電装置１３ａ、１３ｂを機関室５内に設けても、図７に示す従来技術のように内燃機関で構成される主機関４０によるプロペラ２１を直接駆動する推進システムを採用する場合よりも機関室５全体のスペースを小さくすることができ、上甲板３の下に配設される貨物倉６のスペースを大きくとることができる。 According to the above configuration, the propulsion system for moving the floating offshore facility 1 is configured by the electric propulsion system 20 that drives the propeller 21 with the electric motors 22a and 22b. Even if the devices 13a and 13b are provided in the engine room 5, the engine room 5 is more than the case where a propulsion system that directly drives the propeller 21 by the main engine 40 constituted by an internal combustion engine as in the prior art shown in FIG. The entire space can be reduced, and the space of the cargo hold 6 disposed under the upper deck 3 can be increased.
　また、生産設備３０に電力を供給する発電装置群の第２グループの発電装置１３ａ、１３ｂを機関室５に設けることにより、上甲板３の上の発電装置群の第１グループの発電装置１１ａ、１１ｂ、１２ａ、１２ｂの基数を、この実施の形態では６基から４基に減少することができるので、大幅に、上甲板３の上の発電装置群が占めるスペースを小さくすることができ、生産設備３０用のスペースを増大することができる。 Further, by providing the engine room 5 with the second group of power generation devices 13a and 13b of the power generation device group that supplies power to the production facility 30, the first group of power generation devices 11a on the upper deck 3, Since the number of bases 11b, 12a and 12b can be reduced from 6 to 4 in this embodiment, the space occupied by the power generator group on the upper deck 3 can be greatly reduced, The space for the facility 30 can be increased.
　更に、浮体式生産設備１の建造場所から設置場所までの航行に一時的に必要な、電気推進装置、推進制御装置、航海設備等の初期移動装置を設けて航行するので初期移動費用を抑えることが可能になる。その上、この航行に一時的に必要な電力を、生産設備３０の稼働時に使用する発電装置群の第２グループの発電装置１３ａ、１３ｂで発電するので、航行時のみに使用する発電装置を設ける必要がなくなる。特に、浮体式生産設備１が、１００ＭＷクラスの大規模発電システムを備える場合には、航行時に電気推進システム２０で使用する電力を十分賄うことができる。 In addition, since initial navigation devices such as electric propulsion devices, propulsion control devices, and navigation facilities that are temporarily required for navigation from the construction site to the installation location of the floating production facility 1 are provided, navigation costs are reduced. Is possible. In addition, since the power necessary for the navigation is generated by the power generation devices 13a and 13b of the second group of the power generation device group that is used when the production facility 30 is in operation, a power generation device that is used only during the navigation is provided. There is no need. In particular, when the floating production facility 1 includes a large-scale power generation system of 100 MW class, it is possible to sufficiently cover the power used by the electric propulsion system 20 during navigation.
　また、図６に示すように、電気推進システム２０のプロペラ２１の回転数制御をインバータ２５ａ、２５ｂで行うと共に、このインバータ２５ａ、２５ｂを貨物ポンプ（図示しない）の移送速度制御にも使用する構成とすると、高価なインバータ２５ａ、２５ｂを、浮体式生産設備１の初期移動と生産物の移送に利用できるので、効率よくインバータ２５ａ、２５ｂを使用でき、全体としての設備コストを低減できる。つまり、従来技術では貨物ポンプは蒸気駆動で形成されているが、初期移動で使用するインバータ２５ａ、２５ｂがある場合には、このインバータ２５ａ、２５ｂを兼用またはインバータ２５ａ、２５ｂの配置換えにより、初期移動と生産設備３０の稼働の両方で使用することで低コストのまま貨物ポンプを電気駆動に切り替えることができる。この貨物ポンプの電動化を採用することにより、従来技術の蒸気タービン駆動の貨物ポンプに比べて、燃料費の低減に寄与することができる。 Further, as shown in FIG. 6, the rotation speed control of the propeller 21 of the electric propulsion system 20 is performed by the inverters 25a and 25b, and the inverters 25a and 25b are also used for the transfer speed control of the cargo pump (not shown). Then, since the expensive inverters 25a and 25b can be used for the initial movement of the floating production facility 1 and the transfer of the product, the inverters 25a and 25b can be used efficiently, and the equipment cost as a whole can be reduced. That is, in the prior art, the cargo pump is formed by steam drive, but when there are inverters 25a and 25b used for the initial movement, the inverters 25a and 25b can be used together or by rearranging the inverters 25a and 25b. By using it for both movement and operation of the production facility 30, the freight pump can be switched to electric drive with low cost. By adopting the electrification of this cargo pump, it is possible to contribute to a reduction in fuel costs as compared to the conventional steam turbine driven cargo pump.
　従って、従来技術で上甲板３の上に装備されていた大規模発電システムの一部を機関室５内に装備するため、生産設備３０を設置する上甲板３の上のスペースをより広く利用できる。また、初期移動装置の投資費用を抑え、自航費用を低減できる。 Therefore, since a part of the large-scale power generation system equipped on the upper deck 3 in the prior art is installed in the engine room 5, the space above the upper deck 3 on which the production equipment 30 is installed can be used more widely. . In addition, the investment cost of the initial mobile device can be suppressed, and the self-navigation cost can be reduced.
　そして、本発明の実施の形態の浮体式洋上設備の電力供給方法は、図６に示すように、複数の発電装置１１ａ、１１ｂ、１２ａ、１２ｂ、１３ａ、１３ｂによって電力が供給される生産設備３０を備えて、洋上に位置保持されて使用される浮体式洋上設備１の電力供給方法であり、この浮体式洋上設備１に設けた生産設備３０を稼働する電力を上甲板３の上に配設した第１グループの発電装置１１ａ、１１ｂ、１２ａ、１２ｂと機関室５内に配設した第２グループの発電装置１３ａ、１３ｂにより供給すると共に、この浮体式洋上設備１を移動するための電気推進システム２０の電動機２２ａ、２２ｂを駆動する電力を第２グループの発電装置１３ａ、１３ｂにより供給する方法である。 And the electric power supply method of the floating type offshore installation of embodiment of this invention is the production equipment 30 with which electric power is supplied by several electric power generation apparatus 11a, 11b, 12a, 12b, 13a, 13b, as shown in FIG. Is a method for supplying power to the floating offshore facility 1 that is used while being held on the ocean. The power for operating the production facility 30 provided on the floating offshore facility 1 is disposed on the upper deck 3. Electricity propulsion for moving the floating offshore facility 1 while being supplied by the first group of power generators 11a, 11b, 12a, 12b and the second group of power generators 13a, 13b disposed in the engine room 5 In this method, electric power for driving the electric motors 22a and 22b of the system 20 is supplied by the second group of power generation devices 13a and 13b.
　より具体的には、図６の上の部分に示すように、浮体式洋上設備１の稼働時は、上甲板３の上の第１のグループの発電装置１１ａ、１１ｂ、１２ａ、１２ｂで発電された電力は、上甲板３サイドの１３．８ｋＶまたは１１ｋＶスイッチボード２３ａでまとめられ、変圧器２６ａに入り、１３．８ｋＶまたは１１ｋＶから６．６ｋＶ／４４０Ｖに変換されて、６．６ｋＶ／４４０Ｖスイッチボード２７ａに供給され、この６．６ｋＶ／４４０Ｖスイッチボード２７ａから、生産設備３０の電力消費部分に供給される。 More specifically, as shown in the upper part of FIG. 6, when the floating offshore facility 1 is in operation, power is generated by the first group of power generators 11 a, 11 b, 12 a, 12 b on the upper deck 3. The power is collected by the 13.8kV or 11kV switch board 23a on the upper deck 3 side, enters the transformer 26a, is converted from 13.8kV or 11kV to 6.6kV / 440V, and then becomes the 6.6kV / 440V switch board. 27a, and is supplied from the 6.6kV / 440V switch board 27a to the power consumption portion of the production facility 30.
　また、図６の下の部分に示すように、機関室５内の第２のグループの発電装置１３ａ、１３ｂで発電された電力は、浮体式洋上設備１の自航時は、変圧器２４ａ、２４ｂで電動機２２ａ、２２ｂの使用電圧に変換され、インバータ２５ａ、２５ｂを経由して電動機２２ａ、２２ｂに供給され、電動機２２ａ、２２ｂの回転はギヤ装置２８により、プロペラ回転軸２１ａの回転に変換されて、プロペラ２１の回転となり、このプロペラ２１の回転により浮体式洋上設備１は推進力を得て自航することができる。なお、プロペラ２１の回転数制御は、インバータ２５ａ、２５ｂによって行われる。 In addition, as shown in the lower part of FIG. 6, the electric power generated by the second group of power generation devices 13 a and 13 b in the engine room 5 is converted into a transformer 24 a and a self-propulsion by the floating offshore facility 1. 24b is converted into a working voltage of the electric motors 22a and 22b, supplied to the electric motors 22a and 22b via the inverters 25a and 25b, and the rotation of the electric motors 22a and 22b is converted into the rotation of the propeller rotary shaft 21a by the gear device 28. Thus, the propeller 21 is rotated, and the floating offshore facility 1 is able to travel by obtaining propulsion by the rotation of the propeller 21. The rotation speed control of the propeller 21 is performed by the inverters 25a and 25b.
　また、浮体式洋上設備１の稼働時は、機関室５内の第２のグループの発電装置１３ａ、１３ｂで発電された電力は、機関室５サイドの１３．８ｋＶまたは１１ｋＶスイッチボード２３ｂでまとめられ、変圧器２６ｂに入り、１３．８ｋＶまたは１１ｋＶから６．６ｋＶ／４４０Ｖに変換されて、６．６ｋＶ／４４０Ｖスイッチボード２７ｂに供給され、この６．６ｋＶ／４４０Ｖスイッチボード２７ｂから、生産設備３０の電力消費部分に供給される。 When the floating offshore facility 1 is in operation, the electric power generated by the second group of power generation devices 13a and 13b in the engine room 5 is collected by the 13.8 kV or 11 kV switch board 23b on the engine room 5 side. , Enters the transformer 26b, is converted from 13.8kV or 11kV to 6.6kV / 440V, and is supplied to the 6.6kV / 440V switch board 27b, from which the 6.6kV / 440V switch board 27b Supplied to the power consumption part.
　なお、この図６の実施の形態では、プロペラ２１の推進力を変化させるためにプロペラ回転数制御をインバータ２５ａ、２５ｂで行っているが、プロペラ２１を可変ピッチプロペラ（ＣＰＰ）で構成し、電動機２２ａ、２２ｂを誘導型モータで構成した場合には、プロペラ２１のピッチ（迎角）を変化させることで、プロペラ２１の推進力を変化させることができる。この構成では、高価なインバータ２５ａ、２５ｂを使用しなくて済むが、貨物ポンプを電動化してインバータを使用する場合は、このインバータをプロペラ２１の回転数制御用のインバータ２５ａ、２５ｂとして用いることが好ましい。 In the embodiment shown in FIG. 6, the propeller rotational speed control is performed by the inverters 25a and 25b in order to change the propulsion force of the propeller 21, but the propeller 21 is configured by a variable pitch propeller (CPP), and the electric motor When 22a and 22b are comprised with the induction type motor, the propulsive force of the propeller 21 can be changed by changing the pitch (attack angle) of the propeller 21. FIG. In this configuration, it is not necessary to use expensive inverters 25a and 25b. However, when an inverter is used by electrifying the cargo pump, this inverter may be used as the inverters 25a and 25b for controlling the rotation speed of the propeller 21. preferable.
　この方法によれば、上甲板の上の生産設備への電力供給を上甲板上の第１グループの発電装置群と機関室内に装備された第２グループの発電装置群で行うので、上甲板の上に配設する発電装置の基数を少なくすることができ、生産設備を設置する上甲板をより広く利用できる。また、初期移動時は、第２グループの発電装置群で電気推進システムの電動機に電力供給するため、初期移動装置のための投資費用を抑え、自航費用を低減できる。 According to this method, the power supply to the production equipment on the upper deck is performed by the first group of generators on the upper deck and the second group of generators installed in the engine room. It is possible to reduce the number of power generators arranged on the top, and to use the upper deck on which production equipment is installed more widely. In addition, during the initial movement, power is supplied to the motor of the electric propulsion system by the second group of power generation devices, so that the investment cost for the initial movement device can be suppressed and the self-propulsion cost can be reduced.
　従って、上記の構成の浮体式洋上設備１、及び、浮体式洋上設備の電力供給方法によれば、製造所や港から洋上設置場所までの航海で使用する推進システムを電気推進システム２０で構成することにより、推進システムを配設する機関室のスペースを大幅に減少することができ、上甲板３の下に配設される貨物倉６のスペースを大きくとることができるようになる。例えば、図１に示すハッチング（斜線）部分を貨物倉６のスペースとして使用できるようになる。 Therefore, according to the floating offshore facility 1 configured as described above and the power supply method for the floating offshore facility, the electric propulsion system 20 constitutes the propulsion system used in the voyage from the factory or the port to the offshore installation location. As a result, the space in the engine room in which the propulsion system is disposed can be greatly reduced, and the space in the cargo hold 6 disposed under the upper deck 3 can be increased. For example, the hatched portion shown in FIG. 1 can be used as a space for the cargo hold 6.
　また、第２グループの発電装置１３ａ、１３ｂを機関室５に設けることにより、上甲板３の上に配置される第１グループの発電装置１１ａ、１１ｂ、１２ａ、１２ｂの基数を減少できるので、上甲板３の上の発電装置群が占めるスペースを大幅に減少することができ、生産設備３０用のスペースを増大することができる。 Further, by providing the second group of power generation devices 13a, 13b in the engine room 5, the number of the first group of power generation devices 11a, 11b, 12a, 12b arranged on the upper deck 3 can be reduced. The space occupied by the power generation device group on the deck 3 can be greatly reduced, and the space for the production facility 30 can be increased.
　更に、浮体式生産設備１の建造場所から設置場所までの航行に一時的に必要な電力を、生産設備３０の稼働時に使用する発電装置群の一部である第２グループの発電装置１３ａ、１３ｂで発電するので、航行時のみに使用する発電装置を別に設ける必要がなくなる。 Furthermore, the second group of power generation devices 13 a and 13 b that are part of the power generation device group that uses temporarily the power necessary for navigation from the construction site to the installation location of the floating production facility 1 when the production facility 30 is in operation. Therefore, it is not necessary to provide a separate power generator for use only during navigation.
　従って、従来技術で上甲板３の上に装備されていた大規模発電システムの一部を機関室５内に装備するため、生産設備３０を設置する上甲板３をより広く利用できる。また、初期移動装置の投資費用を抑え、自航費用を低減できる。 Therefore, since a part of the large-scale power generation system equipped on the upper deck 3 in the prior art is installed in the engine room 5, the upper deck 3 on which the production equipment 30 is installed can be used more widely. In addition, the investment cost of the initial mobile device can be suppressed, and the self-navigation cost can be reduced.
　本発明の浮体式洋上設備、及び、浮体式洋上設備の電力供給方法によれば、浮体式洋上設備において製造所や港から洋上設置場所までの航海では使用するが、洋上で稼働しているときには不要となる推進システムを配設する機関室のスペースを大幅に減少することができて、洋上設備としての生産設備や貯蔵のための貨物倉のスペースを著しく増大することができるので、多くの浮体式洋上設備に利用することができる。 According to the floating offshore facility and the power supply method of the floating offshore facility according to the present invention, the floating offshore facility is used in a voyage from a factory or a port to an offshore installation location. Since the space in the engine room where the unnecessary propulsion system is installed can be greatly reduced, the production facilities as offshore facilities and the cargo hold space for storage can be remarkably increased. It can be used for offshore facilities.
