Description

本発明は、洋上風力発電の風車設備の設置専用船、設置治具及び設置方法に関するものである。   The present invention relates to a dedicated ship for installation of wind turbine equipment for offshore wind power generation, an installation jig, and an installation method.

洋上風力発電設備は、基本的に風が強い外洋に設置するほうが電力事業としては有利である。しかしながら、風が強いということは、それに伴って気象海象条件も悪くなる。現状の洋上風力発電設備の施工は、気象海象条件の影響を受けやすいので、洋上風力発電設備の設置場所が、電力事業として有利となる風が強い場所であるほど、設置にかかる工期が長くなり、それに伴い洋上風力発電設備の設置費用も膨大なものとなってしまう。   It is more advantageous for the power business to install offshore wind power generation facilities in the open ocean where wind is basically strong. However, the strong winds are accompanied by a worsening weather and sea conditions. Current offshore wind power generation facilities are susceptible to the influence of meteorological conditions, so the longer the wind power that is advantageous to the power business, the longer the installation period. As a result, the installation cost of offshore wind power generation facilities will be enormous.

このため、洋上において気象海象条件に左右されずに、いかに短い工期で洋上風力発電設備を設置できるかが一番の課題であり、従来においては、以下の３つの方法がある。   For this reason, the biggest problem is how to install an offshore wind power generation facility in a short construction period without being influenced by the weather and sea conditions on the ocean. Conventionally, there are the following three methods.

（ａ）自己昇降装置付きの自航式のクレーン船を利用する方法。 (A) A method using a self-propelled crane ship with a self-elevating device.

このクレーン船は、自己昇降装置を有し、この自己昇降装置は、図２５に示すように、例えば、クレーン船１の四隅に鉛直方向に延びる昇降自在に設けた四本の昇降用レグ２と、この各昇降用レグ２を昇降する油圧ジャッキシステム３とからなり、上記油圧ジャッキシステム３を操作することにより、上記昇降用レグ２を下方に降ろして、上記昇降用レグ２を海底４に支持させて、そして、上記クレーン船１を海面上に持ち上げて（水切り）、上記クレーン船１を海面上で固定する。   This crane ship has a self-elevating device, and as shown in FIG. 25, for example, the self-elevating device has four elevating legs 2 provided vertically at the four corners of the crane ship 1 so as to elevate vertically. The hydraulic jack system 3 for raising and lowering each of the lifting legs 2 is operated. By operating the hydraulic jack system 3, the lifting leg 2 is lowered and the lifting leg 2 is supported on the seabed 4. Then, the crane ship 1 is lifted on the sea surface (draining), and the crane ship 1 is fixed on the sea surface.

この方法においては、上記クレーン船１を岸壁につけて、タワーや、発電機等を内蔵するナセルや、ブレードなど、解体した各風車設備部品５を積み込み、この各風車設備部品５を、風力発電設置現場まで運搬する。そして、上記自己昇降装置により、上記クレーン船１をジャッキアップして水切りし、海面上で固定して、上記クレーン船１のクレーン６により、例えば、既に海底４に設置されている風力発電設備の基礎部となるモノパイル７上に、上記風車設備部品５を組み立てて、風車設備８を設置する。   In this method, the crane ship 1 is attached to a quay, and a disassembled wind turbine equipment component 5 such as a tower, a nacelle with a built-in generator, a blade, or the like is loaded, and each wind turbine equipment component 5 is installed in wind power generation. Transport to the site. Then, the crane ship 1 is jacked up and drained by the self-elevating device, fixed on the sea surface, and the crane 6 of the crane ship 1, for example, a wind power generation facility already installed on the seabed 4. The windmill equipment component 5 is assembled on the monopile 7 that is the base, and the windmill equipment 8 is installed.

この方法によれば、上記クレーン船１は海面上で固定されているので、気象海象条件に左右されずに、短い工期で洋上風力発電設備を設置することができる。   According to this method, since the crane ship 1 is fixed on the sea surface, the offshore wind power generation facility can be installed in a short construction period without being affected by the weather conditions.

（ｂ）自己昇降装置付き台船（Ｓｅｌｆ Ｅｌｅｖａｔｉｎｇ Ｐｌａｔｆｏｒｍ：以下「ＳＥＰ台船」と略称する）を使用する方法。 (B) A method of using a self-elevating trolley (Self Elevating Platform: hereinafter abbreviated as “SEP trolley”).

この方法においては、図２６に示すように、風車設備設置用の大型クローラークレーン９を搭載した大型クローラークレーン用ＳＥＰ台船１０と、タワーや、発電機等を内蔵するナセルや、ブレードなど、解体した各風車設備部品５を積んだ資材運搬用ＳＥＰ台船１１とを、風力発電設置現場まで曳航する。そして、昇降用レグ２と油圧ジャッキシステム３とよりなる自己昇降装置により、上記各ＳＥＰ台船１０、１１をジャッキアップして水切りし、海面上で固定して、上記大型クローラークレーン９により、例えば、既に海底４に設置されている風力発電設備の基礎部となるモノパイル７上に、上記風車設備部品５を組み立てて、風車設備８を設置する。   In this method, as shown in FIG. 26, a large crawler crane SEP trolley 10 equipped with a large crawler crane 9 for installing a wind turbine equipment, a tower, a nacelle with a built-in generator, a blade, and the like are dismantled. The material transport SEP trolley 11 loaded with the respective wind turbine equipment parts 5 is towed to the wind power generation installation site. Then, the SEP carriages 10 and 11 are jacked up and drained by a self-elevating device comprising the lifting leg 2 and the hydraulic jack system 3, and fixed on the sea surface. Then, the windmill equipment component 5 is assembled on the monopile 7 that is the foundation of the wind power generation equipment already installed on the seabed 4, and the windmill equipment 8 is installed.

この方法においても、各ＳＥＰ台船１０、１１は海面上で固定されているので、気象海象条件に左右されずに、短い工期で洋上風力発電設備を設置することができる。   Also in this method, since each SEP carrier 10 and 11 is fixed on the sea surface, an offshore wind power generation facility can be installed in a short period of time without being affected by weather conditions.

（ｃ）大型起重機船（フローティングクレーン）を使用して風車設備を一括して設置する方法。 (C) A method of installing wind turbine equipment collectively using a large hoist ship (floating crane).

この方法においては、陸上（岸壁等）で、解体された風車設備部品５を組み立てて、この組み立てられた風車設備８を、大型起重機船１２のクレーン１３にて、特殊治具１４を介して、一括して吊り下げる。そして、図２７に示すように、上記風車設備８をそのまま吊り下げた状態で、上記大型起重機船１２を風力発電設置現場まで曳航する。そして、例えば、既に海底４に設置されている、風力発電設備の基礎部となるジャケット１５の上部に固定した一方の接続部材１６と、上記特殊治具１４の他方の接続部材１７とを接続させて、上記風車設備８が揺れないようにしてから、上記風車設備８を上記ジャケット１５上に一括して設置する。   In this method, the disassembled windmill equipment parts 5 are assembled on land (quay etc.), and the assembled windmill equipment 8 is connected to the crane 13 of the large hoist ship 12 via the special jig 14. Suspend all at once. Then, as shown in FIG. 27, the large hoist ship 12 is towed to the wind power generation installation site with the wind turbine equipment 8 suspended as it is. Then, for example, one connection member 16 fixed to the upper part of the jacket 15 that is already installed on the seabed 4 and serves as the foundation of the wind power generation facility is connected to the other connection member 17 of the special jig 14. Then, after the wind turbine equipment 8 is not shaken, the wind turbine equipment 8 is collectively installed on the jacket 15.

なお、上記特殊治具１４は、図２８に示すように、上記風車設備８のタワー１８の下端部を固定すると共に、上記一方の接続部材１６に接続される他方の接続部材１７と、上記タワー１８の上部分を貫通させて、上記風車設備８を吊り下げた時に、上記風車設備８の傾倒を防止するための環状の上部部材１９と、上記他方の接続部材１７と上記上部部材１９とを連結するワイヤー２０と、上記上部部材１９に設けた、クレーン吊り下げ用の吊下ピース２１とよりなる。   As shown in FIG. 28, the special jig 14 fixes the lower end portion of the tower 18 of the wind turbine equipment 8 and also connects the other connection member 17 connected to the one connection member 16 and the tower. An annular upper member 19 for preventing the wind turbine equipment 8 from being tilted when the wind turbine equipment 8 is suspended through the upper portion of 18, the other connecting member 17, and the upper member 19. It consists of a wire 20 to be connected and a hanging piece 21 for hanging a crane provided on the upper member 19.

この方法においては、風力発電設置現場において、風車設備を組み立てる必要がないので、短い工期で洋上風力発電設備を設置することができる。   In this method, since it is not necessary to assemble the wind turbine equipment at the wind power generation installation site, the offshore wind power generation equipment can be installed in a short construction period.

上記従来の自己昇降装置付きの船を用いて風車設備を設置する方法としては、例えば、特許文献１、特許文献２がある。   As a method for installing wind turbine equipment using the above-described conventional ship with a self-elevating device, for example, there are Patent Document 1 and Patent Document 2.

特開２００４−１７５０号公報JP 2004-1750 A 特開２００６−３７３９７号公報JP 2006-37397 A

しかしながら、上記従来の方法（ａ）は、現地で風車設備を組み立てながら設置するので、外洋での作業日数が多くなる。そのため、洋上風力発電設備の設置費用も膨大なものとなってしまう。   However, since the conventional method (a) is installed while assembling the wind turbine equipment locally, the number of work days in the open ocean increases. For this reason, the installation cost of the offshore wind power generation facilities will be enormous.

また、従来の方法（ｂ）も、現地で風車設備を組み立てながら設置するので、外洋での作業日数が多くなる。そのため、洋上風力発電設備の設置費用も膨大なものとなってしまう。   Moreover, since the conventional method (b) is also installed while assembling the wind turbine equipment locally, the number of work days in the open ocean increases. For this reason, the installation cost of the offshore wind power generation facilities will be enormous.

また、ＳＥＰ台船の大きさから、風車設備１基分しか現地へ運搬できない。そのため１基設置するごとに帰港し、風車設備部品を運搬しなければならない。   Also, because of the size of the SEP trolley, only one windmill facility can be transported to the site. Therefore, every time one unit is installed, it must return to the port and carry wind turbine equipment parts.

また、上記従来の方法（ｃ）は、自己昇降装置がないので、気象海象条件が極めて良好で安定している時でないと施工できない。   Further, since the conventional method (c) does not have a self-elevating device, it cannot be constructed unless the weather and sea conditions are very good and stable.

また、風力発電設備の基礎部となるジャケット１５の上部の一方の接続部材１６に、上記特殊治具１４の他方の接続部材１７とを接続させた後、上記風車設備８を上記ジャケット１５上に固定するまでの間、船の揺れに伴う上記特殊治具１４の揺れを吸収するために、上記他方の接続部材１７と上部部材１９とはワイヤーにより接続する必要がある。このワイヤー接続のため、特殊治具１４のセッティング時と解体時の作業が複雑になる。   In addition, after connecting the other connecting member 17 of the special jig 14 to one connecting member 16 on the upper part of the jacket 15 which is the foundation of the wind power generation facility, the windmill facility 8 is placed on the jacket 15. Until the fixing, the other connecting member 17 and the upper member 19 need to be connected by a wire in order to absorb the shaking of the special jig 14 accompanying the shaking of the ship. This wire connection complicates the work of setting and disassembling the special jig 14.

また、洋上風力発電設備の基礎部上に一方の接続部材１６を取付ける必要があるが、モノパイルのように上端に一方の接続部材１６を設置スペースがない場合には、この方法を用いることができない。   Moreover, although it is necessary to attach one connection member 16 on the foundation part of an offshore wind power generation equipment, when there is no installation space for one connection member 16 at the upper end like a monopile, this method cannot be used. .

また、１基しか吊り下げることができないので、設置効率が悪い。   Moreover, since only one can be suspended, installation efficiency is poor.

本発明は上記の欠点を除くようにしたものである。   The present invention eliminates the above-mentioned drawbacks.
