Background technology
The development of offshore drilling and production technology makes petroleum industry have the ability to produce in the zones of different in the world, and wherein, these zones comprise deepwater environment and do not have explored underwater production fields in the past.Along with this class is produced, how people are concerned about with transportation of petroleum products station ashore.Traditional transportation resources comprises adopts large-scale sea bed petroleum pipeline or natural gas line, these pipelines will be from different oil carriers, production platform, perhaps the product of similar device (they may be associated with one or more different oil fields under water) mixes, to be transported to a central station on the bank, perhaps be stored in a center delivery site.Being accompanied by the difficulty that this class pipeline or main line (trunklines) produced is so simple situation: the product that has different qualities must " mix " in pipeline.Such mixing usually is undesirable, particularly under the situation that the operator wishes their product and other products separated, perhaps under not wishing to pay because their product can not satisfy some standard the situation of the additional expenses of taxation or other expense, the operator do not wish such mixing.For example, a kind of high-quality when oily when a special exploiting field or field produces, the operator may not wish this high-quality oil is mixed with various more inferior oil.Say that in some sense such mixing has watered down high-quality oil, and may damage the market potential price of higher quality oil.
Often be accompanied by and the another kind of problem that will pay close attention to occurred with the relevant natural gas that Petroleum Production is produced together.Usually be difficult to sell economically these natural gases.Production unit may attempt these natural gases are burnt; Yet, provide against or greatly limit such burning in many countries or area.It is another kind of replacement scheme that gas is refilled, but opportunity cost is very expensive.Therefore, production vessel, production platform or similar facility are transported to the selling spot with relevant natural gas by the sea bed conveying route, and typically, a seabed trunklines is used for natural gas, and a seabed trunklines is used for oil.In order to be transported to such gas trunklines, natural pressure need be reduced to a sufficiently high pressure.Since low flow rate cause mobile assurance may make that with operation problem the processing cost of relevant natural gas is higher than the sales value of natural gas.The cost of investment that such system and pipeline are installed may be suppressed by cost, and this comprises in order to make relevant natural gas reach the cost of investment and the running cost of the gas compressor of natural gas pipeline pressure hope or that require.
The other problem that is accompanied by the use generation of such conveying route comprises the position in a special exploiting field.For example, when beginning to produce in a new exploiting field, particularly underwater continental shelf or the transition region that obviously increases of the degree of depth under water, neighbouring may not have the sea bed conveying route.Therefore, for production vessel or platform are connected on such seabed trunklines, must lay connecting line.Depend on related distance, the laying of pipeline may become and suppressed by cost, makes the exploitation in these oil fields become uneconomical.And problem becomes and worsens more under the environment of deep water production.The increase of water depth typically improves the cost of the cost/unit length of institute's pipeline installation, and increase demand for bigger pipeline, so that satisfy so higher production requirement in deep water oil field, thereby proof is because the so higher harsh economic restriction that cost of investment and running cost produced of deep water oil field requirement of exploitation is rational.
Other problem comprises the difficulty that pipeline is installed, and these difficulties may appear in the pipeline that unfavorable environment lays, for example uneven or sea bed that tilts, and the sea bed that has cave and valley.
The problem that will pay close attention in addition comprises with the operator uses these pipelines or the relevant cost issues of main line.In other words, the operator is in order ashore to pay " transport cost " with their Product transport.Almost always to pay additional pipeline transportation expense for oil being transported to desirable delivery site.

The specific embodiment
Though show a kind of exemplary embodiment of the present invention in beginning below just should be appreciated that,, can adopt the technology of any kind of, whether known or whether existed no matter these technology are current, realize the present invention.The present invention should be not limited to illustrative embodiments, accompanying drawing that illustrates below and the technology that illustrates below fully, is included in the exemplary designs and the embodiment that illustrate and describe here.In addition, the accompanying drawing that is comprised here not necessarily proportionally draws.
Fig. 1-4 generally illustrates a kind of process and system that can be used for collecting and selling the treated hydrocarbon that comprises exploiting field, deep water oil field in the exploiting field, various hydrocarbons oil field of being managed free various oil company.Although will understand with reference to exemplary structural configuration of such process prescription, such operation is not limited to this class configuration with being understood that.Can adopt other configuration, not only comprise those configurations of now having known, and those configurations that will develop after comprising.
In the offshore production of hydrocarbon, a production unit (or equipment) is platform for example, and the hydrocarbon that is obtained by one or more hydrocarbons oil field/exploiting field generally can be produced and/or store to float (or floating on the surface) production system or oil carrier (kinetics ground location or grappling) or similar facilities.Having had multiple technologies, facility and configuration extracts (or exploitation), stores and process these hydrocarbons.Here the process of Miao Shuing is not limited to any in these technology, but wishes to be used for any extraction and treatment technology/configuration, no matter these techniques/configurations be now known or will develop in the future.By themselves platform or unsteady production vessel (semi-submersible type, masts type in boat form, or the like) on any operator processing of carrying out hydrocarbon may obtain some interests, this includes but not limited to guarantee can be satisfied by all products that a specific operator's facility is exported some operator's index (for example, the content of water content and other impurity).After such production, can will be transported to a unsteady petroleum storage that the gas utilization ability arranged through (do) crude oil of handling and (doing) relevant natural gas transportation (for example adopting pump or similar device) and unload on the oil carrier (FSOG oil carrier) 50.
Because the oil from specific oil field, exploiting field or operator has specific quality or feature (for example an operator may select a specific oil field owing to its feature), may wish to transport individually and sell such oil, that is, keep these oil to be separated from each other from each oil field, exploiting field or operator.For this reason, the oil and natural gas from a specific exploiting field can be transported to FSOG oil carrier 50 in independent pipeline.Fig. 1 shows a such example, shows from exploiting field A the independently oil and natural gas pipeline of B and D.Although can adopt multiple different device that the independence transportation from the product of storage/production facility is become easily,, for simplicity, only show the transport line of extending by these exploiting fields.Therefore, understand with being understood that, can adopt any transportation technology, or now known, or developing in the future.Although shown pipeline by three independently exploiting field A, B and D extend,, independently pipeline also can be extended by identical exploiting field (for example exploiting field A), in this case, generally exists a kind of hope, promptly product is remained in the independent pipeline.In such configuration, it should be recognized by those skilled in the art that to exist the single structure that to put two or more independent line.Although what illustrated is different independent line, but be to be understood that, some pipeline in these pipelines can be with from other oil field or operator's product (for example, or product in operator's pipeline or the product in operator's facility) blended product.To a certain extent, the degree that will keep requirement that product separates and/or operator's preferential selection decision that these different products are separated according to hope.More details about the interests of separating will be described below in more detail.
Fig. 1 show on sea bed by oil and natural gas pipeline A, the Product transport that the end points of B and D (being the exploiting field of independent operating) independently separates is to a kind of configuration of FSOG oil carrier 50.Only for illustrative purposes, exploiting field A has been shown, B and D have corresponding platform 20A, 20B and 20D, and oil and natural gas pipeline A, B and D are extended by these platforms.
In the configuration of Fig. 1, the raising device 90 of the one group of top-tensioned that illustrates (raising device 90 is connected on the one or more product pipelines) is stretched over the common position (not shown, as to become easy but those skilled in the art generally will appreciate that the top that makes raising device 90 like this with interface (or butt joint) between the crossover assembly (a jumper) 70) of one group of container (or jar) or floating drum by sea bed.It will be recognized by those skilled in the art that these raising devices 90 can be single raising device, perhaps can be a plurality of raising devices that link together.Can adopt the bottom tension of multiple grappling technology (for example suction piles (suction piles) is not shown) realization maintenance raising device 90, and the top tension force of maintenance raising device 90 utilizes the buoyancy of container or floating drum.By one group of crossover assembly or flexible flexible pipe 70 (crossover assembly or flexible hose 70 are connected on each raising device, and then each raising device is connected on each product pipeline) product is transported to a turntable (or control tower) 80 on the FSOG oil carrier 50 by the top of raising device 90 subsequently.In this transportation, every kind of product can keep being communicated with by raising device 90, the independent fluid that arrives turntables 80 by flexible hose 70 by product pipeline (for example petroleum pipeline or natural gas line A, B or D).Turntable 80 can be the turntable or the outside turntable of an inside; And, generally FSOG oil carrier 50 can be arranged and is designed to wind vane formula parts about turntable 80.And then, FSOG oil carrier 50 can be equipped with and make oil carrier easy device becomes to the response of ambient conditions (for example to lift, the response of pitching, rolling and similar motion), this comprises device and the configuration of now having known, the device and the configuration that will develop after also comprising.And then, can adopt any design for turntable 80 in general, comprise design of having known and the design that will develop later on.
Can the oil and natural gas product (for example product in independent line) that arrive FSOG oil carrier 50 be measured, and measure their quality and quantity.The point of arrival measure make can be with Product transport to a specific pipeline of different qualities in (for example in the different time intervals).For this purpose, the pipeline of some configuration can be plug-in (piggable).
After measuring and measuring, can adopt and come and go oil tank ship 60 or similar device, utilize sea bed conveying route above-mentioned with petroleum storage be transported on the bank in some cases.The oil that can admit FSOG oil carrier 50 and store mix with other oil, perhaps can be in independent oil tank with petroleum storage, and this depends on the quality and quantity (for example, according to the content of sulphur, API weight, and similar index) of oil.As an example,, show 100, three oil tanks of 6 oil tanks in FSOG oil carrier 50 and be used for storing individually oil, and three oil tanks are used for storing the oil that mixes referring to Fig. 2.
Before the storage oil tank is filled, can oil be unloaded (for example by pumping or similar fashion) to a round oil tank ship 60 (ship of kinetics location or the ship that couples together with tow (or wirerope)) by (a floating) flexible pipe that leaves the stern of FSOG oil carrier 50.Can be connected with 50 disengagements of FSOG oil carrier after round oil tank ship 60 (Fig. 1) is full of, and be transported to a refinery, perhaps be transported to one and be used for unloading the harbour of (sale) and/or be transported to another storage oil tank/oil carrier.
Because on FSOG oil carrier 50, can store oil individually from different qualities of having of different oil fields or feature, so thereby the operator not only can select preferred selling spot to obtain the highest selling price (for example selling the place of oil), and can be chosen in a plurality of places sale oil, for example, include but not limited to be sold to the treatment facility and/or the plastics-production facility place of refinery and/or multiple hydrocarbon.In addition, the feasible oil from some operator or oil field of independent storage on FSOG oil carrier 50 can store and sell individually, for example, cross as above mentioned like that, make the operator can know and produce and be stored in subsequently some quality requirements (or technical standard) that all products in the independent oil tank have satisfied the operator by certain operator.The operator of FSOG oil carrier 50 can additionally have some selections: (1) buys the oil from other operators when oil enters FSOG oil carrier 50, and sell these oil in preferred selling spot subsequently, (2) collect the charges for storing oil and oil being transported to the selling spot that is determined by other operators, perhaps (3) become easily other contractual arrangement, and these contractual arrangements have been utilized the advantage that oil can be kept apart and oil is transported to special sale locations.
Natural gas transportation itself there are interests to FSOG oil carrier 50.As aforementioned, Xiang Guan natural gas may be considered to uneconomic in some cases.For example, in some system, may require the very high pressure could be through long distance Product transport to a seabed trunklines, for example, the pressure of natural gas must be higher than the pressure in seabed trunklines.Because gas product can be transported short distance arrives on the FSOG oil carrier 50, so may require lower pressure.In addition, collect the to improve value of natural gas from the natural gas in several sources.
After measuring and measure on FSOG oil carrier 50, can make natural gas enter the gas utilization process, for example such process includes but not limited to: 1) compressed natural gas and be sold to an existing main line by an outlet line; 2) compressed natural gas and be sold on the bank by an outlet line; 3) utilize natural gas as the fuel gas on the FSOG oil carrier 50, be used to generate electricity and/or produce the steam that is used for marine system and is used to heat the petroleum storage jar; 4) carry out the processing of gas at FSOG oil carrier 50 to liquid, conversion of natural gas is become the hydrocarbon of liquid, the hydrocarbon of these liquid can or mix with oil or stores individually and sell as value product (diesel oil, naphtha etc.) more; And 5) produce power (for example generating), to be sold to other the operator's (for example, other platform, production vessel and similar facilities) who produces oil and natural gas.For these processes are become easily, gas utilization/treatment facility 55 can be arranged on the main deck.
Therefore, the FSOG oil carrier 50 of this process and system can be used as the joint (or many-sided processing center of arranging) of many roads, and it can interact with one or more production platform and/or oil carriers, so that transportation and/or sale become easy.As an example, only for illustrative purposes, FSOG oil carrier 50 can be positioned at the position (for example by grappling or kinetics location) an of key (or strategy), between one or more production vessel, production platform or similar facilities.As the skilled person will recognize, with existing replacement scheme, promptly lay the very long deep water pipeline be connected on the main line and compare, it is shorter relatively to make FSOG oil carrier 50 reach time of online connection (for example, admit from production vessel, production platform or similar facilities product).The production vessel, production platform or the similar facilities that are connected with FSOG oil carrier 50 can benefit, wherein, they can avoid being connected with a main line fully, and as explained above, it may be disabled that such main line (for example may just be found an oil field) in some cases.And production vessel, production platform or similar facilities can have the position that makes things convenient for of their natural gas of transportation, moreover, in some cases, reduced pressure.And then production vessel, production platform or similar facilities can be bought the electric power that they are used to produce by FSOG oil carrier 50, and having reduced has the needs of big generating equipment (in some cases) on the production vessel.Have, FSOG oil carrier 50 can reduce or eliminate the needs for compressor again, in production vessel, may need these compressors on production platform or the similar facilities, so that natural gas is transported by production vessel, production platform or similar facilities.About last two aspects and only for illustrative purposes, generally such compressor and generating equipment are described as being arranged on for example position on production platform 20D 25.The interests of these compressor/generating equipments of minimizing/elimination (for example being positioned at the equipment of position 25) are for should being tangible for a person skilled in the art.
In addition, FSOG oil carrier 50 can will separate from the product of some exploiting field, oil field, operator or production vessel, production platform or similar facilities with different ways, advantageously makes these separated products to sell and/or to conclude the business.
Although should be appreciated that and described FSOG oil carrier 50, here the process of Miao Shuing can adopt any memory structure (for example barge or similar device) prevailingly, and these structures can be used for admitting the product from production unit prevailingly.This can generally include any current technology of having known, and other is in the technology that develops in the future.The memory structure of other imagination includes the floating platform of storage area, and these platforms can swim in the scene, and their grapplings or kinetics is positioned at the position at a key (strategy).With with similar mode described above, hull can be partitioned into the cabin, and can adopt multiple ballasting technology, these are tangible to those skilled in the art.In addition, should be appreciated that the process and the structure of description can be amplified in proportion here.For example, can adopt one or more FSOG oil carriers 50 or similar facilities, obtain the benefit of potential high productive capacity.When the production in a zone increases, can arrange more FSOG oil carrier 50 at the scene.
Fig. 3 and 4 is that the exemplary vague generalization of the process of description here represents that Fig. 3 is corresponding with the processing of oil, and Fig. 4 is corresponding with the processing of natural gas.Fig. 3 can comprise by the overall collection from the oil of the one or more product pipelines of different production facilities in step 110.Moreover, can adopt multiple technologies to realize this process.In step 120, can measure quantity and the characteristic or the quality of oil.At least three kinds of replacement schemes can appear at step 130A, 130B and 130C: can buy oil 130A, can for store and transportation to the operator 130B that collects the charges, perhaps can adopt other contractual arrangement 130C that obtains the benefit of keeping apart.In step 140, can store oil by characteristic or quality.These characteristics can be such separating fully of crossing as described above, or by the mixing or the determined specific character of product of oil product.The alternate manner of " characterization is represented " oil has also been described above; And alternate manner is tangible to those skilled in the art.In step 150, can conclude the business to oil (or sale).This transaction can comprise " place transaction " or arrive the long-term contract sale of a plurality of positions except other transaction technology.
Fig. 4 can comprise the overall collection from the natural gas of one or more product pipelines in step 160.Can adopt multiple technologies to make this process become easy.In step 170, can measure quantity and the characteristic or the quality of natural gas.Subsequently can be at the step 180A that substitutes, 180B, 180C, 180D, 180E handles natural gas, comprises except other potential possible step: compression 180A is used for the 180B that generates electricity, the inner 180C that uses, gas is processed into the processing of liquid 180C, and perhaps other utilizes process 180E.It will be recognized by those skilled in the art that some step in these steps that substitute may be overlapping to a certain extent.For example, only for illustrative purposes, can compress 180A, can utilize the natural gas 180B that generates electricity subsequently, subsequently the electricity that this natural gas the produced 180C that is used in inside then.In step 190, can conclude the business to natural gas in many ways (can be regardless of with what form concluding the business in that place thereupon, natural gas for example, liquid, perhaps electric power), these modes not only comprise those of mistake described above, and comprise that those skilled in the art are tangible alternate manners.
