Description

Double curved surface shape floating production oil storage platform

Technical field

The present invention relates to a kind of double curved surface shape floating production oil storage platform, belong to field of ocean engineering.

Background technology

FPSO(Floating Production Storage and Offloading System, floating production storage unit) be the offshore floating type oil gas treating device that oil-collecting gas disposal, oil storage and emptying, heat supply, generating, control and vital function are integrated, mainly formed by three parts such as oil gas disposal system (upper module), oil storage and unloading system (container-like buoyancy aid) and mooring systems.

The performance of FPSO is mainly by the good and bad of its safety and operability and the situation that meets of functional requirement is examined or check.Consider from safety and operability, FPSO should have good stability and hydrodynamic performance; Consider from functional requirement, FPSO should have larger oil reserve, load-carrying capacity and floor space.The buoyancy aid profile of FPSO determines its safety, motion characteristics, buoyancy aid intensity, oil storage efficiency and laid down cost and running cost, and the exercise performance of FPSO directly affects normal work, the production quality of crude oil and personnel's the traveling comfort of top equipment and instrument.

The old oil tanker transformation of traditional FPSO general using forms, or follows the design concept design of standard boats and ships, the buoyancy aid of newly-built barge shape.It is following not enough that elongated and asymmetric ship type buoyancy aid makes permanent mooring exist in the FPSO in a certain marine site.

One, ship type floating motion poor-performing.Relatively large because of the waterplane area of ship type buoyancy aid, natural heaving period generally, in wave energy concentrated area, causes heave amplitude larger; Length and width yardstick differs greatly, and causes buoyancy aid very responsive to the action direction of environmental forces, and especially rolling is serious, affect equipment and instrument normal work, produce quality, emptying, helicopter landing, delivery ship alongside and personnel's the traveling comfort of crude oil.

Its two, productive costs and operation cost are high.In order to improve exercise performance, reduce design load, ship type FPSO mono-general configuration, with the single buoy mooring system of capstan head and fluid coupling, makes FPSO have 360 ° of comprehensive vane effects that rotate freely, the destructive force of bringing to evade wind, wave, stream.But capstan head and fluid coupling are expensive, and the production cycle is long, designer and maker are little, and need often maintenance, have the potential idling period causing because of reasons such as seal leakage, and field produces cost is increased greatly.

Its three, buoyancy aid shape affects its intensity.Longitudinal hogging of slender ship type buoyancy aid and in the flexural load that hangs down very large, buoyancy aid is easily cracked expand and suffers endurance failure.For the FPSO that uses obsolete vessel repacking, the boats and ships that especially build up after 1985, because used high-tensile steel, problem of fatigue damage is particularly serious more.In order to meet requirement of strength, generally need to carry out local structure reinforcement, further increase the cost of FPSO.

Its four, oil storage efficiency is undesirable.The block coefficient of ship type buoyancy aid is generally 0.75~0.93, so the oil storage efficiency of ship type FPSO (being the oil reserve of unit plan area) is also not ideal enough.

Its five, floor plan is unreasonable.It is generally that life building is arranged in to bow or stern that the upper module of ship type FPSO is arranged, causes life building always between dangerous oil gas, has great potential safety hazard; Slender type buoyancy aid and deck increase and between technical module, connect the length of piping and arrange difficulty, and its general layout follows the arrangement of oil tanker, cause technological process piping complexity; The deck level that length and width dimension scale is fixed is also not easy to carry out the optimal design of general layout.

Therefore, along with the minimizing, people that can transform oil tanker quantity are to the re-recognizing and demand to marginal oil field of FPSO, in the urgent need to improving the design of FPSO.

The FPSO of a new generation has adopted the buoyancy aid form that more can meet FPSO functional requirement, and wherein, representational is the cylindrical shape FPSO series of SEVAN MARINE company of Norway research and development.Its unique cylindrical shape buoyancy aid profile has been eliminated head and has been shaken excitation, make buoyancy aid all directions there is similar exercise performance, but still there are some shortcomings in cylindrical shape FPSO, as larger in buoyancy aid waterplane, displacement is less with respect to upper module weight, and heaving amplitude is larger, easy excitated vortex-induced vibration, and floor space, compared with little and compact, is unfavorable for dangerous area and separating of non-hazardous area etc.

In sum, in order to give full play to the potentiality in FPSO development of the field at sea, be necessary to research and develop the FPSO buoyancy aid form of novel concept.
