Description
Technical field
The present invention relates to pipe laying crane ship, particularly relate to a kind of with moon pool, the ship type of the semisubmersible pipe laying crane ship that is suitable for deepwater work.Belong to ocean engineering field.
Background technology
Offshore oil and gas field is developed, and be unable to do without the handling installation of Large marine equipment and the laying of seabed delivery duct.Pipe laying crane ship as important equipment indispensable in the development process of marine oil gas field, it not only the lifting of the large part such as applicable offshore oil platform upper module and the auxiliary time water of dismounting, jacket and in place, also can be used for installing under water and the operation such as laying, maintenance of sea-bottom oil-gas pipeline.
Along with China's offshore oil and gas field exploitation moves towards deep water from shallow water, large-sized deep water pipe laying crane ship becomes the emphasis of research day by day.
At present, the ship type that deep water pipe laying crane ship adopts has: conventional monomeric ship and semisubmersible two kinds of ship types, pipe laying mode is mainly divided into: S type pipe laying and J type pipe laying two kinds of modes.Because semisubmersible ship type is in rough water quality and accessible load-carrying ability etc., comparatively conventional monomeric gear has obvious advantage, simultaneously, J type pipe laying mode is compared with S type pipe laying mode, with the obvious advantage in dynamic positioning demand and pipeline unrelieved stress etc., therefore, the lifting laying work in the severe marine site of deepwater environment, more and more trends towards adopting semisubmersible J type pipelaying vessel ship type.
Existing deep water semi-submersible J type pipe laying crane ship, is generally furnished with two main hoisting cranes of large-tonnage on the quarter, and the position be arranged on pipe laying crane ship by the pylon of J type pipe laying system is different, has following three kinds of arrangements:
1) pylon is arranged between the main loop wheel machine of pipe laying crane ship stern, send guard system to arrange along pipe laying crane ship captain direction;
The pylon of this kind of mode is arranged in main loop wheel machine operating range, and self loop wheel machine can be utilized to carry out lifting, the dismounting of pylon.But because pylon is between two main loop wheel machines, the yardstick of J type tower is limited to the spacing of hoisting crane, and meanwhile, pylon again limit the degreeof turn of hoisting crane, and both interfere each other.Therefore, when carrying out hoisting operation, pylon need be removed.This just causes the conversion cannot carrying out operation function between pylon and hoisting crane in shorter time gap.In addition, because the pylons of nearly 4000 tons heavy are located between two main loop wheel machines, make the weight of pipe laying crane ship stern more concentrated, be unfavorable for floading condition balance and Structural Strength Design;
2) pylon is arranged in the topside of pipe laying crane ship, and upper guard system is longitudinally arranged, pipeline is along pipe laying crane ship cross direction horizontal feed;
The deck working area degree of utilization of this kind of mode is higher, and J type laying work line does not affect original layout of deck plane, generally, compares the transformation of the ship type be suitable for existing pipe laying crane ship.Its major defect is: because J type laying work line is located at the hull side of pipe laying crane ship, and this just forms very large heeling moment to pipe laying crane ship, therefore, needs to balance by horizontal ballast, thus, unfavorable to pipe laying lifting hull stability; And because rotor inertia is left-right asymmetry, pipe laying crane ship is cross motion poor-performing in wave.In addition, because pipe laying masterpiece is used in the topside of pipe laying crane ship, add extra turn first moment, make when laying work, dynamic positioning and the thrust of moving spent by ship of pipe laying crane ship will increase greatly.And, when from boat navigation, steady course is handled and brings certain difficulty;
3) pylon is arranged in the middle part of stem, and laying work line is longitudinally arranged;
In this kind of mode, the weight being positioned at pipe laying crane ship stem pylon can partial balancing stern hoisting crane weight, is conducive to floading condition balance.But, because pylon is not located in the operating radius of the main hoisting crane of ship stern, therefore, this kind of pipe laying crane ship cannot rely on equipment of itself to carry out dismounting to pylon, and under the operating mode of navigating by water and meet storm, the safety of its towering pylon to stability and structure itself is unfavorable; Meanwhile, the navigation of band pylon, also can produce certain impact to the navigation visual field, thus, need to arrange extra tower cupola; Meanwhile, for the installation of the annexes such as subsea pipeline-end (PLET), certain difficulty is brought; In addition, because operating line is positioned at the ship midship of pipe laying crane ship, therefore, be positioned at the life building of stem, will be separated into two parts in left and right, the contact of the personnel of giving and escape are brought adverse influence by this.
