A ship body comprises an upper platform, a plurality of upright columns and two lower floaters, wherein the upright columns are fixed at the two sides under the upper platform and are arrayed in parallel; the lower floaters are fixed at two sides, are arrayed in parallel and are connected to the upright columns; and a crane is fixed on the tail part of the upper platform. The ship form is characterized in that a centrum structure expanding outwards from bottom to top is formed by the joints of the upper parts of the upright columns on the stem and the upper platform; the outer sides of the lower edges of the upright columns are matched with the deck molded lines of the lower floaters; the upper sides of the upper edges of the upright columns are aligned with the side boundaries of the upper platform; the joints between the bottoms of the upright columns and the lower floaters are in bulbous bow arch-shaped natural transition; and after being connected in such a manner, the ship form of the stem is of a streamline structure. The ship form for the semi-submersible type hoisting pipe-laying ship can be used for maximally reducing the water resistance and improving the routing speed of the pipe-laying ship under the condition of ensuring the structural strength and buoyancy of the ship body.
Description
Technical field
The present invention relates to pipelaying vessel, relate in particular to a kind of ship type of semisubmersible lifting pipelaying vessel.Belong to marine oil engineering field.
Background technology
At sea in the petroleum development engineering, usually,, oil gas is carried by submerged pipeline laying submerged pipeline between the oil production platform or between oil production platform and the land.Undersea pipe-laying is an important component part of deep-sea oil gas field development ﹠ construction, and aspects such as exploitation, production and the product of offshore oil and gas field be defeated are outward played crucial effect.
The laying of submerged pipeline is normally carried out on the piping work ship, on the ship type of hull, roughly can be divided into: barge formula, common ship pattern and semisubmersible.
Barge type pipelaying vessel is with respect to other type pipelaying vessel, and its stability is less relatively, and it is more steady generally to be used for environment, the marine site that the depth of water is more shallow relatively.Barge formula pipelaying vessel displacement is bigger, and draft is less relatively, and therefore, the pipelaying vessel that majority is used for sea, beach and simple sea is the barge type.
Common ship type pipelaying vessel draft is darker relatively, is fit to that needs carrying is reseted fully or uses during high lifting force.
Semisubmersible lifting pipelaying vessel is a kind of ship type of large-scale marine lifting pipelaying vessel.Semisubmersible lay vessel ship type is huge, and operating line is arranged on the central authorities of ship more, and its maximum characteristics are exactly that stability is strong, can be in rugged environment relatively and marine site, deep-sea construction operation.Owing to have good wind resistance seakeeping performance, positioning performance, possess the ability of operation under deep water and severe sea condition, hoisting capacity huge (maximum 2 * 7100t), satisfy the various needs that marine oil and gas exploitation and large-scale marine engineering construct and extensively be subjected to the favor in market.
The semisubmersible lifting pipelaying vessel overwhelming majority is used on drilling platform, production of hydrocarbons platform, it and conventional boats and ships maximum be not both its outer shape, be called the ship type in the industry.The ship type that it is different from barge type and common ship type ship oceangoing ship is a buoyancy aid, but is made up of several buoyancy aids.
As Fig. 1, shown in Figure 2, the hull of representative type semisubmersible lifting pipelaying vessel comprises: upper mounting plate 1, be fixed on several columns 2 of both sides arrangement in parallel below the upper mounting plate 1 and be fixed on the both sides arrangement in parallel and with two following buoyancy aids 3 of several column 2 bonded assemblys, the afterbody of upper mounting plate 1 is fixed with hoisting crane 4; Required buoyancy when following buoyancy aid 3 provides towage and operation.Column 2 is mainly used in and connects buoyancy aid 3 and upper mounting plate 1 down, and its cross section is generally rectangle, also has certain buoyancy.During operation, the part submerged of following buoyancy aid 3 and column 2, floating line is in the column cross section.Formed the small-waterplane-area phenomenon, reduced wave relevant and stream greatly and acted on load on the platform with waterplane area, and its bigger moment of inertia of waterplane required stability when the platform operation is provided.Upper mounting plate 1 is the main place that equipment is deposited, personnel live work.On the structure and function of its hull of semisubmersible lifting pipelaying vessel, column 2 is most characteristic and is crucial structure that the quantity of column 2, shape, layout are the key factors that influences semisubmersible lifting pipelaying vessel route speed.
Because it is rectangle that rectangle or bottom are adopted in column 2 its cross sections of existing semisubmersible lifting pipelaying vessel more, top is near outwards expanding to trapezoidal with upper mounting plate 1 junction, the bow that buoyancy aid 3 and upper mounting plate 1 back are constituted under connecting is also for trapezoidal, though guaranteed reserve buoyance, but, because column 2 length own are bigger, during navigation, it is bigger to be subjected to resistance to water-flow, is difficult to guarantee the rapidity of pipelaying vessel navigation.
