Description
Technical field
The present invention relates to hinged truss formula binary crane ship, belong to ship domain.
Background technology
The jacket platform being on active service with early stage and subsea production system enter date of retirement, these retired catheterostats
Platform and subsea production system need to be removed.The superstructure of jacket platform is generally higher, and weight is larger, and dismounting is compared
Difficult.In addition large-scale boat structure gradually adopts modularity to build, and finally carries out general assembly in harbour or sea to module.These
Module weight generally reaches a few kiloton, and shape difference is larger.Carry out removing in these structures, need one kind in installation exercise
Being capable of operation is steady, elevating capacity is strong, job area is wide operating platform.Existing crane ship mostly is single hull structure, also adopts
Form combinative structure with monomer with side buoyancy tank.In order to increase lifting radius, arm can be arranged in stem end or stern by crane ship
End, this crane ship, when lifting by crane large and heavy objects, can cause larger trim or heeling moment.In order that hull balance it is necessary to
Ballast water distribution in adjustment hull.During lifting, arm and hull junction can produce larger stress concentration, therefore hang
Arm lower end and hull junction need to carry out structural strengthening.
The sea-keeping that catamaran has generally had, binary is arranged in sea-keeping and requires to obtain on higher ship extensively should
With, such as binary passenger boat, binary surveying vessel etc..Existing crane ship also has using binary arrangement or is similar to binary arrangement.
Find, the binary disclosed in the patent document of Publication No. CN 102642601B may move Full Rotary through retrieval
Crane ship, using couple structure, connects two hulls using the fixed deck positioned at hull end, each installation one on the hull of left and right
The Full Rotary turned crane of platform, turned crane utilizes the mechanism of Hydraulic Creeping formula loop wheel machine running track can move along along the deck of left and right
Dynamic.This scheme adopts two cranes, is only provided that two Heave Heres, should not lift by crane heavy die block；In addition rise inside two ships
During lift heavy thing, larger moment of flexure can be produced above deck, unfavorable to the intensity on deck.The patent of Publication No. CN102530189A
The catamaran for ocean engineering disclosed in file using two hulls parallel and that there is adjustable distance as main body, two hulls
Deck rear portion arrange slideway, two parallel casings above hull across two hulls, can be along track slide anteroposterior.This scheme two tanks
On horizontal positioned pedestal, when two ship spacing are larger, form large span simply supported beam, if during lifting superduty module, casing needs higher
Intensity, cause that body structure materials are more, structure is overweight；In addition, when hull occurs larger rolling, can cause below casing
Support one side stress is excessive, easily causes structural deterioration.
