Abstract
Catamaran of sea engineering comprises two parallelly arranged hulls. Each of the two hulls is provided with several slide ways; decks of the two hulls is mounted with a upper floating box whose bottom is installed with a locking structure through which the upper floating box connects the two hulls. The catamaran of the utility model installs or detaches the marine petroleum platform of different breadth by adjusting distance of the two hulls, especially adapting to super large platform blocks of above 10000 tons; simultaneously, the catamaran can directly execute marine construction as towing and installation, thereby avoiding high risk lightering process and reducing work load of debugging marine equipment.
Description
Technical field
The utility model relates to ocean engineering construction boats and ships, relates in particular to the ocean engineering catamaran that a kind of installation, dismounting and aerogenerator that is used for ultra-large type marine oil and gas development platform upper chunk installed.Belong to marine oil engineering field.
Background technology
In the petroleum development engineering, need build various marine oil and gas development platforms such as oil production platform, accommodation platform, central processing platform at sea at sea.The marine oil and gas development platform mainly comprises: platform upper chunk, supporting construction (as jacket or floating structure) under water after the supporting construction installation, need to install marine oil and gas development platform upper chunk under water.Because the volume and weight of upper chunk was not very big in the past, adopted crane barge lifting operation mode to its installation or dismounting usually.
Along with the fast development of marine oil industry, marine oil and gas development platform forward is multi-functional, the integrated direction development, and flat-bed size, weight are also constantly increasing.Because the restriction of existing crane barge load-carrying ability can not have been satisfied current a lot of large ocean platform and install or removed requirements of one's work.For this reason, need it is divided into the polylith lifting for the platform that exceeds the crane barge load-carrying ability, then, carry out integral body butt joint and system debug more at sea, to cause the marine burn in period that reaches the time about half a year like this, because the expense of marine debugging is debugged far above land, so, do very uneconomical like this.
In order to overcome the problem of crane barge load-carrying ability deficiency and the marine debugging cost of great number, at present,,, also often adopt floating holder method to carry out large-scale chunk integral installation except adopting the method for piecemeal lifting for the installation of large ocean platform chunk.
As Fig. 1, Fig. 2, shown in Figure 3, the auxiliary vessel that adopts the floating holder method of single ship that marine oil and gas development platform upper chunk is installed comprises: hull 1, hull 1 are provided with two parallel slideways 2.Chunk towage and when installing is fixed on upper chunk 3 on two parallel slideways 2, in hull 1 enters jacket 4 after, carry, dock, move back several steps such as ship through toning, upper chunk 3 is installed on the jacket 4.
It is very effective to adopt the floating holder method of single ship to install or remove large ocean oil and gas development platform chunk.But for the ultra-large type marine oil and gas development platform upper chunk that surpasses 10000 tons, the floating holder method of traditional single ship can be subjected to great limitation again.At first, it will be subjected to the restriction of single hull load-carrying ability, and barge need increase when chunk weight increases, and then its molded breadth also can increase thereupon, need to increase the span of jacket and chunk like this, thereby significantly increase the structural steel amount of jacket and chunk.For this deep water platform of SPAR (deep water buoy platform), because its part in water is an enclosed construction, chunk then can't be installed with the floating holder method of single ship in the space that does not allow boats and ships enter.
The utility model content
Main purpose of the present utility model is to overcome the shortcoming that existing monomer auxiliary vessel exists, and a kind of ocean engineering catamaran is provided.It can carry out the installation of large ocean oil platform chunk or the dismounting of different in width by the distance of adjusting between two ships, is particularly useful for installation or dismounting work that weight surpasses 10000 tons ultra-large type platform chunk.Simultaneously, can directly carry out offshore constructions such as towage and installation, avoid the bigger work progress of transferring of risk, significantly reduce the work capacity of offshore set-up debugging chunk.
The purpose of this utility model is realized by following technical scheme:
A kind of ocean engineering catamaran, it is characterized in that: the hull that comprises two arrangement in parallels, respectively be provided with several slideways on two hulls, one top buoyancy tank is installed on the deck of two hulls, a latch-up structure is installed in the bottom of this top buoyancy tank, and the top buoyancy tank connects as one two hulls by latch-up structure.
Described latch-up structure comprises: two tooth bars, two tooth bars are installed in the both sides of buoyancy tank bottom, top respectively, and a side of tooth bar is installed a Horizontal lock locking structure and several vertical positioning plates, and this Horizontal lock locking structure and vertical positioning plate are fixed on the hull; One side of this tooth bar also is equipped with a gear drive, and the wheel and rack of this gear drive is meshed.
Described tooth bar is the single cog structure.
Described Horizontal lock locking structure comprises: a bracing frame, and this bracing frame is fixed on the hull, and several hydraulic jacks are installed on the bracing frame, and a locking tooth bar is installed on several hydraulic jacks, and this locking tooth bar is corresponding mutually with tooth bar; The two ends of locking tooth bar are respectively equipped with support, and this support is fixed on the hull, and support is equipped with several hydraulic jacks, and the piston rod of jack is relative with the locking tooth bar.
Described gear drive comprises: a drop-gear box, and an end of this drop-gear box is connected with an electrical motor, and the wheel and rack of the drop-gear box other end is meshed.
Described vertical positioning plate is the right angle flanged plate that steel plate is made.
The beneficial effects of the utility model: the utlity model has offshore construction time weak point, the advantage that fabrication cost is low.It can carry out the installation of large ocean oil platform chunk or the dismounting of different in width by the distance of adjusting between two ships, is particularly useful for installation or dismounting work that weight surpasses 10000 tons ultra-large type platform chunk.Simultaneously, can directly carry out offshore constructions such as towage and installation, avoid the bigger work progress of transferring of risk, significantly reduce the work capacity of offshore set-up debugging chunk.In addition, this buoyancy tank can also also can be used as life building and stay for personnel as storage space.After the top buoyancy tank is removed, also it can be used as two single ships; Also can carry out the installation of aerogenerator or the offshore constructions such as installation of dismounting and deep water platform, can use by a ship more.
