Abstract
The utility model discloses a whole installing the system that dismantles of marine fixed platform jacket, its characterized in that: including barge hull, anchor winch, slide, piston shoes, ballast tank and life building module, life building module, anchor winch, slide setting are in barge hull upper portion, life building module is located the barge hull is anterior, slide and anchor winch symmetry set up barge hull upper portion, the slide is provided with piston shoes. The utility model discloses can realize to the large -scale jacket of deep water whole demolish, installation jobs, simple structure, work progress do not need large -scale crane ship, economical and practical, can be extensively at sea the fixed platform jacket demolish the installation field and use.
Description
Technical field
The utility model relates to one and removes and installs system, particularly a kind of fixed offshore platform jacket integral demounting installation system.
Background technology
CHINESE OFFSHORE has built up nearly 200 of jacket platform, and wherein nearly half is last century eight, the nineties construction, and the design life of these jacket platforms mostly is 20 ~ 25 years.According to design life, a lot of platform has reached or close to the retired time limit.Traditional marine hoisting device is adopted to remove these platform jackets costly.Meanwhile, because exploitation of offshore oil and gas is just towards maximization, compartmentalization future development, need larger jacket, this just has higher requirement to the demolition technique of marine ultra-large type jacket and operational capability.
The equipment being conventionally used to marine jacket lifting mainly contains crane ship and Semi-submersible type hoisting platform two class, and wherein crane ship load-carrying ability is at below 7500t, is difficult to carry out the overall pulling down of large jacket; Semi-submersible type hoisting platform load-carrying ability can reach 14000t, but rates is expensive.The utility model provides a kind of fixed offshore platform jacket and removes and installs system, and this system can realize overall pulling down, installation exercise to large jacket, and work progress does not need crane ship, economical and practical.
Summary of the invention
The purpose of this utility model is exactly the deficiency existed for prior art, provide a kind of fixed offshore platform jacket and remove and install system, this system can realize overall pulling down, installation exercise to large jacket, and work progress does not need crane ship, economical and practical.
Its technical scheme is: a kind of fixed offshore platform jacket removes and installs system, it is characterized in that: comprise barge hull, anchor winch, slideway, piston shoes, ballast tank and life building module; Described life building module, anchor winch, installation of slide track are on described barge hull top; Described life building module is positioned at described barge fore-body, and described slideway and anchor winch are symmetricly set on described barge hull top, and described installation of slide track has described piston shoes; Described slideway is symmetricly set on barge deck, described slideway is provided with slidably piston shoes, and described piston shoes have forced locking device.Described ballast tank is positioned at barge hull, arranges the pressure loading system matched with it, realizes hull handstand and also can realize floating by Quick drainage in ocean; Described barge hull bottom is provided with full circle swinging screw propeller.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model external overall structural representation.
Accompanying drawing 2 is the utility model internal ballast tanks structural representations.
Accompanying drawing 3 is the utility model A/C frame schematic diagrams.
Accompanying drawing 4 is the utility model hull floating schematic diagrams.
In accompanying drawing: barge hull 1, slideway 2, piston shoes 3, anchor winch 4, life building module 5, ballast tank 6, jacket 7.
Detailed description of the invention
1-4 by reference to the accompanying drawings, the utility model will be further described:
As shown in Figure 1, the utility model provides a kind of fixed offshore platform jacket integral demounting installation system, and it comprises barge hull 1, slideway 2, piston shoes 3, anchor winch 4, life building module 5, ballast tank 6.Life building module 5 is arranged on stem position, barge hull 1 top, and inside is provided with control cabin, and rotatably, in hull handstand process, floor is parallel to the water surface all the time for life building control cabin and residential development.Slideway 6 and anchor winch 4 are arranged on barge hull 1 top, and be arranged symmetrically, every bar slideway arranges the piston shoes 3 of some as the case may be.Piston shoes 3 have two kinds of catch gears, a kind ofly the piston shoes be free to slide can be fixed on slideway assigned address, it is fixing that another kind of automatic locking mechanism realizes jacket 7 spud leg by under-water robot.Anchor winch 4 is arranged on hull top, and ballast tank 6 is arranged in hull.
Described ballast tank 6 is provided with quick pressure loading system, realizes hull 1 and stands upside down, and by being arranged on the piston shoes 3 A/C frame on slideway 2, realizes large jacket 7 overall pulling down; Hull 1 bottom is provided with full circle swinging screw propeller, for advancing hull 1 and locating, can realize the dismounting of jacket 7, installation exercise.
In sum, the utility model when carrying out the operation of large jacket overall pulling down, first by hull 1 near targeted conductor frame 7, ballast tank 6 ballast water realizes hull 1 handstand state, be positioned targeted conductor rack position, piston shoes 3 automatic locking mechanism A/C frame 7 spud leg (as shown in Figure 3), ballast tank 6 draining, ship stern floats, stem is positioned at more than the water surface (as shown in Figure 4) all the time, hull 1 emerges completely to operational configuration, completes dismounting, sails out of target marine site.Installation process in contrast, but barge do not need stand upside down.
The beneficial effects of the utility model are: realize Large marine jacket overall pulling down, installation exercise, operating efficiency is high, significantly reduce Potential Working Time For Operation At Sea, reduce operating risk, other Large marine construction ships are not needed to assist, economical and efficient, can extensively at sea apply in fixed platform assembly and disassembly field.
