Abstract
The invention discloses a maneuvering bottom resting offshore platform which comprises a platform body provided with multiple watertight compartments and ballast tanks. Air bag compartments communicated with the outer side of the bottom of the platform body are arranged in the platform body. Air bags capable of extending to the bottom of the platform body are arranged in the air bag compartments. Multiple locating devices are arranged on the periphery of the platform body respectively. Each locating device comprises a locating pile penetrating a locating pile hole and an adjusting device used for adjusting the length of the portion, extending downwards to the outer side of the bottom of the platform body, of the locating pile. In the bottom resting process, the locating piles are placed in the locating pile holes, so that the bottoms of the locating piles make contact with the surface of a foundation, and the platform body is temporarily fixed to the foundation. Water is injected into the ballast tanks, the lengths of the portions, extending out of the bottom of the platform body, of all the locating piles are controlled, the falling position and the levelness of the platform body are adjusted, the air bags are placed down from the air bag compartments and inflated, and therefore gaps between the platform body and the surface of the foundation are filled. The maneuvering bottom resting offshore platform is flexible, capable of being evacuated at any time and well-adapted.
Description
Technical field
The present invention relates to a kind of offshore platform technology, especially relate to and can sit the offshore platform at the end and mounting method by motor driven.
Background technology
Along with constantly carrying out ocean exploitation, operation on the sea is more and more frequent, and sea also occurs that increasing ocean platform is for operation on the sea.Marine environment is the important component part that the mankind depend on for existence and development.The sustainable development of protecting the marine environment is of great practical significance.
The basis of current gravity fixing, bottom-sitting type ocean platform is built on closely knit sand more, avoids building on loosen loose sand or thicker soft foundation, and basis is smooth.For rough landform, general needs washes away, and the methods such as throwing rubble first process landform.Can produce seabed resources environment in this process and destroy, certain pollution is produced to seabed.When platform is withdrawn, be difficult to that the rubble of shop fixtures etc. is sat the spin off at the end and take away in the lump, generally also can cause the pollution of marine environment, be unfavorable for the sustainable development of marine environment.
Jack-up unit, pile foundation type platform are applicable to different landform, different geological conditionss, but need to put down spud leg and insert seabed certain depth.When platform is withdrawn, pull up spud leg, can towage extremely new place.Because spud leg need insert very dark seabed, platform is discarded or when withdrawing, consider economic cause, generally all directly can slice off spud leg, spud leg is stayed on ocean, and this is also unfavorable for the sustainable development of marine environment.
Summary of the invention

Technical solution of the present invention is: a kind of motor driven sits the offshore platform at the end, comprise the main platform body being provided with some watertight compartments and ballast tank, be provided with in described main platform body with described main platform body bottom the air bag cabin that is interlinked to the outside, the air bag that may extend to bottom described main platform body is provided with in air bag cabin, be respectively equipped with several positioners along described main platform body periphery, each positioner comprises and is located in guide pile in the stake holes of location and adjustment guide pile extends downward the adjusting device of outer length bottom described main platform body.
The watertight compartment arranged in main platform body can ensure that platform has enough buoyancy, facilitate and motor-drivenly tow to installation site, can water filling in ballast tank, platform is made to have good stability, complete and sit the end, air bag in air bag cabin can be placed on the bottom of main platform body, bottom main platform body and the space of foundation surface is filled after inflation, conveniently with difform earth surface, play main carrying effect, the gravity of platform is allowed to be uniformly transferred on ground, guide pile can extend length bottom main platform body by adjusting device regulable control, play effect that is temporary fixed and parametric controller main body levelness, when main platform body withdrawn by needs, from ballast tank draining, after making main platform body have enough buoyancy, pack up air bag and guide pile, main platform body just can move to new position, substantially disturbance can not be caused to marine environment, operation also facilitates.
Described air bag cabin and described main platform body top are interlinked to the outside.Conveniently put down and pack up air bag.
Described guide pile comprise hollow column, below column spaced sleeper layer and be set in the sleeve of sleeper surrounding, its central post bottom is connected with sleeper layer, sleeper layer and sleeve connection.Gravel can be filled in column, and be fallen into by the gap of sleeper layer on the foundation surface in sleeve, fill and lead up foundation surface, increase the contact area of guide pile and foundation surface, meet load bearing requirements.
Another kind of technical solution of the present invention is: a kind of motor driven sits method at the bottom of the seat of the offshore platform at the end, it comprises the following steps: 1., by main platform body tow to construction predeterminated position, guide pile is put down in the stake holes of location, to make bottom guide pile primary surface contiguously, main platform body is temporarily fixed on ground; 2., to water filling in ballast tank, make main platform body be moved downward to certain altitude, control each guide pile and extend length bottom main platform body, the position that adjustment main platform body falls and levelness; 3., air bag is lowered into the foundation surface bottom main platform body in air bag cabin; 4., in air bag inflate, the gap between main platform body and foundation surface filled by air bag, completed the installation that motor driven sits the offshore platform at the end.
Step 1. in, comprise and put down guide pile, the sleeve of guide pile column bottom is inserted in ground, and in sleeve, is filled the step of gravel by column inner chamber and sleeper lamellar spacing.
Advantage of the present invention is: platform has stronger mobility, possesses effect at the bottom of good seat simultaneously, less demanding to ground, and can withdraw at any time, and environmental suitability is strong.
