Description
One, technical field
The utility model relates to the used marine macrotype platform of a kind of offshore oil field development the hydraulic lifting docking facilities is installed.
Two, background technology
Offshore platform is installed the floating installation method that adopts at present, jacket will be designed to the big opening jacket that allows barge to sail into according to the width that barge is installed, platform upper module and prefabricated by land the assembling of production equipment that all need, by slide rail the platform upper module is moved on the barge, be dragged to prefabricated jacket place by barge, the installation site of centering platform upper module and jacket, the quick ballast of barge, sink, spud leg in implementation platform upper module and the jacket docks installation, butt joint finishes, barge continues ballast to be separated with the platform upper module, sail out of jacket, again that upper module and spud leg frame is integrally welded, finish the sea of console module and install.Though it is simple that existing floating method is installed construction, to compare with traditional crane barge lifting and to have saved the offshore construction time, console module and docking of spud leg are ballast sinking and the tidal ranges by barge, butt joint speed is slower.Therefore, existing floating method is installed and must be finished under the good condition of weather conditions, is subjected to the restriction of weather bigger.The installation site of centering platform upper module and spud leg is the adjusting by mooring system, such difficulty of construction is very large, and the moment that the platform upper module docks with spud leg can bump inevitably, this collision is quite big to the active force of spud leg, therefore, the risk between the platform installation period is also bigger.
Three, summary of the invention
The purpose of this utility model provides a kind of marine macrotype platform the hydraulic lifting docking facilities is installed, solve floating method offshore platform is installed, butt joint spud leg difficulty and the moment collision of platform leg butt joint spud leg (marine pile) influence the problem in offshore platform installation quality and application life.
The technical solution of the utility model realizes in the following manner:
The utility model is made up of spud leg, landing nipple and following spud leg on hydraulic motor, platform, supporting member, barge, locking cap, Convenient table, hydraulic cylinder butt joint geocoded activity leg, the platform, it is characterized in that the lower platform leg is cylindrical, on platform, vertically be provided with in the spud leg form by locking cap, Convenient table, butt joint geocoded activity leg and be that fulcrum pursues the cylindrical hydraulic component that preface connects with the platform.Wherein hydraulic cylinder and Convenient table are made as one, and butt joint movable leg and hydraulic piston are inlayed one, and hydraulic piston is located at the top of butt joint movable leg and is enclosed within the hydraulic cylinder, and the upper end of hydraulic cylinder is provided with hydraulic joint; Top at the following spud leg of platform is provided with cylindrical landing nipple, is provided with concave conical surface in the landing nipple, and the convex conical surface that is provided with butt joint geocoded activity leg bottom matches, and the outlet of the hydraulic motor on hydraulic joint and the operation ship is connected.
Compared with the prior art the utility model has the following advantages:
1, offshore platform of the present utility model is installed hydraulic lift, and is simple in structure, easy to use, by long tide and the stake of ebb docking platform, only do not finish by hydraulic system, and butt joint speed is fast, safety.
2, take barge time weak point, save the platform installation cost.
When plunging into the commercial sea the stake butt joint 3,, not influenced by wave, butt joint steadily can not cause the platform distortion, guarantees the platform installation quality.

Offshore platform has 6 or 8 legs.Last spud leg and following spud leg are arranged, and last spud leg and platform are made as one, and following spud leg is gone into the seabed with the jacket stake, and the sea level is exposed on its top, and it promptly is to be one with last spud leg and following spud leg butt welding that the ocean platform installation is docked.Head on platform with barge by supporting member during butt joint, add the method butt joint of unloading with barge, this figure has only illustrated the schematic diagram of hydraulic pressure butt joint of single stake, and the operation ship that hydraulic motor is housed is not drawn on the schematic diagram.
Five, the specific embodiment
For further disclosing the technical solution of the utility model, elaborate by embodiment below in conjunction with Figure of description:
The utility model is made up of spud leg 8, landing nipple 9 and following spud leg 11 on hydraulic motor, platform 1, supporting member 2, barge 3, locking cap 4, Convenient table 5, hydraulic cylinder 6, butt joint geocoded activity leg 7, the platform, last lower platform leg is cylindrical, on platform, vertically be provided with in the spud leg form by locking cap, Convenient table, butt joint geocoded activity leg and be that fulcrum pursues the cylindrical hydraulic component that preface connects with the platform, wherein hydraulic cylinder and Convenient table are made as one, and butt joint movable leg and hydraulic piston are inlayed one; Hydraulic piston be located at the butt joint movable leg above, and be enclosed within the hydraulic cylinder; The upper end of hydraulic cylinder is provided with hydraulic joint, and the outlet of the hydraulic motor on hydraulic joint and the operation ship is connected.Top at the following spud leg of platform is provided with cylindrical landing nipple, and the following spud leg welding with platform is provided with concave conical surface in the landing nipple, and the convex awl that is provided with butt joint geocoded activity leg bottom matches.
Barge carries platform and sails jacket inside into, behind the anchoring location, the piston of the cylinder device on the platform in the spud leg moves downward, promoting butt joint geocoded activity leg descends, dock with the sea spud leg that fixes of having driven piles, behind the butt joint location, the barge ballast sinks, on progressively that the platform weight load transfer is the extremely marine spud leg, at last, barge separates with platform and sails out of jacket, and then, hydraulic piston (or hydraulic jack) slowly descends, spud leg docks fully with spud leg on platform, the welding of spud leg on the platform and spud leg is fixing, dismantle bolt on the locking cap proposes spud leg inside from platform top hydraulic lifting member, finish the sea of macrotype platform and install.Cleaning and repairing hydraulic component is other platform to be installed get ready.
