MARINE JACKUP PLATFORM APPARATUS

A leg support system for mobile, marine, jackup units of the type having a floating barge having telescoping legs upon which the barge can self-elevate. The jack towers are movably positioned on the vessel deck and are adapted to tilt into variable angles so that the legs can be spread wider apart when they rest on the bottom of the ocean. The bottom of the legs are fitted with a foot (can). With the cans further apart and the legs inclined to preselected variable angles, the stability against overturning is increased, and leg bending moments are reduced during all conditions; including storms, transit, drilling and "punch through." Because of this adjustable leg inclination feature, the tilted legs inboard chords can be connected to adjacent chords at the top of the legs during transit conditions, thereby reducing the leg stresses. The jack tower guidance system consists of upper and lower guide rollers which contact the specially shaped chord sections and support the legs as they are ...

Jacking system with auxiliary structure comprises a working deck structure, a plurality of support columns movably connected to the working deck structure, cantilever arranged on the working deck structure, drilling derrick located on the cantilever, one or more support main structures located on the sea bottom, and a plurality of movable supports, each of which is rigidly connected to the main deck structure. Working deck structure, a plurality of support columns, cantilever and drilling derrick form a jacking drilling assembly. Method consists in the fact that during initial assembling of the jacking system, a plurality of support columns is being lowered to the sea bottom to lift the working deck structure with required height. During assembling of the jacking system, a plurality of movable supports passes from the working deck structure to said one or more support main structures so, that said one or more support main structures support the weight of the main working deck structure while replacing one or more of said plurality of support columns. Said one or more support columns, replaceable to said one or more support main structures, are defined as support columns not supporting the weight, and the rest of a plurality of support columns, not replaceable to said one or more support main structures, are defined as support columns supporting the weight. After assembling of jacking system with auxiliary structure, the support columns not supporting the weight are being removed from water in required position, support columns supporting the weight together with said one or more support main structures via movable supports support the working deck structure. EFFECT: technical result is supporting of the jacking assembly, simple dismantling for reusing after drilling required wells. 10 cl, 9 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 ...

Method of installing and using offshore well development and production platforms

A development and production facility for an offshore oil or gas field is constructed and drilling of wells is performed using a jack-up drilling platform in an improved manner. The facility is composed of a development well platform and a production platform, each of which is composed of a modular prefabricated unitary deck assembly of substantially turn-key completeness and of a prefabricated jacket or leg assembly to which the deck assembly is matable. Crane or derrick barges are used only to position the deck assemblies on the leg or jacket assemblies after the latter assemblies have been placed erect on and secured to the sea floor by use of the jack-up platform. The development well platform is constructed first so that drilling of development wells can be performed from the jack-up platform through the former platform concurrently with the placement and completion of the production platform.

Method for executing gravity offshore structure and the structure

In constructing a gravity offshore structure at an installation site having a relatively large depth of water, a footing (2) serving as a float as well is built in a dry-dock, and a cylinder (4) which constitutes an underwater substructure is built on the footing (2) in an offshore yard located at a shallow sea area. The cylinder (4) is assembled in a telescopic manner, and an upper cylinder (4C) serves as a float. Ballast water Wb is injected into the footing (2) at the installation site of a large depth of water to submerge the footing (2), and a lower cylinder is extended while the upper cylinder (4C) acts as a float. After the footing reaches the bottom of the water, a pad material is filled in the footing (2) and the cylinder (4), and an offshore superstructure is constructed on the upper portion of the cylinder (4). Since a cylindrical-shaped underwater substructure is built in a telescopic manner on the footing serving as a float as well, a structure for a large depth of water can be built with easy stability as a float even in a region where it is not possible to ensure a calm sea area of a large depth along the coast. Buoyancy and gravity are harnessed at an installation site having a large depth of water to readily extend a body and submerge a huge structure without the use of a large-scale drive apparatus.

A cantilever system and method of use

리그용 캔틸레버 시스템은 선체, 선체에 커플링되는 빔, 빔에 커플링되는 연장 부재, 지지 부재로부터 이격되고 연장 부재에 커플링되는 억제 부재를 포함한다. 빔의 제 1 단부는 선체의 에지를 넘어 연장 가능하지만 빔의 제 2 단부는 선체 상에 위치된다. 연장 부재는 빔의 길이방향 길이를 증가시킨다. 지지 부재는 선체의 에지에 인접하여 배치된다. 억제 부재는 빔의 제 1 단부가 선체의 에지를 넘어 연장될 때 선체를 향하는 방향으로 연장 부재에 힘을 가하도록 구성된다. 캔틸레버 시스템의 용량의 증가 방법은 지지 부재와 억제 부재 사이의 간격을 증가시키는 단계를 포함한다. The rig cantilever system includes a hull, a beam coupled to the hull, an extension member coupled to the beam, and an inhibiting member spaced from the support member and coupled to the extension member. The first end of the beam is extendable beyond the edge of the hull, but the second end of the beam is located on the hull. The extension member increases the longitudinal length of the beam. The support member is disposed adjacent to the edge of the hull. The restraining member is configured to exert a force on the elongate member in a direction toward the hull as the first end of the beam extends beyond the edge of the hull. The method of increasing the capacity of the cantilever system includes increasing the distance between the support member and the restraining member.
