摘要： Various embodiments relate to a method and a seabed supported base structure for providing a shallow water drilling terminal, where a prefabricated floating seabed substructure is towed to site, ballasted to rest on the seabed and/or piled to the seabed forming a seabed foundation. The seabed supported base structure is provided with at least one cantilevered unit with openings for drilling of wells, projecting sideways out from the exterior side of a vertical wall, terminated above sea level. A prefabricated floating drilling module provided with an outrigger with sidewise movable drilling device is towed to the site, guided into the seabed substructure through an opening in the wall structure at the periphery of the base structure, ballasted and mated onto the base structure, whereupon wells are drilled from a drilling gear. Upon completed drilling and operation of the wells, the drilling unit is removed and substituted by a production unit.

摘要： An offshore drilling vessel includes a floating hull subjected to heave motion. The hull includes a moonpool and a drilling tower near the moonpool. A drilling tubulars storage rack is provided for storage of drilling tubulars. The vessel includes a heave motion compensation support that is adapted to support a slip device whilst performing heave compensation motion relative to the heaving motion of the vessel. A racking device is provided with a heave motion synchronization system that is adapted to bring a tubular retrieved from the storage rack in heave motion into a vertical motion that is synchronous with the heave compensation motion of the string slip device. The racking device includes vertical rails and at least two separate motion arm assemblies mounted on said vertical rails. Each separate motion arm assembly includes its own vertical drive which is electrically connected to the heave motion synchronization system.

摘要： An oil storage, loading and offloading system includes a submerged oil storage tank with multiple vertically placed flexible containers. The system directly connects to the topsides of an offshore oil production platform above water to assist oil loading and offloading operations. During loading, oil is pumped in and stored inside flexible containers, which are expanded to displace equivalent amount of water out of the oil storage tank; during offloading, oil is pumped out from flexible containers and the reduced volume of each contracted container is then filled in by the equivalent amount of water from the surroundings There is no physical contact between water and oil. The submerged tank on-bottom weight has a limited variation during the loading and offloading operations. This disclosed system can be utilized for fixed offshore platforms, especially for shallow water marginal field developments, and for deepwater floating platforms such as SPAR and semi-submersible (SEMI) structures.

摘要： A vessel adapted to perform subsea wellbore related operations involving a riser string that is assembled from releasably interconnected riser sections and extends between a subsea wellbore and the vessel. The riser string vertical handling system of the vessel includes a controlled motion device that is adapted to displace the riser string lifting tool in at least one horizontal direction relative to the riser spider device at least whilst travelling between the elevated and lowered position thereof loaded by the riser string suspended from the riser string lifting tool, thereby allowing to establish an inclined travel path with selectively variable inclination of the riser string lifting tool relative to an imaginary vertical line through the riser string passage of the riser spider device, e.g. said inclined travel path having an inclination selected to correspond to an actual water current induced inclination of an upper portion of the riser string during the riser string assembly process.

摘要： An offshore drilling rig configured for lowering and/or raising a string of tubular equipment into a subsea borehole. The drilling rig includes a drill deck; a first hoisting system being adapted for raising or lowering a first load carrier along a vertical first hoisting axis, wherein the first hoisting system is supported by a first support structure extending upwardly relative to the drill deck; a second hoisting system being adapted for raising or lowering a second load carrier along a vertical second hoisting axis located apart from the first hoisting axis, wherein the second hoisting system is supported by a second support structure extending upwardly relative to the drill deck; and a joint operations well center on the drill deck. During joint operations, the first and second hoisting axes are preferably located apart from the joint operations well center.
