20080279637 | Complementary Locking System for Locking Legs to the Deck of an Offshore Drilling Platform and Methods for Installing One Such Locking System - The invention relates to a complementary locking system for locking legs to the deck of a jack-up offshore drilling platform. The inventive system comprises the following elements at each leg, namely: at least one assembly comprising plates forming two counter-racks which are intended to be engaged with a leg rack and, on one side of the plates, at least one internal element for connecting the internal edges of the plates, at least one external element for connecting the external edges of the plates and at least one intermediate member for connecting said at least one internal element to said at least one external element. The invention also relates to methods of installing said complementary locking system on the legs of a jack-up offshore drilling platform. | 11-13-2008 |
20090123235 | OUTER PIPE SLEEVE FOR A SEA FLOOR MOORING PILE - The present disclosure provides an improved system and method for increasing an anchoring force on a pile. The concepts regarding the pile can apply whether the pile is degraded and no longer able to support its intended load, or a load on the pile has increased to a level that may overstress the pile. A sleeve can be installed even in subsea conditions over the pile and can be used to provide an additional securing force to the existing pile. The sleeve may include its own padeye for coupling an anchor line or other coupling member to a structure to be secured. The sleeve may also include an assembly of rings coupled together with at least one longitudinal member. The assembly with the rings spaced a distance away from each other may help reduce an installation friction on the sleeve, as it is installed into the sea floor. | 05-14-2009 |
20090324342 | STRUCTURE FOR THE TRANSPORT, INSTALLATION AND DISMANTLING OF AN OIL RIG DECK AND METHOD FOR USING ONE SUCH STRUCTURE - The invention relates to a structure for the transport, installation and dismantling of an oil rig deck, of the type comprising a floating hull provided with legs which can move vertically in relation to the buoyant hull and a shuttle associated with each of said legs and intended to be applied against the lower face of the deck, whereby said shuttle can be moved by the corresponding leg between a low position on the buoyant hull and a high rig deck lifting position. | 12-31-2009 |
20100021241 | SUCTION PILE SUITABLE FOR SHALLOW DEPTHS - A suction pile comprising a cylindrical wall and a piston that is movable inside the cylindrical wall. The cylindrical wall has one suction end suitable for sinking into an ocean floor. The piston delimits two chambers, one being able to be filled with water. The suction pile includes a pump for extracting the water from the one chamber and for causing the sinking of the suction end. The pump comprises a device for stopping the piston while the cylindrical wall has one water intake end to allow water to enter into the other chamber. The piston is alternatively stopped and driven in movement as the suction end sinks. | 01-28-2010 |
20100111614 | UNDERWATER BUOY WITH MODULAR MEMBERS - An underwater buoy for hanging a duct between a sea bed and the surface, the buoy including a frame and a plurality of modular members mounted in the frame, the modular members extending between their two opposite modular-member ends, the frame including a longitudinal body for receiving the extended tubular duct, and retainers mounted on the body for maintaining the modular members substantially parallel to the body. The retainers include two retaining structures spaced from each other along the body. The retaining structures are maintained in a fixed position relative to each other in order to hold at least one modular member. | 05-06-2010 |
20100147398 | DEVICE FOR TRANSFERRING A FLUID TO A SHIP, SHIP, TRANSFER SYSTEM AND ASSOCIATED METHOD - The present disclosure comprises a platform and a manifold, the latter being intended to be connected to a fluid tank. The manifold comprises a length of rigid tube defining a pipe of approximately horizontal axis and a length of connecting tube for connection to a transfer line connected to the length of rigid tube. The length of connecting tube is permanently attached to the length of rigid tube and is hinged to the length of rigid tube to allow movement relative to the length of rigid tube between: —a retracted rest position in which the length of connecting tube extends entirely inside the inner edge; and —a first or filling position, in which the free end of the length of connecting tube projects out from the outer edge of the support platform. | 06-17-2010 |
