20100092246 | Semi-Submersible Offshore Structure - A semi-submersible offshore structure for offshore operations. In an embodiment, the structure comprises a buoyant hull. The hull comprises a first elongate horizontal pontoon having a longitudinal axis, a first end, and a second end. The pontoon includes a first node disposed at the first end of the pontoon, a second node disposed at the second end of the pontoon, and an intermediate section extending axially from the first node to the second node. Moreover, the first node has a width W | 04-15-2010 |
20100143044 | Method and System for Building Modular Structures from Which Oil and Gas Wells are Drilled - A method and system for building modular platform structures from which oil and gas wells are drilled and maintained is disclosed, wherein a plurality of easily transportable, multifunctional platform modules are interconnected on-site to form a unitary platform structure. The interconnected platform modules are elevated above a ground surface on one or more legs coupled to at least one of the platform modules. The elevated, interconnected platform modules support both drilling and production operations in land-based, arctic, inaccessible, near-offshore and environmentally sensitive locations. | 06-10-2010 |
20100150661 | OPEN FACE DERRICK - An offshore oil derrick having a derrick tower, a derrick substructure, and a drilling floor. The derrick substructure is cantileverly supported by a hull, the derrick tower is supported by the derrick substructure, and the drilling floor is located on top of the derrick substructure below the derrick tower. The drilling floor comprises a v-door on the fore end; a well center approximately 40-50% of the floor length from the aft end; a plurality of setback areas; drawworks on the starboard side; a dynamic brake on the aft end of the drawworks; and a driller's station. The derrick may further include a spare line spool connected to the derrick substructure on the forward end of the derrick. | 06-17-2010 |
20100260555 | CANTILEVER SKIDDING SYSTEM ON A DRILLING RIG - The present invention provides an improved cantilever ( | 10-14-2010 |
20120224925 | CANTILEVER SYSTEM AND METHOD OF USE - A cantilever system for a rig comprising a hull, a beam coupled to the hull, an extension member coupled to the beam, and a hold-down member spaced from a support member and coupled to the extension member. A first end of the beam is extendable over an edge of the hull while a second end of the beam is positioned on the hull. The extension member increases the longitudinal length of the beam. The support member is disposed adjacent the edge of the hull. The hold-down member is configured to apply a force to the extension member in a direction toward the hull when the first end of the beam is extended over the edge of the hull. A method of increasing the capacity of the cantilever system comprises increasing the spacing between the support member and the hold-down member. | 09-06-2012 |
20140270974 | MULTI-DIRECTION DIRECT CANTILEVER SKIDDING SYSTEM - The present subject matter provides a multi-direction direct cantilever skidding system suitable for an offshore drilling system, where the multi-direction direct cantilever skidding system comprises movable guides accommodating a cantilever of a Jackup drilling unit or other mobile platform and enabling transverse skidding rails to provide direct support for the cantilever so the cantilever may be moved longitudinally and transversely. | 09-18-2014 |
20140270975 | THREE RAIL MULTI-DIRECTIONAL DIRECT CANTILEVER SKIDDING SYSTEM - The present subject matter provides a three-rail multi-direction direct cantilever skidding system suitable for an offshore drilling system, where the three-rail multi-direction direct cantilever skidding system comprises movable guides accommodating the cantilever of a Jackup drilling unit and enabling transverse skidding rails to provide direct support for the cantilever so the cantilever may be moved in both longitudinal and transverse directions. | 09-18-2014 |
