摘要： The instant disclosure relates to a system and method of constructing drilling and production platforms that are particularly useful in remote, inaccessible and/or environmentally sensitive operating environments. According to one aspect of the invention, an arctic drilling platform is provided wherein various methods and means of interlocking neighboring platform modules are provided. Methods and means for sealing the intersections formed between a plurality of interlocked platform modules are also disclosed. According to further aspects of the invention, improved platform floor plans are provided, and various wellhead cellar layouts and sealing means are also described. Methods and means of enhancing the usefulness of modular storage platforms are disclosed, and a number of support post installation and removal techniques are also provided. Also taught are a variety of methods of adjusting the height and level of an assembled drilling platform, and methods and means of adding extension members useful for extending the length of a support post are also described.

摘要： A pipeline installation and maintenance method and system is disclosed in which a number of interconnectible platform modules are assembled into drilling platforms from which a segmented pipeline route is flexibly installed. Using modified push/pull rigs to carry out a transverse drilling process established between platforms, successive portions of the pipeline are installed such that equipment used to create completed segments is moved down line and re-used in subsequent drilling and installation stages. Further segments of the line are similarly constructed, using one or more of the modified directional drilling techniques and transverse reaming processes disclosed herein. Ultimately, a long series of adjacent pipeline segments are installed along a desired pipeline route, while only minimal and temporary disturbance is caused to associated ground surfaces during installation and maintenance operations.

摘要： A system for and method of limiting and controlling the unintended subsurface release of an exploration or production riser system is provided including one or more means for anchoring the riser or casing stack at one or more pre-determined points upon the length of the riser, and / or on the housing of an associated buoyancy chamber or the like, and / or on a particular portion of the riser as dictated by the operational environment, and / or on an anchor portion secured in the sea floor; and a network of restraining members disposed on the anchoring means. A lower anchoring portion includes one or more anchors disposed in communication with a wellhead, or with the sea floor or below the sea floor mud line, or with a well casing portion. A network of restraining members forms an essentially continuous connection from the buoyancy member portion to said bottom anchor portion. In a particular, though, non- limiting embodiment of the invention, a means for anchoring the system using pairs of anchors disposed at one or more predetermined points along the riser portion of the system is provided. Also disclosed is a variety of means and devices by which a surface vessel or a rig, etc., servicing a subsea well equipped with the present system may absorb or deflect impact forces originating from portions of the system that unexpectedly break free and rush upwards toward the surface vessel or rig.

摘要： A method and system for building modular platform structures from which oil and gas wells are drilled and maintained inludes a plurality of easily transportable, multifunctional platform modules (13) are interconnected on-site to form a unitary platform structure. The interconnected platform modules (13) are elevated above a ground surface on one or more legs (15) coupled to at least one of the platform modules. The elevated, interconnected platform modules (13) support both drilling and production operations in land-based, arctic, inaccessible, near-offshore and environmentally sensitive locations.
