摘要： A marine operations structure for use in arctic seas having steel/concrete composite ice walls positioned to permit multi-year ice ridges to be broken up with lower vertical forces imposed on the structure than heretofore possible. The structure provides for simultaneous contacting and fracturing of both surface ice floe and multi-year ice ridges by proportioning of the ratio of the annular dimension of a first sloped surface to the radius of the structure within the range of about from 0.15 to 0.30. The structure is fabricated by modular construction techniques which lowers total construction costs. The structure is in the form of a sixteen-sided polygonal sloped walled marine structure with internal ballast tanks for providing gravity founding of the structure on the sea floor. Modular drilling equipment is provided for and supported by the structure for use through two rectangular shaped moon pools extending vertical throughout the central core of the structure. The process for simultaneously contacting and fracturing surface ice floes and ice pressure ridges is set forth along with the processes of installing and deballasting and relocating the structure. Also the process of fabricating the marine operations structure is set forth.

摘要： A different approach to tender assisted drilling which has the flexibility to be used with multiple jack-up rigs, and nearly any type of fixed offshore production platform. A skid base includes distinct capping beam feet and skid-off feet, the former adjustable to capping beam spacing and the latter restricted to support of the skid base upon cantilever beams. A special swivel mechanism and sliding mounting in the capping beam feet, and a vertical jack in the aft skid-off feet, enable the skid base to be transferred to the fixed platform simply by aligning them over the capping beams and depressurizing the skid-off feet. Thus, walking mechanisms may be swivelled and oriented upon the capping beams, notwithstanding relative movement between the jack-up rig and the platform. The skid base is simply walked across from the cantilever beams to the platform. The drill floor package is installed onto the skid base by raising and locking the cantilever beams into alignment with the skid base, while the skid base remains in a floating condition upon the fixed platform, and by skidding the drill floor package atop the skid base. The skid base may then be uncoupled from the cantilever and aligned with the platform using the walking and swivel mechanisms and the sliding mountings of the capping beam feet. Longitudinal and transverse movement abilities of the drill floor permit tender-assist drilling upon a variety of precise locations of the platform, and is readily supported from the jack-up rig with the aid of modular piping.
