摘要： A riser angle positioning system and process provides information for dynamically positioning a floating vessel (10) having a riser (12) extending to a wellhead on the ocean floor. The system comprises an acoustic system (46) for generating acoustic data signals representing the position of the vessel with respect to the wellhead, top (42) and bottom (44) riser inclinometers for generating respective sensor signals indicating angles of deflection of the riser at the top and bottom, respectively, thereof, and a processor (40) responsive to the acoustic data signals and the sensor signals for generating positioning information. The riser angle positioning system and process serve as a backup system and method for checking the acoustic data for large errors, and additionally provide the sole position determining system and method in case of acoustic black-out. The riser angle positioning system and process have two alternative modes of operation: a simulator mode during which the vessel position is calculated from data read from a dynamic positioning system magnetic tape log, and a real time mode during which data is read directly from analog-to-digital converters associated with the top (42) and bottom (44) inclinometers and the acoustic system (46).

摘要： Offshore, gravity base, jack-up platform comprising a deck (22), a gravity base (24), and one or more legs (26) interconnecting the deck and base. The gravity base comprises a generally polygonal shaped, monolithic hull structure (28) with reaction members (30) extending downwardly from the hull to penetrate the waterbed and react to vertical and lateral loads imposed upon the platform while maintaining the gravity hull in a posture elevated above the surface of the waterbed. A method aspect of the invention includes the steps of towing a gravity base, jack-up platform, as a unit, to a preselected offshore site floating upon the gravity hull. During the towing operation, the deck is mounted adjacent the gravity base with leg or legs projecting through the deck. At a preselected offshore station ballast is added to the gravity base and the platform descends slightly to a posture where the platform is buoyantly supported by the deck. The base is then jacked down toward the seabed and the platform is laterally brought onto station. Ballast is then added to the deck and the reaction members are penetrated into the waterbed to operational soil refusal. Ballast is then ejected from the deck and the deck is jacked to an operational elevation above a predetermined statistical wave crest height.
摘要翻译：离岸，重力基座，自升式平台包括甲板（22），重力基座（24）以及连接甲板和底座的一个或多个腿部（26）。重力底座包括大致多边形的整体式船体结构（28），其中反作用构件（30）从船体向下延伸以穿透水床并对施加在平台上的垂直和横向载荷作出反应，同时将重力船体保持在升高的姿势在水面的上方。本发明的方法方面包括将重力基座，自升式平台作为一个单元牵引到漂浮在重力船体上的预选离岸站点的步骤。在牵引作业期间，甲板安装在重力基座附近，腿部或腿部穿过甲板突出。在预选的海上工作站，重力基座上添加压载物，平台稍微下降到平台由甲板浮力支撑的姿势。然后将基座朝向海底向下压，并将平台横向带到站台上。然后将压载物加入到甲板中，并且反应构件被渗透到水床中以防止可操作的土壤被拒绝。然后将压载物从甲板上弹出，甲板被提升到高于预定的统计波峰高度的操作高度。

摘要： This invention relates to improvements in auxiliary vessels of the type used to handle the anchors, buoys, etc., used in mooring large ships such as offshore drilling vessels. The improvement comprises a bridge structure elevated above, and movable longitudinally of, the deck of the anchor handling vessel. The bridge structure includes an anti-friction support for a winch line and, when positioned near the stern of the vessel, greatly reduces the forces necessary for breaking an anchor or similar object over the stern and onto the deck of the vessel. In the preferred form, the bridge structure also mounts a powered winch or bridge crane movable transversely of the bridge which may be used for moving anchors to other cargo about the deck. This abstract is not to be construed in any way to describe or limit the invention set forth below.
摘要翻译：本发明涉及用于处理大型船舶如海上钻井船舶的锚泊，浮标等类型的辅助船舶的改进。该改进包括在锚处理容器的甲板上方并且可纵向移动的桥梁结构。桥梁结构包括用于绞车线的抗摩擦支撑件，并且当定位在船舶船尾附近时，大大减少了将船锚上的锚栓或类似物体破坏到船尾的甲板上所需的力。在优选的形式中，桥梁结构还安装了可以横向于桥梁移动的动力绞盘或桥式起重机，其可以用于将锚定件移动到围绕甲板的其他货物。本摘要不应以任何方式解释为描述或限制下文阐述的发明。
