摘要： A method for building and assembling an offshore platform whose normal draft exceeds the depth of waterways between the building site and use location of the platform. The hull and deck of the platform are built separately in a shallow graving dock. The deck is then elevated, the graving dock partially flooded and the hull floated into position and mated to the deck. A modified form of the invention is the building of the hull and deck as a single structure and use of the barge to support a portion of the weight of the platform. The graving dock is then flooded to maximum depth, a barge is floated under the deck and ballasted down to a select draft. The barge is attached to the deck and then deballasted to partially support the platform structure and reduce its overall draft.

摘要： A mudline tubing hanger is disclosed in which the tubing hanger is provided as an integral part of the tubing string and is set within the casing by an hydraulic setting mechanism driven through an external control line and actuated by a wireline shifted sleeve. Further manipulation of the sleeve isolates the setting mechanism from the tubing and external control line, establishing a chemical injection conduit with access to the tubing bore through the external control line.

摘要： Operators of submerged remotely operated vehicles (R.O.V.)'s must typically view the subsea environment by use of a submerged television camera carried by the R.O.V. Often no part of the vehicle is visible to the operator to give him a natural indication of the direction in which the camera is facing with respect to the vehicle. The apparatus of the present invention generates an artificial "crosshair" on his television viewing screen representing a selected reference axis of the vehicle. This not only reduces directional disorientation of the operator but also gives him a line of sight, independent of camera direction, which he can use to establish the azimuth of subsea features with respect to the vehicle's compass.
摘要翻译：淹没式遥控车辆的操作员（R.O.V。）必须通过使用由R.O.V.携带的淹没式电视机来观看海底环境。通常，车辆的任何部分对于操作者而言是可见的，以便给出相机相对于车辆面向的方向的自然指示。本发明的装置在他的电视观看屏幕上产生代表车辆的选定参考轴的人造“十字准线”。这不仅减少了操作者的方向定向障碍，而且还给出了他的视线，不考虑摄像机方向，他可以使用它来确定相对于车辆指南针的海底特征的方位角。

摘要： A method of replacing a corroded well conductor positioned in an oil production platform at an offshore location. After shutting in or killing the well, the wellhead is removed and the sections of the casing and tubing strings within the well conductor above the mud line are backed off and removed. The damaged well conductor is cut off above the mud line leaving a stub to which the lower end of a new section of well conductor is connected and bonded by means of a novel connector. Communication between the old and new sections of well conductor is established and the casing and tubing sections are re-installed in the new well conductor and the wellhead is closed.

摘要： A method is disclosed for redeploying an offshore platform structure from a first site to a second sight of different water depth in which the connection is released between a subsea jacket base and a plurality of piles which are anchored in the ocean floor at the first site. The offshore platform structure is vertically raised by pumping air into a tank member at the top of the subsea jacket base and the surface tower which is supported upon subsea jacket base is reworked while the jacket base is vertically raised. This operation is less difficult than attempting operations offshore on a horizontally disposed surface tower. The offshore platform structure is transported to the second site and the tank member is ballasted to vertically lower the offshore platform to the second site where it is installed.
