摘要： A deep draft semi submersible structure wherein the semi-submersible has a center of gravity below its center of buoyancy and the structure is a floating vessel with at least three vertically oriented buoyant columns. Each of the vertically oriented buoyant columns have at least one ballasted compartment and the columns are spaced apart at a sufficient distance to reduce vortex induced vibration amplitude. There are at least two connecting structural sealed trusses connected to the columns below sea level, they are positioned to minimize hydrodynamic wave action on the trusses and to transfer shear loads between the columns while remaining transparent to wave and ocean current motion.

摘要： An offshore construction system comprises a work module support vessel having a ballast-down mode, in which a deck of the vessel is submerged below the water surface, and a ballast-up mode, in which the deck is disposed above the water surface. The system further comprises an independently floatable, pontoon-supported work module carried on the deck of the support vessel. The system also includes a draw connected between the work module and the work module support vessel. The draw has a draw-over mode, in which the work module is drawn over the deck of the support vessel, and a remove mode, in which the work module is removed from the deck.

摘要： An apparatus and method for the installation of a deck on an offshore substructure. The invention is particularly useful with a floating substructure. Two independent pontoons each have two columns spaced apart from each other that extend upwardly from the pontoons. On each pontoon, a support beam attached to the columns spans the space between the columns. Each pontoon is provided with ballast tanks that allow the pontoons to be selectively ballasted or de-ballasted to control pontoon depth for receiving a deck or installing a deck on an offshore substructure. The pontoons may be ballasted down during transit of the deck such that the main body portion of the pontoons is below significant wave action and the columns present a relatively small water plane area. The pontoons allow the deck to be placed directly above the offshore substructure. For a floating substructure, the pontoons are ballasted while the floating substructure is simultaneously de-ballasted to transfer the deck to the floating substructure.
摘要翻译： 一种用于在海上子结构上安装甲板的装置和方法。 本发明对于浮动子结构特别有用。 两个独立的浮筒各自具有彼此间隔开的两列，从浮体向上延伸。 在每个浮筒上，连接到柱的支撑梁横跨柱之间的空间。 每个浮筒都设有压载舱，允许浮船被选择性地压载或卸载，以控制浮桥深度用于接收甲板或在海底子结构上安装甲板。 在甲板运输过程中，浮船可能被压载，使得浮船的主体部分低于显着的波浪作用，并且柱呈现相对较小的水平面积。 浮桥允许甲板直接放置在离岸子结构的正上方。 对于浮动子结构，浮筒被压载，而浮动底座同时被压载以将甲板转移到浮动底座。

摘要： A dynamically positioned loading buoy for transferring liquid from an offshore structure to a tanker. The loading buoy is a floating hull. The hull is provided with thrusters that are used to position the loading buoy and tanker in a safe position relative to the offshore structure. The use of thrusters on the loading buoy eliminates the need for anchors and mooring lines for the loading buoy. The transfer hose used to transfer oil between the offshore structure and the loading buoy may be stored on the loading buoy or the offshore structure. The transfer hose used to transfer oil between the loading buoy and the tanker is stored on a reel on the loading buoy.

摘要： A marine riser system is provided which extends between a floating offshore platform and well means in a seabed formation and which has riser end portions connected in novel manner to the floating platform and to wellhead structure at the well hole. Each end portion of the riser is adapted to yield axially, laterally, and rotatively during movement of the riser relative to the platform and to the wellhead structure. Each end portion of the riser is provided with fulcrum or pivot contacts with hawse pipe carried by the platform and with hawse pipe or casing means provided in the wellhead structure. Bending stresses at the riser end portions are reduced at the platform and at the wellhead structure.
