摘要： Deploying an offshore oil and gas production platform comprises placing a buoyant equipment deck on a buoyant pontoon so that elongated legs on the pontoon, each comprising a buoyant float, extend movably through respective openings in the deck. Chains extending from winches on the deck are reeved through fairleads on the pontoon and connected back to the deck. The chains are tightened to secure the deck to the pontoon for conjoint movement to an offshore location. The chains are loosened and the pontoon and leg floats ballasted so that the pontoon and leg floats sink below the floating deck. The chains are then re-tightened until pawls on the leg floats engage the deck. The buoyancy of at least one of the pontoon and leg floats is increased so that the deck is thereby raised above the surface of the water. The chains are connected to mooring lines around an offshore well site, and the raised deck and submerged pontoon are maintained in a selected position over the site with the winches.
摘要翻译：部署海上石油和天然气生产平台包括将漂浮的设备甲板放置在浮力浮筒上，使得浮筒上的细长的腿部（包括浮力浮子）可移动地延伸穿过甲板上的相应开口。从甲板上的绞车延伸的链条通过浮桥上的通道进行连接并连接回甲板。链条紧固以将甲板固定在浮桥上，以便联合移动到离岸位置。链条松动，浮桥和腿部浮球被压载，浮桥和腿部浮动水槽沉没在浮动甲板下面。然后将链条重新拧紧，直到腿部浮起的爪子与甲板接合。浮筒和脚浮体中的至少一个的浮力增加，使得甲板从而升高到水面之上。链条连接到离岸井场周围的系泊线，并且升高的甲板和淹没的浮筒通过绞车在现场保持选定的位置。

摘要： A compliant offshore structure in which stabilization against excessive sway is provided by a resilient pile assemblies. A series of drive piles extend into the ocean floor beneath the base of the structure. Drive piles extend upward to a position proximate a pile attachment location on the structure a spaced distance above the ocean floor. The upper end of each drive pile is secured to the structure at the pile attachment location by a resilient coupling. The resilient coupling permits the structure to move upward and downward a slight distance relative to the substantially rigid drive pile. This accommodates sway of the structure. The resilient coupling biases the structure back to a vertical orientation in response to sway of the structure. In a preferred embodiment the pile attachment location is situated proximate the base of the offshore structure.

摘要： A fatigue-resistant threaded connector for connecting adjacent sections of a tubing string subject to cyclic dynamic stress variations is disclosed. The connector comprises a pin member which is threadedly engageable with a corresponding box member. In its preferred embodiment, the connector is radially preloaded. The connector has tapered threads with a straight load path having substantially no eccentricity. The preferred thread form is a modified buttress thread having a zero (or near zero) degree load flank, a 45 degree stab flank, and a large root radius. Additionally, the thread may include a small stab flank relief to reduce stress concentrations, and a differential between the pitch of the pin threads and the pitch of the box threads to compensate for the Poisson's ratio effect of the radial preload. The connector utilizes an elliptical stress relief groove at the base of the pin threads and elliptical contours on all thickness transitions to reduce peak stresses. The fully assembled and preloaded connector has a maximum stress-concentration-factor of less than 1.5 and its weight is less than 2.5 times the weight of an equivalent length of tubing.
摘要翻译：公开了一种用于连接受到循环动态应力变化的油管柱的相邻部分的耐疲劳螺纹连接器。连接器包括可与相应的箱构件螺纹接合的销构件。在其优选实施例中，连接器径向预加载。连接器具有锥形螺纹，其具有基本上不偏心的直的负载路径。优选的螺纹形式是具有零（或接近零）度载荷侧面，45度刺侧面和大根部半径的修改的支撑螺纹。此外，螺纹可以包括小的尖端侧面浮雕以减少应力集中，以及销螺纹的间距和箱形螺纹的间距之间的差异，以补偿径向预载荷的泊松比效应。连接器在所有厚度过渡处，在销螺纹的基部和椭圆轮廓的基部处使用椭圆应力释放槽，以减少峰值应力。完全组装和预加载的连接器具有小于1.5的最大应力集中系数，其重量小于管等效长度的2.5倍。

摘要： A compliant offshore structure in which the primary restoring force to lateral displacement is provided by elongate flex elements. A gravity base is rigidly secured to the ocean bottom. A tower extends vertically upward from the base to a position above the ocean surface. A work deck is supported atop the tower. The tower is secured to the base by elongate flex elements which are arranged in an array surrounding the central axis of the structure. Each flex element has one end secured to the base and a second end secured to the tower. The flex elements permit the tower to pivot about its lower end, thus providing the tower and deck with a compliant response to environmental forces. The flex elements also support the tower above and free from contact with the base. This eliminates the need for a vertical load bearing joint between the tower and base.
