摘要: A riser guide and support mechanism for a floating vessel, and particularly a spar type structure, where the buoyancy can stem extends nearly the entire length of the floating vessel. A riser centralizing element is provided on the riser near the lower end of the buoyancy guide stem. Riser bend limiting elements are positioned on the riser so as to extend above and below the riser centralizing element. Since the buoyancy cans and buoyancy can stem are not required to rotate relative to the stem guides on the floating vessel, the stem guides can be formed from pipe sections that provide a much larger bearing area than is customary.
摘要翻译: 用于浮动容器,特别是翼梁式结构的立管引导件和支撑机构,其中浮力可以在其浮动容器的整个长度上延伸。 提升管集中元件设置在靠近浮力导向杆下端的提升管上。 立管弯曲限制元件定位在提升管上,以便在提升管集中元件的上方和下方延伸。 由于不需要相对于浮动容器上的杆引导件旋转的浮力罐和浮力杆,所以杆引导件可以由提供比常规更大的承载面积的管段形成。

摘要: A subsea hydraulic control module that is totally enclosed such that the hydraulic fluid does not contact the seawater. The majority of the power for the module comes from the hydrostatic pressure of the sea itself. Two oil-over-seawater actuators each have an internal piston that separates the oil from the seawater. Each actuator is provided with two solenoid valves that control the flow of seawater. A fluid line and one solenoid valve on the seawater side of each actuator is in fluid communication with a seawater recovery reservoir. These two valves are also in fluid communication with each other through a common fluid line to the seawater reservoir. The remaining solenoid valve on the seawater side of each actuator may be selectively opened or closed to the ambient seawater. A hydraulic line on the oil side of each actuator is in fluid communication with the equipment to be controlled. The hydraulic lines from each actuator enter the equipment to be controlled on opposite sides of the equipment to allow control of the equipment. The solenoid valves are opened and closed in selected combinations to open, close, or maintain the equipment in selected operating positions.
摘要翻译: 完全封闭的水下液压控制模块,使液压油不接触海水。 模块的大部分功率来自海洋本身的静水压力。 两个油过海运动器都具有将油与海水分离的内部活塞。 每个执行器都配有两个控制海水流量的电磁阀。 每个致动器的海水侧的流体管线和一个电磁阀与海水回收槽流体连通。 这两个阀也通过与海水储存器的公共流体管线彼此流体连通。 每个致动器的海水侧上的剩余电磁阀可以选择性地打开或关闭到环境海水。 每个致动器的油面上的液压管线与要控制的设备流体连通。 来自每个执行器的液压管路进入设备的对面,以控制设备。 电磁阀以选定的组合打开和关闭,以将设备打开,关闭或维持在选定的操作位置。
