    • A diverless flowline connection system for connecting a flowline to a subsea wellhead or other subsea structure. The diverless flowline connection system is used with a remotely operated vehicle. The diverless flowline connection system includes a frame assembly including clamping arms for mounting the frame assembly to the flowline. A pair of winches are mounted to the frame assembly. Each winch includes a winch line for attachment to the wellhead to which the flowline is to be connected. Each winch is independently controlled so that the lateral position of the flowline may be variously adjusted by controlling each of the winches. The diverless flowline connection system is of modular design to accommodate a wide variety of flowline diameters. The connection system can also be used to pull from the wellhead. Winch line guillotines are provided for severing the winch lines and the clamping arms release the flowline in the event of hydraulic system failure.
    • 用于将流线连接到海底井口或其他海底结构的不连续流线连接系统。 无级流线连接系统与遥控车辆一起使用。 不连续流线连接系统包括框架组件,该框架组件包括用于将框架组件安装到流动管线的夹持臂。 一对绞车安装在框架组件上。 每个绞车包括一个连接到流线连接的井口的绞车线。 每个绞盘被独立地控制,使得可以通过控制每个绞盘来不同地调节流线的横向位置。 不连续流线连接系统采用模块化设计,适应各种流线直径。 连接系统也可用于从井口拉出。 提供绞车线路断头用于切断绞车线,并且在液压系统故障的情况下夹紧臂释放流路。
