Abstract
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.
