  • Apparatuses and methods of deploying and installing subsea equipment
    Patent number: 6752100
    Abstract: The invention describes a cost-effective alternative for deploying and installing subsea equipment using a workboat or other vessel of opportunity. The equipment is not supported directly by the vessel, but is instead supported by one or more buoys below the wave zone. The buoys are controlled by a combination of chain, wire rope, and synthetic line linking it to the workboat. As such, the buoy system described herein decouples vessel motion from the payload by supporting the payload from the buoys below the wave zone. Because the buoys are below the wave action and its associated turbulence, there is little energy and hence little tendency for motion. The result is a stable, inexpensive, maneuverable system capable of servicing large subsea payloads in a wide range of water depths.
