  • Subsurface buoy and methods of installing, tying and dynamically stabilizing the same
    Patent number: 6780072
    Abstract: The present invention relates to equipment installed in an intermediary region between a floating production unit at the ocean surface and a wellhead of an oil reservoir on the ocean floor. The equipment, known as a subsurface buoy, is designed to support rigid and flexible production tubes used for the transport of reservoir fluids from the oil well and/or fluids used in support systems for the oil reservoir. Four cylindrical bodies 1, 2, 3, and 4, connected at their extremities, form the body of the subsurface buoy. In each of the vertices of the subsurface buoy, components of a tying and dynamically stabilizing system 13 are rigidly connected.
