Title: Buoyancy plugs for laying offshore pipeline - prevent kinks overloading welds, facilitate stowing during bad weather and recovery
IPC: F16L1/16
Filed: 1977-06-06
Abstract: A pipeline is lowered to the seabed from a surface vessel whilst additional lengths are attached by welding or flange connections to the line already in the water. The wall thickness and the dia. of the pipeline are selected relatively to each other so that when not filled with water, the pipe floats below the surface with a definite degree of buoyancy. If filled with water, the pipe rests solidly on the seabed and resists the forces applied across it by the movement of the water. Hence, during laying, the pipeline is filled with water from the part which is already resting on the seabed under controlled conditions to suit the speed of lowering. The technique can be used for both pipelines laid down in tunnel tubes, and for normal lines for transporting oil or gas, whether or not they have a protective envelope making them heavier. There is no need for underwater welding and the buoyancy given to the sections leaving the ship prevent kinking under their own weight and the imposing of intolerable loads on the welded joints.
