Method for repairing a damaged pipe laid on deep sea beds

摘要

A method is disclosed for repairing a damaged pipe laid on deep sea beds, said method substantially comprising the step of joining a central pipe stub between the ends of the two adjoining pipe portions, such operation being performed directly on the sea bed rather than on the pipe-laying barge. Special coupling sleeves are provided at both ends of the central pipe stub, said sleeves being received in a watertight manner on the two pipe terminal portions, by clamping said sleeves thereon. Apparatus and tools for carrying out said method are described in great detail.
