Fremgangsmåte for beskyttelse av undervannsledninger fra progressiv buling, spesielt for å stoppe forplantningen av en gaffelformet eller aksiell bue

摘要

The invention relates to a method of protecting an underwater conduit (100) against collapse, due to high hydrostatic pressures At least one bracing device (106) is applied around the external circumference of the conduit so as to define locally a region of increased wall thickness, and the internal surface of the device is bonded to the external surface of the conduit. This inhibits separation of the two surfaces and thereby helps to prevent collapse of the conduit.
