Abstract
The covering, comprises anti-fouling metal sheeting (13, 13', 20) which is adapted to enclose the surface (11) of a sub sea structure, and which has corrugations (14). The sheeting is in the form of a strip (13) which is transversely corrugated and is adapted to be spirally wound onto the structure. It is copper or copper-nickel. The process for applying the covering (13, 13', 20) to a tubular sub sea structure (11) comprises the steps of coating the surface to be protected with an elastomeric anti-corrosion material, applying the sheeting (13, 13', 20) of anti-fouling metal to the elastomeric material to enclose the structure to be protected, applying a pressure of the area of the sheeting to provide a restricting force thereto and vulcanising the elastomeric material. As the sheeting is corrugated the corrugations (14) allow movement of and changes in the circumference of the elastomeric coating to be accomodated during and after the vulcanisation process without undue stress on the bond between the coating (12) and the metallic covering (13, 13', 20). The sheeting (13, 13', 20) is corrugated such that the corrugations (14) extend longitudinally or substantially longitudinally of the structure (10). The sheeting may be in the form of several individual strips wound transversely onto the structure. The anti-corrosion material may be an epoxy resin which is cured chemically after the metallic sheeting has been wound onto the structure. The structure to be protected is normally an offshore structure but may be a structure for use in deeper waters.
