COPPER ALLOYS IN MARINE ENVIRONMENTS TODAY AND TOMORROW

The International Copper Research Association (INCRA) maintains an active R & D programme on marine matters and the last 10 to 20 years have seen the development of major new application areas for copper alloys in the offshore oil and gas industries and in desalination plant. General information is given on copper alloys of marine interest, in particular aluminium bronzes and the copper/nickel alloys and their resistance to corrosion and fouling. Applications of copper alloys are discussed, including ships' condenser tubing (some comparisons with titanium and stainless tubing are made), tubing for multi-stage flash desalination plant, seawater piping systems and associated pumps and fittings, and ships' propellers (for which nickel-aluminium bronze now dominates the market). Further applications of copper alloys are discussed, including the use of "solid" copper/nickel and of copper/nickel-clad steel for hulls; information is given on the welding of the sheathing to the steel, on the attachment of copper/nickel sheet to small areas of large hulls, and on various studies on these hull applications. Copper/nickel sheathing of offshore jacket structures, including the Exxon and other studies, is considered in some detail (see also Abstract No.67,809 March 1986). Other applications discussed are seawater intakes and diversion screens at coastal power-stations, and fish-farming cages.
