CARGO AND BALLAST TANK PITTING REPAIRS WITH CIBA-GEIGY WRP COMPOUNDS

Erosion and corrosion damage to tank bottoms is a major problem in ship repair and maintenance. The marine industry has utilized epoxy or modified epoxy coatings and clad welding with marginal success. Some of the limitations of both approaches are described, as is a test program begun by Ciba-Geigy with Keystone Shipping Company to find a more cost effective and permanent solution. The mechanism of adhesive failure in pit repairs done with epoxy-based products is discussed and the success of Ceramic-Filled Paste and WearCoat in protecting tanks is analyzed. The resistance of both to chemical environments common to the industry is tabulated and ideas are offered on dispensing techniques to improve the repair costs and procedures, and on future technology.
