The life of marine structures can be extended when proper measures are taken to protect surfaces in contact with seawater. Applying protective coatings is the conventionally accepted method of protecting steel marine structures from corrosion attack. Since marine structures are subject to salt, air, or water exposure, the coating systems used are much more sophisticated than ordinary systems for inland steel structures.
Many references are available for applying marine structure protective coatings above the water line. Two excellent references are:
• NAVFAC M0-104 - Maintenance of Waterfront Facilities (scheduled for revision in 1997)
• NAVFAC MO-llO - Paints and Protective Coatings
The following discussion is concerned only with die application of protective coatings below the high water line.
