44 AUGUST 2017 MATERIALS PERFORMANCE NACE INTERNATIONAL: VOL. 56, NO. 8 COATINGS & LININGS ESSENTIALS Continued on page 46 Recoated Ferry Freed by Shipyard As a scope, blasting and coating a car and passenger ferry might not sound like a chal- lenging endeavor. But for Puglia Engineer- ing (Bellingham, Washington), doing busi- ness as Fairhaven Shipyard with an 80- to 200-person yard, the details of the M/V Kaleetan project were complex. e 382-ft (116-m) long project included coating work on railings, bulkheads, decks, and rescue boat "pockets." e recoat was to be done on steel and aluminum sub- strates. ere was electrical and steel work, including a variety of tests. ey had to work 24 hours a day, seven days a week, and they also had to overcome challenges with acquiring the amount of materials neces- sary. As if that wasn't enough, they had ex- actly 92 days to complete the project. "We're a full-service shipyard," says Dale Lockwood, senior project manager. ey had the skills to complete the project, but could they overcome the choppy seas ahead? e M/V Kaleetan, which means "arrow" in Chinook, was originally built in San Diego in 1967. To bring it back to its former glory, the crew (averaging 100 to 125 peo- ple) started with preparation. After estab- lishing blast and paint zones, they pro- tected the wiring from grit blasting and overspray. ey zoned and sealed the area and then covered the wiring with ~10 mi (16 km) of rubber strips. Only once covered could the blasting crew come in to work. Working in 100-ft (30-m) long sections, the Fairhaven Shipyard crew blasted to NACE No. 2/SSPC-SP 10, "Near-White Metal Blast Cleaning." ey wore blast hoods with fresh air and used four 8-ton (7,258 kg) blast kegs at 1,800 cfm (51 m 3 /min). Each of the blast kegs had four hoses. On the steel sub- strates, they used 36-grit copper slag. On the aluminum substrates, which included part of the Texas deck around the pilot- house and crew houses, the crew used 30/60 garnet. In areas where the blast hoses couldn't reach, the 25-person blasting crew used power tools to achieve SSPC-SP 11, "Power Tool Cleaning to Bare Metal." The M/V Kaleetan.
