One of our applicator crews started on the Golden Alaska and sprayed 11,000 sq feet in 48 hours.
Ceramic Insulation Coating on the "Golden Alaska"
Application of 0.080”/2 mm of ceramic insulation coating for anti-condensation, thermal insulation and preventing corrosion under insulation (CUI). Total coverage was 11,000 SF/1,100 square meters in 48 hours by a 6 man crew at Todd Pacific Shipyard in Seattle, WA in March, 2008.
The M/V Golden Alaska is a 305 ft., 3706 gross ton processing vessel that operates in the Bering Sea, along the Aleutian Chain and the North Pacific Ocean. Operating under the mothership concept and supplied with fish by six catcher boats she produces Fillet Blocks, H&G, Mince, Surimi, Pollock Roe and Fishmeal. All products are frozen at sea and off-loaded into freezer containers in port (usually Dutch Harbor, Alaska or Seattle, Washington.
Todd Pacific Shipyard applied 800 gallons of DeltaT Marine insulation coating at at 80mil thickness in the processing space of the Golden Alaska. The owners of Golden Alaska, a catcher processor of the Alaska fishing fleet were pushing Todd Pacific hard to complete all their work so they could get back to work.
The insulation coating replaced wet mineral wool in the fish processing space below the main deck that was constantly awash and subject to high humidity. These conditions render traditional insulation worthless due to high moisture content and accelerate corrosion under insulation that will affect structural integrity.
Substrate surfaces were waterjet blasted to remove loose corrosion and lower finish panels covering the bottom of sidewalls were cut away to eliminate pooling of water. Then a primer coat of International 300, a surface tolerant epoxy was applied.
Todd Pacific’s crew, led by Dan Nichols, focused on providing optimal conditions to apply the water-based ceramic latex coating on the space’s 11,000 square foot surface area. Relying on 30+ years of painting experience on the Seattle waterfront, they provided hot water tubs to warm the coating and used dehumidification equipment to accelerate drying. The coating crew consisted of 3 full time applicators and 2 loaders. The ceramic latex coating was applied in 10 mil coats with a ½ hour break at the end of each coat’s application. On flat surfaces, ceramic insulation coating can be applied at a rate of over 1,000 square feet per hour by one applicator. This application averaged about 2 hours per 10 mil layer over the 48 hour coating time with 40 mils applied each day’s shift.
