Coatings Put To Test To Keep Ships Cool

Every Sailor who has made a deployment to the Persian Gulf can agree on one thing: it's blistering hot. At least two out of every three Navy ship deployments are made to high-temperature areas. Sustained operations in searing weather increase stress on both equipment and crew. To help lessen the load on shipboard cooling systems, NAVSEA's Corrosion Control Division (SEA 03M) is testing a new derivative of the anti-stain paints already being tested by the Navy — an anti-stain paint that also absorbs fewer of the sun's rays. This special characteristic is known as Low Solar Absorption (LSA). This coating incorporates LSA and anti-stain properties into the standard topside paint formulation, and is applied in the same manner as the old paint system. The LSA coating is expected to result in interior temperature reductions of at least 10 degrees Fahrenheit. The LSA coating will also help reduce ambient exterior temperatures by reducing solar absorption. USS Fletcher (DD 992), undergoing a maintenance availability at the Pearl Harbor Naval Shipyard, is the first ship to receive the entire LSA paint package — stem to stern, freeboard to superstructure, and decks. The package consists of two different LSA coatings: an anti-stain coating for freeboard and superstructure and a non-skid coating for decks. USS Fletcher leaves the shipyard in a late summer/early fall timeframe.
