The United States Naval Ship (USNS) Watson is one of the large, medium-speed, roll-on, roll-off (LMSR) ships that have significantly expanded the nation’s sealift capacity. The Watson has a considerable amount of machinery including main engines, generators and cranes that need oil tested on a regular basis to detect potential problems and eliminate the possibility of a catastrophic failure. The test kits used in the past were time-consuming and their accuracy was questionable. The (USNS) Watson is operated by Ocean Shipholdings, Inc. (OSI) under contract to Military Sealift Command.
