ISE Delivers ROV for SNK

ISE delivered a new Remotely Operated Vehicle (ROV) for SNK Ocean Co. Ltd., a Japanese marine services company based out of Tokyo, Japan. SNK has other ISE equipment. The HYSUB ROV - the Hakuyo 150-3000 - is designed to perform several functions including cable burial, salvage, research and survey. It is SNK’s deepest diving ROV, rated to an operational depth of 3000m. It will compliment SNK’s existing HYSUB ROV that operates to depths of 2000m. The vehicle is equipped with four lateral and three vertical thrusters, two manipulators, a full sensor package, and ISE’s customized control system, ACE. The ROV is also equipped with a custom designed jet skid designed by James Adamson for cable burial operations. The ROV’s hydraulic power can be divided into two 75HP circuits when the skid is attached. After locating the cable, the vehicle descends and the jetting legs. A TSS cable skid is used for cable tracking. The forward thrust is 2500 lbs, and the forward speed is 3.7 knots. SNK Ocean Co. Ltd. and ISE have enjoyed a long-standing relationship that extends over 20 years, with ISE delivering SNK’s first ROV in 1991. SNK provides marine vehicles including offshore construction equipment, offshore natural resources investigation, wreck and salvage operations.
