New Additions to the Survey Vessel Fleet
eTrac has purchased its 8th and 9th survey vessels. The first, an aluminum 21′ Thunderjet. The vessel’s first project is to support a dive operation with a local dive firm in support of a debris removal operation. Divers were positioned with GPS and motion sensor, coupled to a USBL and a Beacon device attached to the diver backup tank. The survey craft worked alongside the dive vessel and provided remote display to the dive tender on the vessel. A scanning sonar was used to confirm positions and multibeam sonar imagery was overlaid in the positioning software to assist real-time decision making during the dive operation.
The second, the S/V Taku, a 33′ Armstrong Catamaran. Taku has been used on multiple projects in the Bay since its arrival including towing an Edge Tech sub-bottom-profiler for cable laying projects.
