Supply, Deployment, and Translation of Hydrophones for Underwater Acoustic Facility

NPL is seeking a solution for the deployment and translation of a set of hydrophones into an underwater acoustic facility. The facility is an underwater acoustic calibration tank consisting of a large wooden vessel (5.5m in diameter and 5m deep) filled with potable water. The calibration activities will be performed with either 2 or 3 hydrophones deployed at the mid-depth point of the vessel. The hydrophones are mounted at the end of carbon fibre poles of minimum size to avoid acoustic reflections. The size and des...
