The contract between GRSE and NPOL for the ARS was signed in October 2024. The 93 m long and 18 m wide ARS will be a very advanced platform, that will have a complement of 120 personnel and will be capable of speeds ranging from 4 knots to 12 knots. At top speed, the ship will have an endurance of 30 days or 4,500 nautical miles in a single mission.
The capabilities of the ARS will include deployment, towing and retrieval of the various equipment such as acoustic modules, carrying out temporal and/or spatial high-resolution surveys of sound velocity profiles and collection of ocean tides/current information to be used for survey optimization, design of underwater moorings and offshore deployments.
The research vessel will also carry out meteorological surveys to understand the influence of atmospheric parameters in sound propagation studies and undertake shallow water acoustic reverberation studies. It will also be capable of launching, mooring and maintaining standalone buoys and collecting data from them. Its wide speed range will allow the ship to operate at multiple speed regimes to carry out acoustic systems trials, while maintaining silence.
