Drass patented SVS enables prolonged ventilation of the DISSUB at extreme depths, removing air toxicity for the safety of the DISSUB personnel and streamlining the rescue operation by avoiding transfer under pressure and decompression of the DISSUB personnel. (DRV) DEEP RESCUE VEHICLE DRASS DRV is a modern, effective and reliable rescue vehicle, remotely operated Further information on Drass SVS is available in FW051-10 and launched from the moon pool. DRASS DRV is capable of the most extended NEW GENERATION HEAVY WORK CLASS ROV endurance in intense weather conditions - operating in very rough seas and connecting to the DISSUB even during extreme angle inclination. Conceived to tackle the tomorrow challenges of deep subsea The DRV moon pool launch offers the highest reliability and safety standards unmanned operations even in extreme sea conditions thanks to the rail guides and protection of a passive cursor. The cursor extends outside the ship keel, protecting the DRV from accidental bumping against the hull. The main wire pulls the DRV gently into the cursor which is conically shaped to connect with the entrance of the DRV frame. Overall description: The heave compensation system keeps the DRV position stable from vessel motion, easing the connection of the DRV with the recovery frame.
