Australian Submarine Rescue Vehicle Remora (ASRV Remora) was a submarine rescue vehicle used by the Royal Australian Navy (RAN) between 1995 and 2006. The name comes from the remora, a small fish that can attach itself to larger marine life, and has the backronym "Really Excellent Method of Rescuing Aussies".[1][2]
Remora was constructed by OceanWorks International of North Vancouver, British Columbia for the RAN, based on a diving bell.[1] The Script error: No such module "convert". vehicle was designed to mate with a submarine's escape tower, and could do this even if the submarine had rolled up to 60 degrees from vertical.[1][2] The vehicle can operate at depths over Script error: No such module "convert". and in currents of up to Script error: No such module "convert"., and was intended for use below Script error: No such module "convert".; the maximum safe depth for Submarine Escape Immersion Equipment.[1][3] The submersible carried seven people: an onboard operator and six passengers.[1] Those aboard Remora were kept under about five bars of pressure, and rescued submariners exited into one of two 36-man recompression chambers carried aboard the rescue ship.[1]
Remora could be controlled from a containerised facility aboard the rescue ship, with power, control, and sensors fed through an armoured umbilical cable.[4][5] Twelve personnel make up the surface control complement, with this number supplemented by diving medicine specialists and divers.[5] The entire setup (Remora, control centre, and recompression chambers) could be transported by road or sea, or loaded into C-130 Hercules aircraft.[4][3] Remora could be delivered to anywhere in Australia within 36 hours, and installed on a suitable vessel in another 25 hours.[3] The Defence Maritime Services tender Seahorse Spirit was designated the main tender for Remora, although any vessel with sufficient space to carry and deploy the equipment (Script error: No such module "convert". of deck space, with Script error: No such module "convert". minimum width) could be used.[6][5]
In December 2006, the umbilical cable parted during an exercise off Perth, trapping two men at a depth of Script error: No such module "convert". for 12 hours.[2] The men were rescued, but Remora was not recovered until April 2007.[2] The submersible was sent back to OceanWorks for repairs.[2] Although repairs were completed, Remora did not reenter service as the Det Norske Veritas classification society refused to certify the submersible; the launch and recovery equipment did not meet updated safety standards.[2] As of the end of 2008, Remora was in storage at Henderson, Western Australia.[2] To cover the capability loss, the Department of Defence arranged for the British LR5 submersible to be flown to Australia if submarine rescue was required.[2] In June 2009, LR5 was relocated to Australia on lease.[7]
Remora was the basis for the United States Navy's Submarine Rescue Diving Recompression System.[8]
