Submarine Deep Rescue Ship (MOSHIP-TR1)

MOSHIP-TR1 is a monohull vessel, designed to perform subsea and surface rescue missions including heavy seas, equipped with redundant diesel-electric propulsion system allowing flexible power share and strong position keeping, conforming naval norms/standards and classification rules. Project contracts with Istanbul Naval Shipbuilding Savunma Sanayi Müstesarligi TIC.a.þ., and San. was signed on October 28, 2011 between.

The MoShip and RatShip Project tender was launched on May 2008 and following a year-long proposal evaluation process, contractual negotiations with Istanbul Shipyard, the winner of the tender as per Defence Industry Executive Committee decision dated June 15, 2010, were started in June 2010. On October 28, 2011, the Undersecretariat for Defence Industries (SSM) of Turkey awarded two separate contracts to Istanbul Shipyard to construct and deliver one Submarine Rescue Mother Ship (MoShip) and two Rescue and Towing Ships to meet a Turkish Naval Forces Command (TNFC) requirement. To be procured under two separate contracts, the MoShip will be delivered to the Turkish Navy in 31st months and the RatShips will be delivered in 37th and 39th months respectively following the advance payments.

MoShip is dedicated submarine rescue mother ship designed to perform subsea and surface search and rescue missions up to and including sea state 6. The ship will also able to perform rescue and towing operations for broken-down, wrecked or aground vessels. Equipped with diesel-electric propulsion system and bow thrusters allowing flexible power share and high-qualified position keeping (she can keep her position at 4 knots and in sea state 4 conditions), she conforms naval norms, standards and classification rules to its unique off-shore design. MoShip will be able to detect distressed submarines, to provide life support including ventilation and pod posting and to rescue submarine crew from depths up to 6oo meters and transferring them under pressure up to 5 Bar (in pressure chamber). She will have the necessary means and capabilities to rescue submarine crew in maximum 72 hours.

The MoShip is a monohull vessel with 9om overall length, 18m beam and 5m draught. With a displacement of around 4.1oo tons she will have enough space for 131 personnel, of which 89 will be ship crew and 32 will be rescue personnel. She has a maximum continuous speed of 18 knots and an endurance of 4,5oonm at an economical speed of 14 knots. MoShip has the necessary equipment and heli-deck, (acting as MedEvac station) to operate (take-off and landing) a 12-ton general-purpose helicopter in up to sea state 4. She has a 65om2 clear aft deck area for the deployment and use of NATO NSRS, US SRDRS, ADS, Personnel Transfer Capsule (PTC) and Submarine Rescue Chamber (SRC). For the deployment and recovery of rescue systems there is a 35 tons capacity hydraulic/telescopic crane in the aft deck.

The SNR-MOSHIP design was a dedicated submarine rescue mother ship designed to perform subsea and surface search and rescue missions in various sea conditions. Equipped with diesel-electric propulsion system allowing flexible power share and high qualified position keeping, she conforms naval norms, standards and classification rules to its unique off-shore design. SNR-MOSHIP is capable of detecting distressed submarines, providing life support including ventilation and pod posting, evacuating her crew up to 600 meters of depth and transferring them under pressure up to 5 Bar for the first time in years of submarines’ having been used. SNR-MOSHIP has a maximum continuous speed of 18 knots and an endurance range of 4500 nautical miles at an economical speed of 14 knots for the roles and capabilities with her built in and necessarily loaded submarine rescue equipments/ systems onboard.
