RatShip is a dedicated submarine rescue intervention ship to perform subsea and surface search and rescue missions, open sea towing operations and fire fighting up to and including sea state 6. She is equipped with a twin controlled pitch propeller (CPP) system, aft and bow tunnel thrusters and a retractable thruster, which allows high manoeuvrability and accurate position keeping capability. The RatShip is a monohull vessel with 68m overall lengths, 14m beams and 4m draughts. With a displacement of around 1,95o tons she will have enough space for 104 personnel. She can attain the same speed and endurance levels of the MoShip. The RatShips will be equipped with a locally designed and developed Gelibolu ROV and an ADS for underwater rescue missions but they can be used in torpedo firing exercises as a target ship and picking up/recovering torpedoes from the sea during the torpedo firing exercises. In towing missions the RatShip shall tow a minimum 25.ooo tons vessel at minimum speed of 4 knots. Her additional roles include subsea welding up to 1oom, fire fighting (with 5 water/foam monitors), support for submarine rescue operations and offshore towing operations. The RatShip has 46om2 clear aft deck and a 12 tons capacity hydraulic/telescopic crane.
