The Indian Navy is looking to procure nine new 25 ton Bollard Pull Tugs to assist naval ships and submarines in berthing and unberthing, turning and manoeuvring in confined waters and harbours. The tugs will also be required for undertaking cold move of naval ships and submarines under refit maintenance within port limits. In addition, they will be required to provide assistance for dry docking and undocking ships and to assist movements in out of the tidal basin. The navy also specifies that such vessels should be capable of moving non self-propelled vessels such as ammunition water fuel barges and lighters within port limits, assist warships during inclement rough weather to prevent accidental damage within port limits, providing afloat fire fighting cover and/or assistance to ships alongside or at anchorage and provide towing assistance to warships. The navy has additionally stipulated that the tugs may be deployed beyond port limits, after suitably augmenting crew strength, for specific duties such as salvage and search & rescue missions. The vessels need to have a life of 30 years. The tug should be able to carry out its functional role up to sea state 4 and operate up to sea-state 6 and survivable as per approved class/IMO norms. The tug should have a SRP (steerable rudder propeller) or an Azimuthing thruster type propulsion system, and be manned by one master, one engineer and 11 crew only.
