Next Generation of RAmparts Tugs for SAAM

Chilean maritime services and logistics company SAAM S.A. has signed a contract with naval architecture firm Robert Allan Ltd. for a new generation of RAmparts 2400-W Class tugs.

Ship-handling is performed over the bow using a split drum hawser winch. The compact tugs, which will also provide firefighting capability, include accommodation for a crew of six in two single rooms and two double rooms.

The design complies with ABS Requirements for the following notations: +A1, E, +AMS, Towing Vessel, UWILD, Fire-fighting Vessel Class 1.
