The third tug built in Turkey by Sanmar Shipyards to the TRAktor 2500-SX design by Robert Allan Ltd (RAL) of Canada has commenced operations in London for Svitzer.

The tug, named Svitzer Meridian, is the second TRAktor 2500-SX in Svitzer’s fleet and is the third of this new class of tugs to be delivered by Sanmar to international clients in just over four months.

Above the waterline, this class of tugs feature a raised half foc’sle to provide an enhanced standard of sea-keeping when working in exposed waters. Below the waterline, the hull form and appendage configuration were selected after extensive physical model testing and CFD simulations in order to achieve an optimal balance between controllability, manoeuvrability, fuel efficiency, and roll dampening. On the stern, the simple but extremely effective StRAke stabilizers are fitted. These stabilizers were developed by Voith and RAL to improve tractor tug directional stability allowing for a reduced size skeg and thereby improving manoeuvrability and fuel efficiency. The comprehensive research and development that went in to the design has been paying dividends as all reports received so far regarding the handling and manoeuvrability of the TRAktor 2500-SX design have been extremely positive.

The 25m long tug was constructed to ABS Class requirements with notation ✠ A1, Towing Vessel, Fire Fighting Vessel Class 1, ✠ AMS, ✠ ABCU, IHM, BP (71.5MT), UWILD, QR, Unrestricted Service

Main propulsion comprises a pair of CAT 3516C diesel engines, each rated 2100 bkW at 1600 rpm, and driving Rolls-Royce US 255 FP Z-drive units with 2.6 m diameter fixed pitch propellers. Auxiliary power consists of two identical CAT C4.4 diesel gen-sets, each with a power output of 99 ekW at 1500 rpm.

On trials the Svitzer Meridian achieved over 12.5 knots ahead and 12 knots astern with a bollard pull of 71.5 tonnes.
