Sanmar Shipyards trials new tug

Sanmar Shipyards completed the first sea trials of Robert Allan Ltd’s latest tug design in late May.

The steel twin screw harbour tug has increased beam for better stability. Conventional twin screw propulsion with twin nozzles and four rudders provide a bollard pull of 21 tonnes and a top speed of 11.5 knots.

Gökçay is 16.3 metres long and 7.4 metres wide with a 2.7-metre draught.

The propulsion system consists of twin 650kW Caterpillar C18 engines, Reintjes 5.5:1 reverse/reduction gears, 120mm stainless steel shafts, and 1,450mm five-bladed propellers in #37 nozzles.Twin high aspect ratio rudders are fitted behind each nozzle.

The fuel system is a simple two-tank arrangement with wing tanks port and starboard, centrally located to have minimal effect on trim as they are drawn down.

The engines are fitted with dry exhausts with polished stainless steel tail pipes. With large aft facing windows in the wheelhouse and low profile funnels the towing equipment and most of the aft deck is visible to the operator.
