Designed exclusively for Sanmar Shipyards, Robert Allan Ltd (RAL) has introduced the RApport 1900-SX harbour tug, which replaces the previous Sanmar Series, currently numbering 31 units built and delivered since 1995.

The first six vessels of the new design have been completed and deployed to the fleets of Sanmar and Marintug in the Gulf of Izmit and Antalya Port in Turkey. The Gulf of Izmit, located to the east of the Sea of Marmara, is one of the largest port areas in Europe, currently handling an average of 10,000 ships annually.

The 19.3m long RApport 1900-SX is a steel hulled, twin screw harbour tug, for general harbour and coastal towing duties, designed for high performance at a competitive cost. Increased beam provides better stability and there is clear visibility from the wheelhouse in all directions. Conventional twin screw propulsion with twin nozzles and four rudders provides a bollard pull of up to 33t, free running speed of 12 knots and high manoeuvrability. Accommodation houses a crew of four, with two cabins, pantry, mess, washroom with shower. A three-cabin arrangement for a crew of five is available.

The standard propulsion system consists of twin 970kW Caterpillar C32 engines, ZF 3761 6:1 reverse/reduction gears, 175mm stainless steel shafts, and 1880mm 4-bladed propellers in #37 nozzles. Twin high aspect ratio rudders are fitted behind each nozzle.

The engines are fitted with dry exhausts and polished stainless-steel tail pipes. With large aft facing windows in the wheelhouse and low profile funnels the towing equipment and critical areas of the aft deck are visible to the operator. A large shipping hatch located between the funnels provides a convenient removal route for large items of machinery including an entire main engine.

A 45t tow hook is fitted on the aft deck for general towing duties with an electric or hydraulic towing winch available as options. Double pipe bollards are fitted in the bulwarks for mooring, two forward and two aft, and stainless-steel mooring rings in the bulwarks. Fendering is provided to suit each client’s requirements with the standard being 300 mm D-fenders at the sheer and vertical W-fenders around the bow. A push knee can be fitted on the bow if needed. The mast can be ordered as a folding type. Heavy duty lifting lugs for a three-point hoisting tackle are standard equipment.
