Bozcay 01

(VANCOUVER, British Columbia) — Designed exclusively for Sanmar Shipyards, the Robert Allan Ltd. RApport 1900-SX harbor tug replaces the Sanmar Series which currently consists of 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, has been named one of the largest port cities in Europe. It is currently handling an average of 10,000 ships annually in its ports.

The RApport 1900-SX is a steel-hulled, twin-screw harbor tug designed for high performance at a competitive cost. Increased beam provides better stability and visibility from the wheelhouse is excellent in all directions. Conventional twin screw propulsion with twin nozzles and four rudders provide a bollard pull of up to 33 tonnes and excellent maneuverability. There are overnight accommodations in the forecastle for a crew of four including two cabins, pantry, mess, washroom with shower. A three-cabin arrangement for a crew of five is also available.

The standard propulsion system consists of twin 970-kW Caterpillar C32 engines, ZF 3761 6:1 reverse/reduction gears, 175-mm stainless-steel shafts, and 1,880-mm four-bladed propellers in No. 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 45-tonne 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.
