Tugs & Towing by Jack Gaston

Smit Orders stretched Stan Tug 3509 for Africa

Smit International Gabon SA has awarded a contract to Damen Shipyards Gorinchem for the construction of a new terminal tug. Following a comprehensive tendering process the order was placed for a Damen Stan Tug 3509 for delivery at the end of this year. The vessel will be deployed primarily for local terminal duties on the west coast of Africa and will join a similar vessel completed by Damen four years ago.

Built to comply with Bureau Veritas rules the vessel is basically a Damen Stan Tug 2909 lengthened by adding a 6m centre section. In its final form the tug will have an overall length of 35.26m, a beam o. a. of 8.85 m, a draft of 4.25 m and a displacement of 420 tonnes with empty tanks. The tug will be named Smit Mandji and be equipped for mooring assistance, supply, anchor handling and ocean towing.

Two Caterpillar 3516B TA/A main engines will drive a pair of fixed pitch Promarin propellers (rotating within Van der Giessen nozzles) via Reintjes WAF 872/7.087:1 gearboxes.

The main engines will produce a total of 2950 kW at 1,600rpm to achieve a predicted bollard pull in excess of 52.8 tonnes, with a free running speed of approximately 12.7 knots.

A bow fender will be fitted for pushing purposes and a large clear work deck is provided aft. The twin-drum anchor handling/towing winch will be hydraulically operated and have a line pull of 40 tonnes at 10m/min. One drum will carry 400m of 38 mm steel wire and the other 610m of 48 mm of the same material. For anchor handling work the tug will have a stern roller of 4400 x 1100mm and Karmoy towing pins and forks will be fitted for anchor handling and towing. A Mampaey quick release tow hook, with a safe working load of 65 tonnes, will also be installed.

Smit Mandji will be equipped for fire fighting with a 1,200m 3/hr. Nijhuis HGT fire pump driven by a dedicated Caterpillar 3412C TA diesel engine. A Megator DP20 82ltrs/min dispersant set will be installed. For supply/transfer purposes the tug will be provided with a SIHI ZLKD 50m 3/hr cargo pumps for fuel and freshwater.

Crew accommodation will be fitted out to a comfortably high standard, with air-conditioned living quarters for 12 persons.

A modern navigation and communication outfit will include two Furuno FR-1501 MKII and FR-7062 radars, Plath Navigat X MK1 Model 10 gyrocompass, Plath Naviplot V HSC/GM autopilot, Furuno GP-90 GPS, Furuno LS6100 echosounder, two Sailor RT4822 with DSC VHF radios, Furuno FS-1570 with DSC SSB, two Furuno Felcom 15 Inmarsat C, Furuno NX-500 Navtex and a Furuno FA100 AIS.
