A new azimuth stern drive tug has been designed and built for high manoeuvrability in Singapore ports.
Cheoy Lee Shipyards has built a Z-Tech 5000 tug with an entirely new deckhouse and wheelhouse design for harbour and terminal operations. Polaris was designed by Robert Allan and will be operated by PSA Marine.
It is the first of two Z-Tech 5000 tugs that Cheoy Lee has built for PSA Marine. A sister tug has also been constructed for South China Towing of Hong Kong. These are expected to be delivered in the next two months.
Polaris has a bollard pull of 50 tonnes and a free running speed of 12.5 knots. It has an overall length of 27.4 m, beam of 11.5 m and draught of 5.03 m.
This Z-Tech tug has a pair of Yanmar 6EY26W diesel engines, each delivering 1,550 kW at 750 rpm, driving two Schottel SRP 360 fixed pitch azimuth thrusters.
Electrical power comes from two Perkins diesel-driven Stamford 90-kW generating sets. These gensets help drive MacGregor towing and anchor winches, and a Palfinger folding knuckle-boom crane on the deck.
Crew accommodation is on the main deck, with single cabins for the captain and chief engineer and a couple of two-man crew cabins for a total complement of six. The crew mess and pantry are on the lower deck.
