Cheoy Lee recently delivered RT Atlantis, the third of four ART 80-32 Rotor®Tugs, to Kotug International BV. The latest delivery will join the first two (RT ENDEAVOUR and RT DISCOVERY) from the series at Port Hedland in Western Australia where they are on charter to BHP Billiton. The Rotor®tug distinguishes itself from conventional ASD, tractor or Voith designs by using three azimuth propulsion units, oriented in a triangular configuration, with significant separation between the two forward thrusters and single aft drive unit. The maneuverability of this type of tug is superior to conventional designs, and enhanced safety during towing and escort operations is a key attribute. Other benefits include an added level of redundancy with the triple engine and thruster combination and higher bollard pull in all directions. The latest Rotor®tug models are designed exclusively by Robert Allan Ltd. Canada, in conjunction with Rotortug BV who owns the patent. The Cheoy Lee ART 80-32 are built to Lloyds class, with the notation +100A1 Escort Tug, Fire-Fighting Ship 1 (2400m3/h) with WaterSpray. IWS, +LMC, UMS, Coastal Service. Propulsion is by three Caterpillar 3512C engines, each developing 2,365hp, coupled to Schottel SRP3000FP fixed pitch azimuth thrusters via Twin Disc MCD3000-3LD slipping clutches. As the series name implies, the 32m long vessels delivers a bollard pull of over 80 tonnes, both ahead and astern, with a free running speed of 13 knots. Electrical power is from two Caterpillar C6.6 generators, with a third Caterpillar C4.4 unit for harbor service. Sic crew can be accommodated on the vessel, two in single master and engineer cabins. On the main deck and four more in two 2-man cabins on the lower deck. On the bridge deck, a single helm seat slides on rails between Alphatron bridge consoles.
