The ‘Pilbara Thor’ is the latest of the RAmparts 3200-class tugs to be built from a design by Robert Allan, Vancouver, Canada.
‘Delivered by New Zealand-based Shipco Marine Constructors in December 2008, ‘Pilbara Thor’ is the first of two new terminal support tugs for Australia’s Rio Tinto. The vessel entered service at the Pilbara ore terminal near Dampier, Australia in January. Robert Allan worked closely with the Rio Tinto’s representatives, Trevor Cosh and Associates and Edwards Marine Services to establish the final specification and vessel layout for the demanding service of this 32-metre by 11.6-metre tug. The hull form reflects the double chine form that characterises all Robert Allan designs, with a sweeping “chined” stern. A large escort skeg is fitted forward to enhance the indirect towing capability and to provide enhanced roll stability.
