Record Marine Contract For Voith

Voith Schneider Propellers provide high bollard pull for harbor towage

Posted on August 25, 2014

South Africa’s Transnet National Ports Authority has ordered nine Voith Water Tractors (VWT) for use in several ports across the country. This is the largest order in the history of Voith marine technology, the company said.

The VWTs will be built by South African Shipyards in Durban over the next 42 months. Eight of the tugs will be identical with a length of 31 m and a beam of 12.5 m. Propelled by two Voith Schneider Propellers (VSP) 32R5/265-2, each providing 2650 kW, the vessels will have a bollard pull of 63.5 tonnes. The VWTs will be utilized for harbor towage in the ports of Saldanha Bay, Port Elizabeth, Durban and Richard’s Bay.

Another VWT will achieve a bollard pull of more than 90.7 tonnes and will be one of the strongest ever equipped, Voith said. Propelled by two VSP 36R6EC/285-2, each providing 3900 kW of power, the vessel will measure 37.1 m in length with a beam of 13.5 m.

Voith’s scope of supply includes two turbo couplings and two Renk couplings for each VWT. The eight identical VWTs will get a mechanical control system, while the single 37.1 m VWT will be equipped with a Voith electronic steering system. These components are to be delivered between 2015 and 2017.
