Oil wells in the North Sea and the North Atlantic are still bubbling with Black Gold. With two new high-performance Voith Water Tractors, the harbor authority of the Shetland Isles (Shetland Island Council) is set to widen its opportunities and will soon be able to unload even larger oil tankers in the harbor of Sullom Voe at affordable cost. In spring 2010, the two new vessels will enter service at the most northern point of Scotland. The two escort vessels will be built in Spain by Union Naval Valencia. With 77 tons bollard pull ahead and 71 tons bollard pull astern, they are in the highest output class for this type of Escort Voith Water Tractors. Each of the two Voith Water Tractors is fitted with two electronically controlled Voith Schneider Propellers size 36R6/255-2.
