The world’s first harbour tug equipped with the Mampaey Dynamic Oval Towing (DOT) system is in operation at the Port of Peterhead. The results of the vessel in practice clearly demonstrate the added operational value of the DOT-system. The controllability and flexibility added by the DOT-system makes this vessel unique in the tug market. Other tugs with the Dynamic Oval Towing system are under development.

On the 19th of June 2008 the vessel was named “Ugie Runner” by Mrs. Judith Mackie, the wife of the Convenor of Peterhead Port Authority Board. The vessel has a length of 13 meters and a beam of 5,40 meters and was specially designed for this client by MacDuff Ship Design. With the DOT-system, crane and additional 'A' frame for plough dredging this multi-functional vessel is capable of performing a wide range of harbour duties. Two Scania engines, rated at 350 BHP each, produce a bollard pull of 9,3 ton. With the DOT-system over the bow the vessel can rely on a bollard pull of 5,4 ton astern. To withstand the expected dynamic forces, the DOT-system has a safe working load of 15 tons. Contact Macduff Ship design for more information.
