Caterpillar Marine has confirmed that its MaK 8 M 25 C propulsion engines have been selected by Transnet National Ports Authority to power eight identical 70-tonne bollard-pull harbour tugs on order at a South African shipyard. The tugs will be 31 meters in length with a beam of 12.5 meters and will each be powered by 2x MaK 8 M 25 C engines with a total output of approximately 5332 kilowatts (kW). The MaK engines are scheduled to be delivered between 2015 and 2018.

“Caterpillar is firmly committed to providing powerful, sustainable solutions to the global commercial tug operators and our Cat and MaK engines are ideal for operators looking to enhance the efficiency of their operations," said David Surroca, Caterpillar Marine regional sales manager. "With outstanding engine reliability and efficiency, paired with a serviceable, maintenance-friendly design, the MaK engines will help the tug operators in reducing the operating cost and achieving highest uptime without sacrificing performance."

Commenting on the attributes of the Mak engines, Caterpillar said: "MaK engines offer customers a wide range of technical innovations, including excellent load response capabilities, better fuel consumption as well as long intervals between overhauls. The reduced number of components on the engine and the simplicity of the design enable easier overhauls. A proven performer in the commercial marine industry, MaK engines are the chosen power solutions for vessel owners in need of rugged, reliable power."
