The tugs, to be designed by the Drydocks World in-house design team, will incorporate a range of power and propulsion equipment from Rolls-Royce, including Bergen medium speed gas engines.
Last year the U.S. Environmental Protection Agency (EPA) approved for sale in the US market the latest state-of-the art ECA Tier 3 compliant Rolls-Royce marine gas engines, which are said to be ideal for tug propulsion. They are designed to improve fuel efficiency, dramatically cut harmful methane emissions and meet strict international environmental standards set to take effect in 2016.
