With the July delivery of the tug Northwind, the Rotterdam-based firm Avra Towage is now operating a fleet of six tugs with a seventh under construction. Three of the company’s original five-boat fleet have Cummins main engines, so it was an easy choice to go with Cummins engines for the Northwind. However, where the others have 2,400 hp and 32 tons of bollard pull with a pair of 38-litre Cummins main engines (tugs South, West, and East), the new boats are powered by a pair of the larger 50-liter Cummins KTA50-M engines.
