MAN B&W Diesels for Tractor Tug
MAN B&W Diesel A/S, Denmark, has been awarded the contract to supply a twin L21/31 propulsion engine package for a 30 m Italian tractor tug newbuild. Each nine-cylinder L21/31 engine is specified to an MCR rating of 2025 kW, and will drive a Schottel controllable pitch (SRP) rudder propeller unit. Additionally, the engines will each power an Advance/Asug gearbox, driving hydraulics and firefighting pumps, via a front-end PTO. This will be the first application of the 1000 r/min L21/31 engine in a tractor tug, according to the company.
The tug construction has started at the Italian shipyard Rosetti Marino SpA, Ravenna, for the Livorno-based Neri Group. Fratelli Neri SpA, owns and operates a large fleet of various tugs, supply vessels, floating cranes and barges, from various locations along the Italian east coast. The propulsion engines will be delivered from Denmark for installation at the yard during the month of August. The finalized tractor tug is scheduled to be delivered to the owner around the end of the year.
