Power Surge for Italian Tractor Tug
01 Oct 2005
Following the sale of some 280 units for genset applications and the propulsion of coastal tankers and general cargo vessels, the MAN B&W L21/31 engine design has made its debut in a tractor tug application.
MAN B&W Diesel A/S of Denmark has been awarded the contract to supply twin 1,000 rpm units in a propulsion engine package for a 30m Italian tractor tug newbuilding. The tug construction is underway at the Italian shipyard Rosetti Marina SpA at Ravenna for the Livorno based Neri Group. Fratelli Neri SpA owns and operates a large and varied fleet of tugs, supply vessels, floating cranes and barges from locations along the Italian east coast.
The propulsion engines will be delivered from Denmark for installation at the yard next month. The finalised tractor tug is scheduled to be delivered to the owner by the end of this year.
Each nine cylinder L21/31 engine is specified to an MCR rating of 2,025kW and will drive a Schottel controllable pitch rudder propeller unit. The engines will also each power an Advance/Asug gearbox, driving hydraulics and fire fighting pumps via a front end PTO.
