Argentine ASD Tug Launches

by Hans | November 11th, 2015

Built to an Argentine design in an Argentine yard, a new 28.8 by 10-meter azimuthing stern drive tug will soon be at work handling ships in her home country. To be named Brutus, the vessel was designed by Ing. Emilio Noël and built by the Astilleros Unidelta S.A. of Buenos Aires. This shipyard, located on the Rio Lujan, in Tigre near Buenos Aires, is noted for highly successful catamaran ferries and continues their innovation with the new tug.
The vessel’s 4.7 meter depth includes the two Rolls-Royce Azimuthing Thrusters, Type US 205/P20 FP. Each of these aft-mounted thrusters is powered by a 16-cylinder Cummins QSK60M diesel engine generating 2700 HP (2013 kW) at 1900 RPM. The hull form features a double chine that broadens aft to give a fine deadrise to the stern that will allow the tug to operate efficiently in both Ahead and Astern modes.

With a design speed of 12-knots the 5400 HP tug is anticipated to deliver a 65-ton bollard pull. On the fore deck a combination Rolls-Royce Hydraulic Towing and anchor winch has been installed. On the aft deck, is a Mapawey Quick Release Disc-type Towing hook, Type DCX50/65 with a 65-ton releae load. Other aft-deck equipment includes a three-ton capstan.

The tug is also fitted with a diesel driven pump-set powered by a Cummins 6BT5.9-D(M) capable of delivering 200 cubic-meters per hour to two monitors each capable of 100 cu.m. per hour. Two 80 kW gensets are each powered by a Cummins 6B-CP engine.
Accomodation is provided for up to ten crew members. Tankage includes 107.4 cubic-meters of fuel, 15.8 of water and 6.5 of lube oil. The vessel is certified Lloyd’s Register Class Notation 100A1 tug / Remolcador de Tiro de navegación Marítima Nacional, Prefectura Naval Argentina.

The tug Brutus will be take advantage of a flexible design to work both as a harbour and ship assist tug as well as doing coastal towing.
