New ASD Tug: Brazil Designed & Built
By Alan Haig-Brown
The Brazilian Port of Recife/Pernambuco is served by a powerful new ship-handling tug. The owners, Navemar Transportes e Comércio Marítimo, took delivery of the vessel, named Navemar XIII, this past September 2010.
The 98.4-ft azimuthing stern drive tug carries a 32.1-ft beam with a depth of 15.2 ft. The Z-drives are a pair of HRP-Series 7000, each drive is powered by a 2200 HP (1641 kW) at 1800-RPM Cummins QSK60 engines. The tug, which is fitted with a bow-mounted hawser winch and a deck-mounted towing winch, has a 55-ton bollard pull.
Designed and built by Brazil's Corema Indústria e Comércio Ltda, the tug features a double chine hull that allows for good lateral movement and a raked stern profile for good backing, both of which make for improved ship handling. Electrical power is provided by a Scania-powered generator. Tankage is provided for 18000 liters of fuel and accommodation is provided for up to eight crew members.
