Robert Allan Designed Tugboat Delivered to Colombia
The new tugboat, Media Luna, sailed into Puerto de Bolivar, Colombia to be welcomed by other Cerrejón towing vessels providing fire monitor displays. Media Luna was constructed at Uzmar Tug and Work Boat Factory in Izmit, Turkey.
This is the first of a two boat order for the AVT 3000 Class Tugs designed by Robert Allan Ltd., Naval Architects of Vancouver, B.C., Canada. The Media Luna will replace the Riohacha as part of a Cerrejón’s fleet renewal program. The sister vessel Cabo del Vela is expected to be delivered to Cerrejón’s Puerto Bolivar marine operations in March of this year.
The AVT 3000 was designed to meet Cerrejón’s requirements for performance, propulsion equipment, accommodations, tank capacities and outfit. She features a partial raised focsle for operation in rough weather and a large functional aft working deck for efficient ship handling operations. Designed for a bollard pull of 60 tonnes, she will be the most powerful tug in the Puerto Bolivar fleet.
Particulars of the Media Luna are as follows:
- Length overall: 30.75 m
- Beam, moulded: 12.0 m
- Depth, moulded: 4.80 m
- Maximum draft (overall): 6.2 m
The tug was designed and constructed to BV Class requirements with the notation: BV 1, HULL, MACH, TUG, Unrestricted Service'
Main propulsion consists of a pair of General Electric 12V228 diesel engines, each rated 2289 kW at 1050 rpm, and each driving aVoith Schneider 30R5-250 cycloidal propeller.
The electrical plant comprises 2 identical Caterpillar C 6.6 ACERT diesel gensets, each with a power output of 125 ekW, 60 Hz, 480V.
The aft deck machinery includes a Rolls Royce ATWH 1500/200 render-recover hawser/towing winch with horizontal warping head. The winch has a pull of 20 tonnes at 18m/min. and 5 tonnes at 50m/min. Rendering capability is 30 tonnes at 30m/min and 8 tonnes at 80m/min. Also on the aft deck is a Hella deck crane rated 5 tonnes at 5m reach.
On the foredeck is a Rolls Royce AW20.5U2H anchor windlass with two cable lifters and two horizontal warping heads.
On trials, Media Luna met or exceeded all performance expectations, with a bollard pull, ahead of 63.1 tonnes and a ree running speed of 13.6 knots.
