Svitzer Brazil
by Marine Log
Brazil’s Estaleiro Rio Maguari (ERM) shipyard has delivered its first ASD (azimuthing stern drive) tug, the Svitzer Arthur. Designed by Robert Allan Ltd., it is the first of a series of six tugs of the same RAmparts 2300-ERM design currently under construction at the shipyard for Svitzer Brazil.
The RAmparts 2300-ERM ASD design is optimized for maximum efficiency in ship-handling operations in harbors. With an overall length of 23.2 meters, the tug features a raised forecastle deck for safer operations in heavier weather.

The ASD tugs in the series are designed and constructed to the following ABS Notation: A1, Towing Vessel, AMS, ABCU, Unrestricted Navigation, UWILD, PMPCBM for Thrusters Only.
Propulsion machinery consists of two MTU

16V4000M63 main diesels and two Kongsberg US205S FP, 2,800 mm diameter Z-drives. Ship-handling fenders at the stern consist of a row of W-fenders. Sheer fendering consists of “D” rubber and “W” block type fendering at the bow.
The accommodations for a crew of six have been outfitted to a high standard for crew comfort. The deckhouse contains an entrance lobby with a public WC, galley, mess, and one officer cabin with ensuite WC. The lower deck contains two double cabins with ensuite WC, and an additional officer cabin with ensuite WC.
The wheelhouse is designed with a single split forward control station which provides maximum all-round visibility with exceptional visibility to the bow and side fendering, and operations on the forward deck.
Trial results were as follows:
• Bollard pull, ahead = 71 tonnes
• Bollard pull, astern = 69 tonnes
• Free running speed, ahead = 13 knots
Svitzer has been operating in Brazil since 2015 and now has a presence across eight ports in the country, the most recently added being the Port of Salvador, including Aratu Port Complexes.
The six ASD tug newbuild program at Estaleiro Rio Maguari is part of Svitzer’s general expansion in Brazil and to support the company’s continued organic growth.
