Netherlands-based marine services company Muller Dordrecht recently added a newbuild vessel to its fleet of harbour and offshore support tugs. Built by the Damen Shipyards Group at its Damen Song Cam Shipyard in Vietnam, the ASD tug En Avant 25 was designed for harbour and offshore towing, terminal support, escort, and firefighting duties.

The tug has an LOA of 32.7 metres, a beam of 12.82 metres, a maximum draught of 6.2 metres, and space for 10 crewmembers. Two Caterpillar 3516C IMO Tier III-compliant main engines that each produce 2,525 kW at 1,800 rpm drive Kongsberg Maritime 3,000mm fixed-pitch propellers to deliver a speed of 13.6 knots and a maximum bollard pull of 85 tonnes. The propulsion setup also includes two Caterpillar C4.4 auxiliary engines and two Leroy Somer 107VA generators.

The tug also boasts 65 square metres of free deck space, making it also suitable for material stowage. The deck equipment consists of a Heila crane, towing and escort winches supplied by Damen Marine Components, and a Mampaey towing hook. For firefighting, the vessel relies on two main engine-driven pumps and two remotely-operated foam/water monitors fitted forward of the wheelhouse. The two monitors have a combined maximum discharge rate of 2,400 cubic metres per hour.

The communications and navigation electronics include a Kongsberg Maritime wheelhouse control station, a Cassens and Plath compass, radars, echosounders and AIS from Furuno, an autopilot and a GPS from Simrad, Jotron EPIRB and SART, a Transas Marine ECDIS, a Gill Instruments anemometer, and Sailor VHF and MF/HF radios. Two Norselight 2,000W searchlights and an Orlaco CCTV camera suite are also fitted.

Space is also available for a Whaly tender that can also be operated as a MOB boat. The crew accommodations meanwhile include one-person cabins for the captain and the chief engineer, four two-man cabins for the remaining personnel, a galley, and a mess.

Other key equipment are a reverse osmosis watermaker that can produce up to four cubic metres of fresh water per day and general service and fuel transfer pumps from Azcue.

En Avant 25 was designed in compliance to Bureau Veritas’ Escort Tug, Unrestricted Service, Fifi1, and Green Passport EU notations.
