Damen has recently delivered two ASD 2810-series tugs to ARC Towage in Trinidad and Tobago.
The last of a four-vessel order, the 'Manatee' and 'Atlantic Legacy' departed Damen Shipyards Galati in Romania in mid-November.
Following a bunkering stop in Las Palmas, the vessels will arrive at the port of Chaguaramas, Trinidad, and will start work from January 1 2015.
The four sister ships have been adapted to comply with the latest international LNG handling regulations. They will provide towage, escorting, berthing and unberthing services for LNG carriers under a long-term contract for a leading energy company.
All four tugs have a bollard pull of 60 tonnes and a maximum speed of 12.9 knots.
The vessels are also equipped with "rig savers" on all engines, including remote shut-off valves, remote-closing air intakes, gas detection systems and explosion-proof lighting.
Damen Shipyards is also responsible for commissioning and the handover of the vessels.
