Construction
Then named Mister Darby, the boat's construction was completed and it was delivered to Jackson Marine Corporation on 9 February 1997. Its hull, constructed from ordinary strength steel, has an overall length of 42.9 metres (141 ft), a molded breadth of 6.8 metres (22 ft), and a moulded depth of 6.8 metres (22 ft). The boat has a total of 21 tanks: 12 for fuel oil, 5 for ballast water, 5 for lubricating oil, 7 apiece for fresh- and waste-water, a hydraulic oil tank, a slop tank, and an anchor chain locker. The tug can carry up to 6 cubic meters of fuel, has a gross tonnage of 852 GT and a net tonnage of 205 NT.
The boat's propulsion is powered by two Alco Engine Inc. Model 29 F 18 MS&MR engines with a maximum continuous power rating of 2,312.6 kilowatts (3,101.2 hp) apiece. Each engine has 17 228.6-millimetre (9.00 in) cylinders with a piston stroke of 266.7-millimetre (10.50 in). Each engine powers a single cast steel propeller. Electrical power is generated by two 150-kilowatt (200 hp) auxiliary generators.
In 1998, the tugboat was purchased by Donjon and renamed Atlantic Salvor.
