The Sea Tantalus is the first of a series of Vard Group (STX) designed platform supply vessels being built at Cochin Shipyard Ltd. in India. The distinctive hull configuration is being built in countries around the world, and the Indian version is the first of four from Cochin.
At 82.2 by 17-meters the Sea Tantalus has a 7.6-meter depth at the main deck. Built to Det Norske veritas (DNV) standards, including clean notation, the new vessel employs diesel-electric propulsion. Power is provided by four 1,635 HP (12,00 kW) Cummins KTA50-DM1-powered electrical generators. These provide power to a wide range of electrical needs of the vessel as well as the twin 2100 mm azimuthing thrusters each of which has a 1,600 kW in put requirement.
A media release from the Cochin Shipyard, explains that the vessel has been assigned the clean notation by DNV to signify the highest levels of environmental compliance. In addition to other environmental friendly provisions, the new PSV is fitted with a ballast water treatment plant to prevent the transfer of harmful aquatic organisms and pathogens.
Other class notations include COMF for low noise and high comfort in the 28-member crew accommodations, Fire Fighter-1 for fi-fi capabilities, Oilrec for the vessel’s oil recovery potential, and LFL as the vessel can safely carry liquids such as methanol in specialized stainless steel tanks.
With a design speed of 14-knots, the Sea Tantalus has tankage for 1,000 cubic meters of fuel, 1,050 m3 of water and 250 m3 of lube oil. The cargo deck has a 2,100-ton capacity. Engines and engine application support was provided by Cummins Korea. The Sea Tantalus, delivered in March of 2013, will be followed by the Sea Titus, currently on sea trials, in the second quarter, the Sea Tortuga in the third quarter and the Sea Triumph in the fourth quarter of 2013
