GREAT SHIPS of 2017DSV is a marvel of modern techn & designOceanicasub VThe DSV Oceanicasub V was delivered in February 2017 to her Brazilian owner Oceânica. Oceânica provides subsea services to the petroleum company Petrobras. The Oceanicasub V is the second in a pair delivered from the Arpoador Shipyard in Guarujá, Brazil, and the 43 by 9.3-m vessel was designed by Incat Crowther in cooperation with the shipyard and owner. Builders believe that allying shallow diving to a wide range ROV performance, all contained in a light DP 2 vessel, will establish a new benchmark in subsea operations, reducing costs, increasing work ? exibility and safety compared with the previous existing concepts. For such a vessel, choice of engine power and propulsion method is of paramount importance, and the owners chose four Cummins QSK19M main engines and coupled them to ZF 2000 gearboxes driving Hamilton HM521 water jets. With each of the four engines delivering 660 HP, the vessel, at just under 500 gt, has a maximum speed of 12,5 knots and a cruising speed of 10 knots. The jets eliminated the danger that propellers can present for divers. However the primary function of the four jets, along with three 150 kW Intermarine bow thrusters, is to pro-vide precise and safe station keeping when divers are working below. The vessel is also ? tted with a Kongsberg DP2, Hipap, Spot Track and Radius systems to automatically hold position as well. Zero speed stabilizer ? ns are also installed to reduce roll and make the working deck safer for crews. Electrical power for the bow thrusters and a variety of deck cranes and winches is provided by three Cummins QSM11-powered 300 ekW gensets as well as a Cummins 6BT5.9-powered 92 ekW emergency genset. The vessel is also equipped with a hyperbaric chamber, Caviblaster, dive bell, one ROV for 1,500m and one for 300m, ROV A-frame and every conceivable piece of equipment required to handle a wide range of subsea tasks.

She is one of six Independence-variant littoral combat ships currently serving in the U.S. Navy surface com-batant ? eet. These ships are smaller than a typical combatant, but also com-parably less expensive and their large ? ight deck and vast mission bay space allows for ? exibility in how the ship is purposed. Their unique shallow-draft, trimaran hullform is designed to operate in the shallower littoral water (closer to shore) but also to provide a more stable Ship Name USS Omahaplatform in the deeper blue water as Ship Type Independence-variant LCSwell.
