Great Lakes Dredge & Dock Corp. announced in October the delivery of two 99'×41'×12'dredge support vessels from Conrad Shipyard, Morgan City, La. The Cape Hatteras and the Cape Canaveral are Damen 3013 multicats. Main propulsion comes from three Caterpillar 3412D TTA diesel engines, producing a total of 2,500 hp at 1,800 rpm. The mains will connect to Promarin fixed-pitch wheels in Optima nozzles through Reintjes WAF 464 marine gears with 5.591:1 ratios. The propulsion package will give the new multicats a speed of 9.6 knots and a bollard pull of 35 metric tons. For added maneuverability, the new multi-purpose dredge support vessels will feature a 360° hydraulically driven, 310-hp bowthruster (no manufacturer given). |
