Norris Warming Balder Challenger has an overall length of about 236 feet, molded beam of 52.5 feet, depth to main deck of 23.8 feet, and design draft of 18.9 feet. Her main propulsion plant comprises two MLW (Bombardier) diesel engines, each with an output of 2,712 bhp at 1,100 rpm, providing a service speed of 14 knots. Electrical power is provided by two 1,360-kva alternators driven by power takeoffs on the gearboxes via flexible couplings. Also installed are three diesel-driven alternator sets for ship's service duties, each rated at 490 kva, and a 12-kw emergency diesel generator set. For diving support applications, the vessel is fitted with a fully redundant dynamic positioning sys- tem that meets the Lloyd's Register A-A classification. Three indepen- dent reference systems are pro- vided: a vertical taut wire system, an Artemis microwave system, and a hydro-acoustic positioning system, the latter a dual system with full transducer/transponder back-up. All sensitive equipment is located in an independently air-conditioned computer room. To aid maneuver- ability and offer full redundancy, the vessel is fitted with two 800-hp bow thrusters and two 600-hp stern thrusters. A moonpool is installed amidships, fully serviced with com- pressed air, fuel, and electric power outlets. During the initial design stage, emphasis was given to an optimum hull shape producing good seakeep- ing qualities in marginal weather conditions, and best utilization of space for liquid and dry bulk car- goes. For offshore supply work, the vessel has the following capacities: 800 tons of drill/ballast water, 1,000 BALDER CHALLENGER Marystown The first of its new M9700 diving support/supply vessel design, the Balder Challenger, has been deliv- ered by Marystown Shipyard Lim- ited of Marystown, Newfoundland, to Labrador Offshore Shipping Company Limited.
