The State of Alaska is gathering budgetary and technical input to repower the research vessel R/V Medeia. - Buyer: State of Alaska, Department of Fish and Game, Division of Commercial Fisheries. - Opportunity: A request for information for planning and budget estimates, not a binding bid or award. - Requested equipment: Two main propulsion engines and two matched marine gears, plus propulsion controls, monitoring, starting and electrical equipment, exhaust and cooling components, and a one-year spares package. - Caterpillar (CAT C18/C18 B) is preferred; the conceptual study evaluates two CAT C18 B Heavy Duty engines rated at 636 HP each. - Cummins QSK19-M is acceptable. John Deere and Detroit are also identified as possible engine alternatives. No replacement gear make or model is specified. - Existing equipment: Two Detroit Diesel 16V-92 engines and Twin Disc MG-530 gears are to be removed. Existing propellers, shafts, and installed keel coolers are important compatibility considerations; the existing 4.04:1 gear ratio is a reference, not a requirement. - Work scope: Ship check, engineering and design; removal and installation; system integration; commissioning, dock and sea trials; stability testing and an updated stability book; documentation, crew training, and facility support. - Notable requirements: Recommend equipment suited to extended idle and light-load operation, frequent clutching, and pot hauling; address current emissions requirements and cooling needs; provide lead times, estimated vessel outage, budget prices, qualifications, and identify authorized engine and gear parts-and-service dealers in Juneau. Sea trials include at least four hours at rated load; stability documentation covers up to six operating conditions. - Schedule: The target work window is November 2027 through March 2028, with an approximate 30-day outage target; contractors are asked to confirm realistic timing. - Other named organizations and suppliers: Elliott Bay Design Group prepared the conceptual repower study; Universal Iron Works is identified as the vessel builder.
