NOAA’s Alaska Fisheries Science Center is conducting market research via a Sources Sought notice—not a solicitation—for a charter vessel to conduct a longline survey for sablefish and other groundfish in the Eastern Bering Sea, Aleutian Islands region, and Gulf of Alaska. The updated 2027–2031 draft SOW envisions the contractor cleaning, processing, and freezing commercially marketable catch not retained for biological sampling, selling it within three months of the final fishing day, and crediting sales revenue against total charter reimbursement costs. Contractors would invoice for sea days and fuel after Government review and approval of a mandatory Post-Survey Sales Report; after the first cruise leg, actual fuel use, catch data, and cost-recovery projections are provided, and the Government may adjust remaining survey days if revenues or agency funding fluctuate. Interested firms are asked to provide a capabilities statement covering company size, vessel specifications, ability to meet draft SOW requirements, UEI, SBA status, recent relevant experience, comments on the cost-recovery offset model and alternative survey arrangements, and a ROM estimate with key cost drivers. The notice seeks industry input on vendor capability, interest, availability, compensation structures, and alternatives to reduce cost and operational risk, with the draft SOW subject to change and no Government commitment.
