NOAA has awarded JAG Alaska, Inc., based in Seward, a $95.4 million contract to complete major upgrades and maintenance on NOAA Ship Oscar Dyson, a vital research vessel supporting Alaskan and Arctic fisheries.
Scheduled to begin after the 2026 field season, the year-long overhaul will modernize the 20-year-old ship, extending its service life and enhancing operational efficiency.
Upgrades will include a new variable-speed propulsion system, Tier 4 generators, improved fire detection systems, and increased single-occupancy crew quarters. These improvements aim to boost fuel efficiency, safety, and scientific capabilities.
Oscar Dyson plays a critical role in fisheries research in northern waters,” said Rear Adm. Chad Cary of NOAA. “These upgrades will ensure it remains at the forefront of marine science.”
Commissioned in 2005, the vessel is central to monitoring Alaska pollock, one of the world’s largest commercial fisheries.
During its maintenance, NOAA will modify other ships, including the Bell M. Shimada, to maintain data collection in Alaskan waters.
Senators Lisa Murkowski and Dan Sullivan praised the investment for supporting the local economy and preserving essential fisheries research. “This renovation keeps jobs in Alaska and ensures the future of sustainable fisheries,” said Murkowski.
“Homeported in Kodiak, this research vessel plays a vital role in conducting surveys of fish, mammals, and other invertebrates and helps support robust and sustainable fisheries,” said Sen. Dan Sullivan. “Even better, I am glad to see one of our great Alaskan shipyards will be conducting the repairs, keeping the ship close to home so that it can swiftly return to its important work once the maintenance is finished.”
The Oscar Dyson is expected to return to service for the 2028 field season.
