Coast Guard awards Polar Star service life extension contract


The Coast Guard today awarded an indefinite quantity, indefinite delivery contract to Mare Island Dry Dock LLC of Vallejo, California, for the Coast Guard Cutter Polar Star service life extension project (SLEP), as part of the In-Service Vessel Sustainment program. The project will recapitalize a number of major systems and extend the service life of the cutter by approximately four years, helping maintain the Coast Guard’s required heavy icebreaking capability while the service transitions heavy icebreaking operations to the new polar security cutter (PSC). The total potential value of all resulting orders is $119.6 million.

The Polar Star SLEP will address targeted systems such as propulsion, communication and machinery control systems for recapitalization and conduct major maintenance to extend the service life of Polar Star beyond the original design service life. By replacing obsolete, unsupportable or maintenance-intensive equipment, the Coast Guard will mitigate the risk of lost operational days due to unplanned maintenance or system failures. The contracted SLEP work items and recurring maintenance will take place within a five-year, annually phased production schedule running from 2021 through 2025. Each phase will be coordinated so that operational commitments such as Operation Deep Freeze will still be met.

Polar Star is the Coast Guard’s only active heavy icebreaker. The 399-foot cutter, commissioned in 1976, supports nine of the 11 Coast Guard statutory missions. The first PSC, currently under design, is on contract for delivery in 2024.
