United States Coast Guard Historian's Office. The Coast Guard's only heavy icebreaker has been fighting engine failure and flooding in the frigid Antarctic, "Although we had less ice this year than last year, we had several engineering challenges to overcome to get to the point where we could position ourselves to moor in McMurdo," Polar Star commanding officer Capt. $5,515,503 for its maintenance of Polar Sea.[14]. On March 25, 2008 the Navy Times described options for the refit or replacement of the older Polar-class vessels. The shell plating and associated internal support structure are fabricated from steel with superior low-temperature strength. The Coast Guard also operates the medium polar icebreaker USCGC Healy, commissioned in 1999, which serves in the Arctic primarily on research projects, although capable of performing a wide variety of other Coast Guard missions. The first one is expected by 2023. Commissioned on 23 February 1978, the ship was built by Lockheed Shipbuilding and Construction Company of Seattle along with her sister ship, Polar Star (WAGB-10). [13] Vice Commandant Adm. Charles Michel says the only choices for continuing the icebreaker missions are either restoring Polar Star while in service or reactivating Polar Sea, at a to be determined cost; this estimate is due in early 2017, so at that time lawmakers will likely decide the ship's fate. Polar Sea has a variety of missions while operating in polar regions. The crew of the Polar Star overcame flooding and engine failure to accomplish their mission supporting Operation Deep Freeze. Later, on January 16, the Coast Guard says the Polar Star’s shaft seal failed, causing flooding in the cutter’s engine room at a rate of approximately 20-gallons per minute. Copyright © 2021.

USCGC Polar Sea (WAGB-11) is a United States Coast Guard heavy icebreaker. For all three shafts, the diesel-electric plants can produce a total of 18,000 shaft horsepower (13,425 kilowatts) and the gas turbine plants a total of 75,000 demand shaft horsepower (56 MW) or 60,000 continuous horsepower (44.8 MW).[5]. Polar Sea uses four different methods[further explanation needed][example needed] of electronic navigation to overcome the difficulties of high-latitude operations, and a computerized propulsion control system to effectively manage six diesel-powered propulsion generators, three diesel-powered ship's service generators, three propulsion gas turbines, and other equipment vital to the operation of the ship. In addition to these duties, Polar Sea also serves as a scientific research platform with five laboratories, additional space for seven portable laboratories on deck and accommodations for up to 35 scientists. It also has its own U.S. Post Office, satellite pay telephones, amateur radio equipment, photo lab, and movie library. Polar Star uses four different methods of electronic navigation to overcome the difficulties of high-latitude operations, and a computerized propulsion control system to effectively manage six diesel-powered propulsion generators, three diesel-powered ship's service generators, three propulsion gas turbines, and other equipment vital to the smooth operation of the ship. Duty on an icebreaker is long and strenuous, especially when it involves being away from homeport for up to eight months out of the year. Polar Sea has been sidelined since 2010, when an engine casualty left the ship immobilized. On January 11, there was a failure in one of the ship's three main gas turbines, which produce the power needed for the ship's propellers to break up thick, multiyear accumulations of ice.
