The curved bow and heavy weight allows Polar Sea to force ice edges to break off downward as cusps. Christopher Woody/Google MapsMcMurdo Station, opened in December 1955, is the largest Antarctic station, located on the solid ground farthest south that is accessible by ship. A root cause analysis apparently traced the problem to improper installation of piston rings and/or installation of incorrect (chromed vs. plain) rings. 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. February 15, 2015 Total Views: 2 McMurdo Station, opened in 1955, is one of three stations operated year-round by the National Science Foundation and acts as a staging area for teams headed to the South Pole and other research stations deeper in Antarctic. USCGC Polar Sea (WAGB-11): US Coast Guard Photo - The question of whether the Polar Sea should be reactivated has been kicking around for a while. On February 15, 2011, the Coast Guard via ALCOAST 059/11 announced that Polar Sea would be decommissioned by September 2011; however no final decision on her fate has been made as of December 2016. 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.

The shell plating and associated internal support structure are fabricated from steel with superior low-temperature strength. 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. Would make the vessel good for another 25 years. It was the United States’ position that the Northwest Passage was an international strait open to shipping and it sought only to notify Canada rather than ask for permission. The first one is expected by 2023. The Polar Star's crew traced the problem to a programming error between the engine and the ship's electrical system — which, like much of the ship, … 3 knots (5.6 km/h; 3.5 mph) in 6-foot (1.8 m) ice, 16,000 nautical miles (30,000 km; 18,000 mi) at 18 knots (33 km/h; 21 mph), 28,275 nautical miles (52,365 km; 32,538 mi) at 13 knots (24 km/h; 15 mph), This page was last edited on 23 January 2021, at 17:16.

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 has been out of service since 2010 due to failure of five of her six Alco main diesel engines. Requires the Commandant to submit to Congress: (1) a strategy to meet the Coast Guard's Arctic ice operations needs through September 30, 2050; and (2) unless the Secretary determines that it is cost-effective to reactivate Polar Sea, a bridging strategy for maintaining the Coast Guard's polar icebreaking services until at least September 30, 2024 (currently, a bridging strategy for maintaining operations until at least September 30, 2022, is required only if the Secretary determines that it is not cost-effective to reactivate Polar Sea).
