Decommissioned ice breaker passing Astoria, Oregon. They support scientific parties, do ice reconnaissance, cargo transfer, and search and rescue as required. [2] A congressional authorization required the Coast Guard to make a report to Congress on the feasibility of retrofitting Polar Sea. During Antarctic deployments, the primary missions include breaking a channel through the sea ice to resupply the McMurdo Station in the Ross Sea. Polar Sea has been out of service since 2010 due to failure of five of her six Alco main diesel engines. 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. 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]. In nautical history, Polar Sea holds several notable records. this design does not use sharp edges or hammer-like blows to cut or break the ice, as the round bow and massive weight are sufficient. Today, the Coast Guard announced the 399-foot Cutter POLAR SEA suffered an unexpected engine casualty and will be unable to deploy on its scheduled fall 2010 Arctic patrol and may be unavailable for Operation Deep Freeze, Dec. 20 to Jan 2, 2011. The ship is in good shape this year … The proposed new icebreaker is projected to cost about… The vessel Ocean Giant lines up with the US Coast Guard Cutter Polar Star for escort to McMurdo Station, January 25, 2017. [5] Polar Sea has been out of service since 2010 due to engine failure. 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. Coast Guard heavy icebreaker USCGC Polar Star got closer to Santa’s home than most as they set a record for the northernmost wintertime navigation by a … Homeported in Seattle since being commissioned in 1977, POLAR SEA has operated around the globe. 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). Her home port is Seattle, Washington. 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. Publication of the plans enraged the Canadian public opinion as it was regarded as a breach and disregard of sovereignty and prompted the government to take preventive measures in defending Canada's arctic territories. 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. 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). The refit was expected to be completed by September 2008. 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. Homeported in Seattle, Washington, Polar Sea and Polar Star operate under the control of Pacific Area and coordinate their operations through the Ice Operations Section of the United States Coast Guard. 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. An extreme exception to this occurred during a rapid transit to Pt. "[16], A condition assessment of Polar Sea in August 2016 indicated that only one out of six of the 1,200 system components were supportable for five years or more. 4005; 113th Congress), a bill that would amend laws that govern the activities of the United States Coast Guard (USCG), the Maritime Administration (MARAD) within the Department of Transportation, and the Federal Maritime Commission (FMC). [6] The "J"-shaped cranes and work areas near the stern and port side of ship give scientists the capability to do at-sea studies in the fields of geology, vulcanology, oceanography, sea-ice physics and other disciplines. Contrary to some myths,[according to whom?] The extensive use of automation and low maintenance materials have greatly reduced staffing requirements. The cost of repairing Polar Sea would be astronomical to consider, Raj said. Michael Davanzo, The harsh conditions in the polar regions take a toll on the 41-year-old Polar Star. Would make the vessel good for another 25 years. The crew supported the NSF by cutting a resupply channel through 15 miles of Antarctic ice in the Ross Sea and escorting supply vessels to the continent. 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, dates back to the 1970s. Polar Sea has been sidelined since 2010, when an engine casualty left the ship immobilized. Copyright © 2021.

US Coast Guard/Chief Petty Officer David Mosley. On March 25, 2008 the Navy Times described options for the refit or replacement of the older Polar-class vessels. Resupply ships use the channel to bring food, fuel, and other goods to make it through another winter. Polar Sea has a variety of missions while operating in polar regions. Polar Sea has been out of service since 2010 due to failure of five of her six Alco main diesel engines. Her home port is Seattle, Washington. . For years, having only one working heavy icebreaker hindered the Coast Guard’s ability to satisfy mission requests from government agencies effectively. [17] In February 2017, it was stated that Polar Sea would not be refurbished due to high cost; instead, the icebreaker would be used as a "parts donor" for Polar Star.[18]. Three aviation-grade gas turbine engines provide USCGC POLAR STAR with up to 75,000 horsepower, … 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. Would make the vessel good for another seven to ten years. Curt Dawson, a deck engineer for Foss was on the assist tug and offer this description of the trip. Son port d'attache est Seattle et sa zone d'activité est le Pacifique et l'Antarctique. USCGC Polar Sea (WAGB-11) is a United States Coast Guard heavy icebreaker. On 11 February 1981, Polar Sea made history when she became the first ship ever to reach Point Barrow, Alaska in the middle of winter.
