En … Polar Sea has been sidelined since 2010, when an engine casualty left the ship immobilized. POLAR SEA was built by Lockheed Shipbuilding and Construction Company in Seattle. The report was submitted in November 2013 and indicated that it is feasible to retrofit and reactivate Polar Sea. Polar Sea has been out of service since 2010 due to failure of five of her six Alco main diesel engines. Il a été mis hors service en 2010 à cause de l'usure excessive de ses moteurs diesel. It has not been determined if a new class will be funded, commercial icebreaker leasing options will be explored, and/or if the ship should be scrapped.[11]. The first one is expected by 2023. USCGC Polar Sea (WAGB-11) is a United States Coast Guard heavy icebreaker. 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. [15] One of the provisions of the bill, according to a summary by the Congressional Research Service, "authorizes the Commandant to decommission the icebreaker Polar Sea if the Secretary does not make a determination regarding whether it is cost-effective to reactivate such icebreaker. With high power to back it up, the 13,000-ton (13,200-metric ton) Polar Sea is able to continuously progress through 6 feet (1.8 m) of new hard ice at 3 knots (6 km/h) and break up to 21 feet when using back-and-ram methods. USCGC POLAR SEA (WAGB 11) Coast Guard Cutter POLAR SEA (WAGB 11) is one of the world's most powerful, conventionally propelled icebreakers. USCGC Polar Sea (WAGB-11) is a United States Coast Guard Heavy Icebreaker. 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. During Antarctic deployments, the primary missions include breaking a channel through the sea ice to resupply the McMurdo Station in the Ross Sea. On March 25, 2008 the Navy Times described options for the refit or replacement of the older Polar-class vessels. The vessel Ocean Giant lines up with the US Coast Guard Cutter Polar Star for escort to McMurdo Station, January 25, 2017. 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 … [10] As of February 25, 2015[update] the laid up ship was still in limbo alongside a pier at the Coast Guard Station on Elliott Bay, Seattle. converted), a gymnasium (in an engineering space), and a small ship's store. 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. Disabled fishing vessel Antarctic Chieftain is towed astern of the Coast Guard Cutter Polar Star through sea ice near Antarctica, Feb. 14, 2015. 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. The curved bow and heavy weight allows Polar Sea to force ice edges to break off downward as cusps. The extensive use of automation and low maintenance materials have greatly reduced staffing requirements. 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. Times Syndication Service. Polar Sea has been out of service since 2010, when it suffered a major engine failure. 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. Homeported in Seattle since being commissioned in 1977, POLAR SEA has operated around the globe. The Polar Star, which was commissioned in 1976, is the Coast Guard's only operational heavy icebreaker, and it can break ice up to 21 feet thick. The four options laid out were: On June 16, 2008 the US Coast Guard announced that Polar Sea would undergo a $6.3 million refit in the Todd Shipyards in Seattle. 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. Coast Guard Commandant Adm. Paul Zukunft has said the Polar Star is "literally on life support," and the service plans to build at least three heavy and three medium icebreakers to fill out the fleet. Details for the ship Uscgc Polar Sea , Other Ship with current real time AIS position and ship photos by vesseltracker.com. 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. Polar Sea has been out of service since 2010 due to complete failure of five of her six … Resupply ships use the channel to bring food, fuel, and other goods to make it through another winter. Barrow, Alaska between January 29 and February 11, 1981. Members of the Coast Guard cutter Polar Star's engineering department make repairs in the ship's motor room while in the Ross Sea near Antarctica, January 16, 2018.

Commissioned in 1976, she was built by Lockheed Shipbuilding along with her now decommissioned sister ship, POLAR SEA (WAGB 11). Today, “Polar Star” remains in proud isolation in the linear icebreaker fleet of the United States, and the “Polar Sea” of the same type has been turned into a spare parts warehouse for its sister ship. $5,515,503 for its maintenance of Polar Sea.[14]. United States Coast Guard Historian's Office. There is a crew of 24 officers, 20 chief petty officers and 102 enlisted.

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. Polar Sea has sufficient hull strength to absorb the high-powered ice ramming common to her operations. It was slated for demolition in 2012, but the scrapping of the 35-year … [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. Her home port is Seattle, Washington. WAGB-11 USCGC Polar Sea, Polar class Icebreakers, US Coast Guard history and characteristics 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. Polar Sea carried two HH-65 Dolphin helicopters during major deployments. In 1985, Polar Sea triggered a diplomatic event by navigating the Northwest Passage from Greenland to Alaska without authorization from the Canadian government. Homeported in Seattle, Washington, US Coast Guard Cutter POLAR STAR (WAGB 10) is the United States' only heavy icebreaker.

Polar Sea has been out of service since 2010 due to failure of five of her six Alco main diesel engines. 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. Polar Sea's hull shape is designed to maximize icebreaking by efficiently combining the forces of the ship's forward motion, the downward pull of gravity on the bow, and the upward push of the inherent buoyancy of the stern. 13-15 feet thick.
