After Years in Port,Polar Star Back at Sea

The US Coast Guard Heavy Icebreaker Polar Star(WAGB 10) has finally gone back out to sea following years of engineering upgrades.It joins the Healy(WAGB 20) as the only other heavy icebreaker in the fleet.The Polar Star's sister ship,Polar Sea(WAGB 11),was also upgraded,but suffered an engine failure in 2010 and is slated for decommissioning.
The Polar Star is on a two week shakedown voyage,the Coast Guard said,out of its Seattle homeport.The ship is capable of rocking itself free of ice by means of three pairs of connecting tanks on opposite sides of the ship.Returning it to sea has been a priority in recent years as the Healy was left to do all the Arctic icebreaking on its own.
Polar Star was commissioned in 1976.It is estimated that building a new heavy icebreaker would cost upwards of a billion dollars-no mean feat in these cash-strapped times.
The vessel has five scientific labs and room for 20-35 researchers,in addition to the Coast Guard complement of 134 crew.It is 379 feet long,with a beam of 83.5 feet,and can sail at a speed of 20 knots.
Besides Arctic and Antarctic icebreaking,it supports research in such fields as geology,vulcanology,oceanography and sea-ice physics.
Polar Star carries two helicopters on major deployments.They are used for ice reconnaissance,scientific support,cargo transfer and search and rescue.The ship's armament consists of small arms.
Two blog posts by the Polar Star's crew are posted below to give an idea of the years of engineering work that was done to upgrade the ship.

Shop Talk:Icebreaker and the Environment

Dear Readers,
There's an interesting post below this one.It's about the US Coast Guard Cutter Healy's Arctic Cruise 2012.I think some of you like icebreakers,wlidlife and the environment.You should read the preceding post,then.It's right below this one.I think you'll appreciate it.

USCGC Healy Underway in Arctic-icebreaker is on scientific mission

The US Coast Guard Cutter Healy(WAGB 20),an icebreaker,has been underway for 10 days now.It is on Arctic Cruise 2012,a mission to study ocean acidification.The mission is conducted in cooperation with the Extended Continental Shelf Project.
The Healy spotted a polar bear on Labor Day.It was sitting on ice about a mile from the icebreaker.Polar bears are listed as a threatened species under the Endangered Species Act.Ringed seals are their main food.
Ocean acidification is occurring as melted ice results in more sea water being exposed to the atmosphere and its surplus of greenhouse gas carbon dioxide.The ocean absorbs about one quarter of human-produced carbon dioxide.This may affect the oceanic ecosystem,causing reduced shell formation;habitat loss;and less food for predators.The United States Geological Survey is researching such effects in polar and other regions by conducting field assessments;experimental laboratory studies;and existing data evaluation.
Scientists from the USGS and other institutes are aboard the Healy on the 4-week Arctic Cruise 2012.They are measuring baseline seawater chemistry to better understand ocean acidification in polar regions,collecting seawater and mineral samples and analyzing data.
The Healy is homeported in Seattle,Washington.It has a crew of 75 and can carry 45 scientists.The Healy is armed with small arms.

Canadian Coast Guard To Receive New Icebreaker

Canada has awarded a design contract for a new polar icebreaker to STX Canada Marine.The vessel is slated to replace the current flagship icebreaker Canadian Coast Guard Ship Louis S. St.-Laurent in 2017.The Canadian Coast Guard operates a number of other light to heavy icebreakers.The new ship will be 140 meters long-or 454.3 feet-and displace 23,000 tonnes.It will be capable of breaking ice about 2.4 meters/8 feet thick.This John G. Diefenbaker class ship will carry out a wide range of Arctic and winter missions for Fisheries and Oceans Canada,the Canadian Coast Guard's parent ministry.These will include everything from scientific research to fisheries and sovereignty enforcement and search and rescue.In the meantime,CGCS Louis S. St.-Laurent will continue to carry out such missions.Since 2008,she has been conducting Arctic research annually with U.S. Coast Guard Cutter Healy(WAGB-20),America's only functional polar icebreaker at this time.The Canada-U.S. Joint Expedition program has been an effort to ascertain the delineation of the extended continental shelf in the Arctic.This is important for the protection,management and use of ocean resources under the Convention on the Law of the Sea,which requires a defintion of rights in concrete geographical terms.The research involves gathering bathymetric data for a 3D map of the ocean floor,as well as seismic reflection data for a cross-section view of beneath the ocean floor.Another American polar icebreaker,USCGC Polar Star(WAGB-10),is currently being reactivated for return to service in 2013.This blog would like to extend hearty congratulations to the Canadian Coast Guard on the occasion of its 50th anniversary year.

USCGC Healy Prepares For Summer Patrol

The U.S. Coast Guard Cutter Healy(WAGB-20)is in a standard maintenance period at its Seattle,Washington homeport.The Healy is America's only operational polar icebreaker.The Polar Star(WAGB-10)is being reactivated at Vigor Shipyard in Seattle for service in 2013.
Polar Sea(WAGB-11)had an engine failure and is slated for decommissioning.President Barack Obama included initial funding for a replacement icebreaker in his 2013 budget request.
The Healy is mainly used for scientific research with its five labs.It can accommodate up to 50 scientists,along with 85 crew.Cruising at 12 knots,it has a maximum speed of 17 knots and can continuously break 4.5 feet of ice.The Healy became operational in 2000.
As a Coast Guard Cutter,the Healy can also perform other missions,such as logistics;search and rescue;ship escort;environmental protection;and enforcement of laws and treaties in the Polar Regions.Indeed,this past January the Healy escorted the Russian fuel tanker Renda through the Bering Sea ice to deliver urgently needed fuel to Nome,Alaska.Nome had missed its November fuel delivery because of inclement weather and may not have had enough fuel to get through the winter.
That was an unplanned mission.The Healy was to have headed home for Christmas on 17 December.Instead,it completed the escort mission on 29 January.It had left homeport on 27 May,and arrived back on 5 February.
Captain Beverly A. Havlik is Commanding Officer of USCGC Healy.

Admiral Papp Assumes Command

The Coast Guard has a new Commandant.He is Admiral Robert J. Papp,Jr.Admiral Papp succeeds Admiral Thad W. Allen,who continues to lead the BP oil spill effort in retirement.Admiral Papp graduated from the Coast Guard Academy in 1975,going on to earn a master of arts degree in national security and strategic studies from the Naval War College,as well as a master of science in management from Salve Regina University.The admiral had served as Atlantic Area Commander,Commander of Defense Force East and Chief of Staff Coast Guard.
Admiral Papp is committed to all the Coast Guard's many missions,from search and rescue to drug interdiction and the newer counter-terrorism and anti-piracy missions off Somalia.He is additionally concerned about the need to consider a new ice breaker for the Arctic patrol function,which could cost upwards of a billion dollars to build.The only active icebreaker is the Polar Sea,which will be retired in a few years.There is an effort underway to refurbish the mothballed Polar Star for another seven to eight years of service.With activity in the Arctic picking up in recent years,the icebreaker issue is becoming more critical than ever before.
Now belonging to the Department of Homeland Security,the Coast Guard has 42,000 active duty personnel,in addition to 7,000 civilian workers.It has assisted with maritime security in the Iraq War.
