Fire Breaks Out on Polar Star

talk about a floating blazing dumpster of a ship! you literally could not make this stuff up!

The 150-member crew of the U.S. Coast Guard Cutter Polar Star fought a fire on February 10 that broke out in the ship’s incinerator room about 650 miles north of McMurdo Sound, Antarctica.

After initial response efforts using four fire extinguishers failed, fire crews spent almost two hours extinguishing the fire. Fire damage was contained inside the incinerator housing. Firefighting water used to cool exhaust pipe in the surrounding area damaged several electrical systems and insulation in the room.

No injuries were reported, and the cause of the fire is under investigation.

Repairs are already being planned for the Polar Star ’s upcoming maintenance period. The incinerator will need to be full functional before next year’s mission.

Commissioned in 1976, the 43-year old ship is operating beyond its expected 30-year service life. The Polar Star crew recently completed Operation Deep Freeze, an annual joint military service mission in support of the National Science Foundation. The Polar Star crew departed their homeport of Seattle on November 27 and traveled more than 11,200 miles to Antarctica.

Upon arrival, the Polar Star broke nearly 17 miles of ice, six to 10 feet thick, in order to open a channel through McMurdo Sound. On January 30, the Polar Star escorted the container ship Ocean Giant through the channel, enabling a 10-day offload of nearly 500 containers with 10 million pounds of goods that will resupply McMurdo Station, Amundsen-Scott South Pole Station and other U.S. field camps.

The February 10 fire was not the first engineering casualty faced by the Polar Star crew this deployment. While en route to Antarctica, one of the ship’s electrical systems began to smoke, causing damage to wiring in an electrical switchboard, and one of the ship’s two evaporators used to make drinkable water failed. The electrical switchboard was repaired by the crew, and the ship’s evaporator was repaired after parts were received during a port call in Wellington, New Zealand.

The ship also experienced a leak from the shaft that drives the ship’s propeller, which halted icebreaking operations to send scuba divers into the water to repair the seal around the shaft. A hyperbaric chamber on loan from the U.S. Navy on board the ship allows Coast Guard divers to make external emergency repairs and inspections of the ship’s hull at sea.

The Polar Star also experienced ship-wide power outages while breaking ice. Crew members spent nine hours shutting down the ship’s power plant and rebooting the electrical system in order to remedy the outages.

Presently, the U.S. Coast Guard maintains two icebreakers – the Coast Guard Cutter Healy , which is a medium icebreaker, and the Polar Star , the United States’ only heavy icebreaker. If a catastrophic event, such as getting stuck in the ice, were to happen to the Healy in the Arctic or to the Polar Star near Antarctica, the U.S. Coast Guard is left without a self-rescue capability.

By contrast, Russia currently operates more than 40 icebreakers.

Reserved for Operation Deep Freeze each year, the Polar Star spends the Southern Hemisphere summer breaking ice near Antarctica, and when the mission is complete, the Polar Star returns annually to dry dock in order to complete critical maintenance and repairs in preparation for the next Operation Deep Freeze mission. Once out of dry dock, the ship returns to Antarctica, and the cycle repeats.

The Coast Guard has been the sole provider of the nation’s polar icebreaking capability since 1965, and is seeking to increase its icebreaking fleet with six new polar security cutters in order to ensure continued national presence and access to the polar regions.

“While we focus our efforts on creating a peaceful and collaborative environment in the Arctic, we’re also responding to the impacts of increased competition in this strategically important region,” said Adm. Karl Schultz, commandant of the U.S. Coast Guard. “Our continued presence will enable us to reinforce positive opportunities and mitigate negative consequences today and tomorrow.”

After leaving Antarctica, the Polar Star crew arrived in New Zealand for a port call, and they are presently en route to their homeport of Seattle.

I’ve seen this blurb a couple times. Maybe they have to have a chamber on board to put divers in the water? USCG regs or something?

Must be a very deep draft vessel.

By specs the divers on the Polar Star can go to 190 feet and the ship can support a chamber, perhaps that’s where that blub comes from. N/A I assume for the work mentioned.

Agree. I think the author made an unwarranted assumption when saying that the chamber permitted diving hull repairs.

Pretty typical now-a-days of poorly informed reporters and writers, and the lack of editorrs.

What’s more appaling is the embarrasing condition of Coast Guard operated ice breakers. It’s shameful and dangerous.

I hope it’s not going to take the loss of crewmen on board to get the federal government to wake up. And not to be overly cynical, but if this were a privately owned, US flagged vessel, there would be hell to pay.

It’s those damned effing kids throwing full aerosol cans of brake cleaner in there…what did they expect would happen? They’re lucky they all didn’t get an eye put out!


Maybe they have a chamber as well as the means to construct a habitat. Not that the two are related, but if they built a habitat to make the repairs underwater it would fit.

And stop running with those scissors!

It’s not a “habitat” it’s a "mobdock. " A form of caisson or cofferdam. Ships have been repaired in-water using those things for a century, the early ones were made of wood.
