“Coast Guard Cutter Healy experiences engineering casualty” –Coast Guard News

 

The Coast Guard Cutter Healy (WAGB 20) returns to Seattle following a two-month Arctic patrol, Aug. 16, 2024. The Healy is the United States’ largest Polar icebreaker and was commissioned in 2000. (U.S. Coast Guard photo by Petty Officer 2nd Class Taylor Tracy)

Coast Guard News reports,

“WASHINGTON – U.S. Coast Guard Cutter (CGC) Healy experienced a significant engineering casualty while operating northwest of Port Angeles, Washington. There were no reported injuries. On July 13th, tugs safely towed CGC Healy back to homeport for an investigation into the incident and to undergo major repairs.”

Sounds like they already know this was a major casualty.

  1. I try to keep the blog apolitical, so we stay on topic.

    I was taught the military was supposed to be apolitical.

    The news release talks about Trump’s vision as if more ice breakers was exclusively his idea when we have been saying we need more Icebreakers for at least a decade and the ICE Pact was completed during the previous administration.

  2. The USCGC Healy (WAGB-20) utilizes an AC/AC cycloconverter diesel-electric propulsion system delivering up to 30,000 maximum shaft horsepower.

    Power Generation and Drive System

    • Generating Plant: Four medium-speed Wärtsilä-Sulzer 12ZAV40S diesel generators housed in two separate, fire-divided engine rooms, producing a combined 10,620 brake horsepower per unit.
    • Drive Motors: Two 11.2 MW AC synchronous main propulsion electric motors powering the twin shafts.
    • Electrical Architecture: AC/AC cycloconverters adjust frequency and voltage smoothly to control motor speed and torque precisely during heavy icebreaking operations.

    Propellers and Performance

    • Propellers: Two 4-bladed, fixed-pitch propellers operating at 160 RPM for a top speed of 17 knots.
    • Icebreaking Capacity: Continuously breaks 4.5 feet of ice at 3 knots, or up to 8 feet using a backing-and-ramming technique.
    • Auxiliary Thrust: Includes a 2,200-horsepower Omnithruster bow thruster integrated into a dynamic positioning system for precise station-keeping during scientific deployments.

    Two engine rooms with independent shafts and screws. HUMM?!

  3. Nice edits, I was also appalled at much of the release

    However it is disturbing the lack of information, and a ship that is designed to reduce single point failures to need to be towed home is not a good sign.

    The crews on these ships are pretty sharp and have access to shore-side engineering resources, this does not sound good to me.

    • In a world where the Chinese are literally waiting to pounce, we SHOULD NOT BE telling the world what’s going on with our ships. If this were the good days of the ‘peace dividend’ era, I’d agree that more information is required. Right now, we should basically be considering ourselves at war. The Chinese already are.

      • There’s ‘hey, we had a problem’, and there’s ‘it caught fire, and we barely stopped it from burning to the water line’. “Hey, we had a problem,” is potentially fixable at short notice. “Caught fire and we barely stopped it from burning to the water line.” is another story. That case means drydocking and cutting a hole in the side of the boat. Ie days to weeks of repair vs months to years of repairs.

        There is value in not letting a foe know just how badly damaged a ship is, even if they can literally see it being towed.

      • Soon we will be advertising for a shipyard to do the repairs. That will include scope of work. We currently don’t know what that is, but the fact that they were not able to make way on even one shaft makes it pretty clear the casualty is severe.

        Now if we had a Coast Guard Yard on the West Coast we might be able to keep the scope of work private but I don’t really think we gain or loose anything.

        If China wants to know when the ship is in the yard and when they come out, they will know. Really I doubt if they are that interested, since it will not change anything they do.
