MarineLink is reporting Argentina has recently completed repairs on their only icebreaker, ARA Almirante Irizar.
There are some remarkable parallels between USCGC Polar Sea and Argentina’s Icebreaker, ARA Almirante Irizar. They are essentially the same size (length and beam within a foot and the same draft) and the same age (both commissioned in the late ’70s). The Polar class ships have much greater horsepower with their gas-turbine engines, but their diesel horsepower is very similar. Both have been out of service for years. The Polar Sea since 2010 after failure of five of her six diesel engines. The Almirante Irizar since 2007 after a serious fire.
Sounds like the required repairs were quite extensive. Not surprisingly it cost more that initially expected and repairs included enhancements rather than just a restoration of the previous configuration.
As the Coast Guard looks at the Polar Sea, we will also likely want to incorporate some changes.
