Well, well, well,

and this from the Globe and Mail:

More than a decade ago, the British navy knew of insulation problems on the main power lines in submarines subsequently bought by Canada. But it didn't upgrade the insulation on all four submarines, only partly documented the repairs and never explicitly told the Canadian navy, The Globe and Mail has learned.

Eventually both navies independently devised more durable and watertight upgrades for one water-prone location, but neither regarded it as important to use the upgraded insulation on connections where the high-voltage lines pass through a bulkhead underneath the captain's cabin.

That location is where arcing caused a catastrophic electrical fire earlier this month aboard HMCS Chicoutimi, leaving the newly refurbished submarine crippled and without power, and an officer dying of smoke inhalation.
