This is coolbert:
From Freeper understand fully well that IT IS NOT AMERICAN SUBMARINES ALONE THAT SUFFER FROM SLIPSHOD FAULTY WELDING OF PIPING!
"Wonky welds keep West Coast submarines stuck in port (Canada)"
"More bad news for Canada's problem-plagued submarine fleet: two of the boats will be out of commission for most of this year because of shoddy welding."
"HMCS Chicoutimi and its sister, HMCS Victoria, are stuck in their Vancouver Island port for months because several hundred welds can't be trusted to hold tight when the boats dive. "
. . . .
"Weld problems on HMCS Chicoutimi are costing the navy about eight months' downtime, with the submarine returning to sea only in the autumn. Beginning in February this year, technicians had to inspect 344 suspect welds on the boat and found at least 30 needed re-welding, often in tight spaces where work is difficult."
It can also be surmised that these used boats as purchased from the English Royal Navy were defective to begin with!!
Upholder/Victoria class submarine [Chicoutimi] ON THE FIRST VOYAGE ACROSS THE ATLANTIC UNABLE TO PROCEED ONLY A FEW MILES FROM PORT BEFORE HAVING TO RETURN!!
"HMCS Chicoutimi is a Victoria-class long-range hunter-killer (SSK) submarine of the Royal Canadian Navy, originally built and operated by the Royal Navy as HMS Upholder. Shortly after being handed over by the United Kingdom to Canada she was involved in a partial flooding incident which resulted in a fire at sea. The incident sparked a fierce debate over the value of the purchase of this group of second-hand vessels, as well as the handover inspection process."
HMCS Victoria, the "sister-ship" of the Chicoutimi also encountering problems and having to much excessive "downtime", not on patrol.
"Between 2000 and 2010, Victoria had only been at sea for 115 days; and was expected to re-enter service in mid-2011, after six years in drydock."
