What is wrong with the welds?? Supposedly, these are x rayed and visually inspected. Was their something wrong with the welding gasses? Perhaps.
Round up the usual subjects.

People responsible for the welding program need to go to jail for a long time.
Preferably, for life.

What is a “Dutch Breech?”

The Canadians bought a bunch of used subs from the Brits that turned out to be lemons.

"...What is a Dutch Breech?.."Looks like an escape hatch.

Bad welds. Not words one wants to hear regarding a sub.

Cargo hatch, I think.

X-ray cameras have been used for welding quality control since the late 1940’s. So why is this a problem now?
Maybe it is about inefficient use of inert gases in the welding process, which means oxidation & weakening of welded joints.

Not to worry, we have a wonky Emperor who should stay in the White House for the next 8 months and 2 1/2 days.

What is a Dutch Breech? It's a section of the hull designed to be easily cut away to allow access to the machinery spaces. You see them on conventional submarines only. The shipyard will open the hull there to remove the diesels or what have you. Then it'll be welded shut again once the work is complete.

Welding processes require constant discipline and support from top management to be successful. Areas such as training and requalification of the welders and nondestructive test personnel require expensive, highly trained individuals to succeed.
Companies with cost cutting, bean counter lead management (MBAs) cut highly compensated individuals in these areas and anyone that stands in their way.
Weld discipline and skills degrade, defective welds are produced and there is no one in the process to detect and correct.
Without proper oversight such as the US SUPSHIPS agency, the defective welds can take years to detect.

I suspect it is porosity as well as cold lapse. X-ray would have picked this up upon inspection unless the inspectors were incompetent or paid to look the other way.
A nuke plant here in Texas had substituted inspection x-rays inserted into files and they got caught after the fact with post build inspections prior to start up. Cost rate payers ALOT of money to fix.

The Dutch Breech is the opening in the hull that enables the loading and unloading of large pieces of equipment that wouldn’t fit down the normal hatch. It’s used primarily only when the boat is in shipyards.

The first was the Dutch Breach, an idea that originated in the Netherlands. It is a large bolted hull section, an area approximately four m2 above the engine room, which allows the removal of diesel-generator sets for maintenance and overhaul. When Canada wanted to change the engines of an Oberon-class submarine, the only solution was to cut the sub in half and then weld it back together.

I’m guessing there is a similar provision for refueling a nuclear sub.

Post #12 says it best, IMO. Quality control is paramount.

Yeah. There are few things more dangerous to a company’s long term health than a Hahvaad MBA.

Way back when, Electric Boat had a welding problem until the welders had to ride the boat on it’s first test dive.

Dutch Breach: At the top of the hull immediately above the diesel generator sets is a Dutch Breach machinery shipping hatch.
I would posit that it is a access for the engines and other equipment.
