Some very experienced and competent people, including seconded BIW staff and Raytheon people, were very wary of contracting the losing yard (both for the AWD and then for block work) to take over the block work from NQEA when they hit contractual problems. The comments included, "would you trust a company that has everything to gain from your failure to provide critical fabrications in a timely fashion and of sufficient quality". They didn't predict what would happen precisely but they fully expected ASC to be screwed in some way and basically said we told you so when the problems with the keel blocks arose.
It wasn't just the dimensional errors in the early blocks at issue, it was the further, brain numbingly (apparently) incompetent, attempts at rework, after the contractor concerned had lobbied very hard to start them from scratch (at a premium). Instead of fixing the dimensional issues by gouging the welds to remove the shell plating to weld new plating correctly, they cut them with cutting tips damaging the framing beneath and then demanded to be allowed to start from scratch at ASCs expense. They basically more than doubled the cost of the rework and the amount of schedule slip.
Then there was the condition of the blocks when delivered. Directional valves installed back to front, manual actuators for the valves installed in inaccessible orientations, weld spatter inside valves, spatter, slag, blasting aggregate, rags, gloves, welding rods, foods rappers and scraps inside pipe segments in the blocks that had supposedly (and ASC had paid to be) tested and preserved.
Some suggested deliberate sabotage, personally I opted for the "never assume malice when stupidity is a perfectly adequate explanation" that gf used to have as his signature. Then again as more and more happened, including the backgrounding of the then Defmin and his subsequent comments about canoes, moves to install the contractor concerned to run the entire AWD project (ignoring the fact that the contractor caused most of the problems), now the issues with the LHDs that appear to show Navantia in a bad light, I am starting to wonder.
