Can we please focus on the elephant in the room.
Where's the video of the "incident" that caused the grounding ?
I kinda doubt that will be released. If it was rigger in question who okay-ed the wrong closing loop, they probably wouldn't want a video record of a mistake in the public domain...the manufacturer probably doesn't want a video out showing the rig isn't idiot proof.
I'm with Paul and John on this one. There is anecdotal evidence that some modern rigs aren't getting timely reserve deployments. From a statistical point of view, 15 test pulls is nothing and doesn't account for a number of variables.
A few examples. Sweden is a cold European country - what temperature was the rig at on the failed pull? Second question - a routine repack is after the rig has 'settled' for about 6 months (I don't know the Swedish repack cycle). There is a heck of a lot that may have caused the issue.
If the pack is so critical that a closing loop less than an inch too long causes a total mal, doesn't seem to be a robust design. I'd hope there is more margin and tolerance available on getting a reserve to launch.
The weirdest things can cause un-expected failures, and from an engineering point of view, I'd say you only understand the failure when you can recreate it.
