NTSB have released their initial investigation
https://www.ntsb.gov/investigations/Pages/DCA24MM0...
Thank you that, interesting so far. Some years ago I was working on a DP Ship (Dynamic Positioning), on DP the ship is kept in location/position by a number of computers, the ship had three reference systems working, the ship had a run off, and was taken out of service for investigation.https://www.ntsb.gov/investigations/Pages/DCA24MM0...
The computer experts spent over a week checking everything they could, and could not find any reason for the incident, it returned to duty, and didnt have any further incidents.
Just wondering if this inverstigation will not reveal the cause?, apart from gremlins.

We have to get scaffold barriers behind the fanbeam reflectors now after a DSV on DP at a different platform followed the reflectors on someones boilersuit and started following them along the platform.

I find it unbelievable that the crew are still on the ship because the US wont allow them off because they dont have any kind of visa clearance. I can understand why but it feels harsh to keep people on a ship that is disabled.
Provided they have water, food, domestic electricity & a/c then it’s exactly the same if you are in port, at sea, under a bridge.My longest trip was 5 months.
Plenty of nations do more.
I prefer to be on-board in refit for instance than in a hotel.
Just so much less hassle.
Lockdown proved how hard it was for non-mariners to get their heads around this concept of being hemmed in & just keeping busy.

I think there is some frustration as their phones have been taken off them by investigation authorities. They have now been given temporary phones but with no data, and all their logins not available etc.
That’s a bit heavy handed.It's a criminal investigation, which would see all relevant computers and phones put in a cupboard somewhere until someone eventually gets round to looking at them.
However, suspects would not normally be denied access to carry on their everyday life unless remanded in prison, so maybe what we're talking about is a defacto house/boat arrest situation, just without any of the legal protections around it.
If the sailors were Americans then perhaps it would be different.

There an oil rig supply (?) ship stuck in Aberdeen harbour for about 2 years a while ago after the owners went bust.
The (foreign) crew were stuck on that even though it was moored to a jetty
That was a little different, it was detained more than once over unpaid wages, the 2nd time ending in seizure and sale of the vessel; they could have gone home but they lacked money for air fares and believed that staying on board improved the likelihood of being paid.The (foreign) crew were stuck on that even though it was moored to a jetty
Report they'll be moving the shop today, at high tide forecast for 5:24 am.
Divers will first inspect the ship to ensure there are no obstructions after demolition experts last week used explosives to remove parts of the collapsed steel bridge trapping the Dali, which still has its 21-man crew onboard.
Salvagers will then draw out up to 1.25 million gallons (4.7 million liters) of water previously pumped into the Dali to stabilize it as ballast, before releasing its anchors and mooring lines.
Then they'll use tugs

If they don't have visas then why would the US let them off the ship?
