What a mistakuh I makuh., That was a pretty stupid question…

Those clocks aren’t very accurate; at least the ones Canon uses. But I doubt if would be off more than an hour or two, barring the change to or from summer time.

There’s growing body of data from all sides – from relatives, from crews working in BOURBON, from those who worked in BOURBON earlier, all coinciding and cross-confirming, all leading to worrisome conclusions – dry dock repairs weren’t complete and of sufficient quality; much more works should be done on propulsion/steering system to ensure safe transatlantic run; the ship wasn’t ready for transatlantic run and shouldn’t be allowed to leave port of departure/repairs (Las Palmas), by relevant authorities. Probably, tug couldn’t avoid disaster by moving away from cyclone track, either, because she didn’t have enough fuel for any extra maneuvering, especially long-distance one.
Regarding the bold text, I suppose that I had run for safety, ship and crew first and worry about the fuel situation later.
There’s more in this cumulative article, with her distress messages: http://maritimebulletin.net/2019/09/27/bourbon-offshore-tug-distressed-in-atlantic-14-crew-waiting-rescue/

This is the end of the story. Water in the engine room and increasing. Impossible to launch life rafts, swell 10 m or more. At 09.57 no more engine power, all down. Message sent at 12.41 is not received by ship, failure delivery report received…
This is starting to make my stomach turn like the el faro transcript did.

Dayuummmm 10 meters in a tug boat with no power…Lucky anybody made it.
Hopefully the survivors will shed some light on what happened soon.
To me, she looks like she was carefully prepared, all rusty spots largely cleaned… ready to get painted.

Yes, you are right. It’s the only explanation for all these spots on the hull unless a swarm of sea gulls passed over the ship…

Regrettably, I suppose we are now moving into the blame game - and who is in charge of investigating?
Nothing seen on on the websites of BEA-Mer, USCG, or Lux CAM thus far.
The distance between the positions at 08.20 UTC and 08.58 UTC is 1.35 nM. The course in which the ship was drifting is then 229° SW and the average speed 2.13 knots.
With that course the wind was blowing from the NE and that indicates that the ship was in the dangerous right forward quadrant of Lorenzo, without engine and emergency power and sinking. They had no chance at all, a real tragedy.
EDIT: this is the wrong link:
These are the specs: Double azimuth stern drive tug NEMED
This is the correct one: Bourbon Rhode
That kind of E/R flooding something big must have opened up Not familiar with Azimuth propeller systems, don’t know how likely something there might have opened up.
The specs show 17 tons/ day fuel consumption at 13 kts, 10 tons/day at 10 kts but only 130 cubic meters of capacity. I wonder what kind of margin they were working with.
If my math is correct:
Total distance is 2738 nmi at 240 mi/day is 11. 4 days or 114 tons of fuel. 130 cubic meters of diesel is about 110 tons.
This contradicts a report from Bourbon quoted in an earlier post: The French offshore vessels owner said water is entering the stern of the 49.5 meter tug supply vessel Bourbon Rhode, about 60 nautical miles south-southeast from the eye of hurricane Lorenzo.
If that report was accurate, with the eye moving NNW and the tug 60 miles to the SSE of it, the wind would have driven them in a NE direction.
The only thing I can say is that I did the calculations with the data, time and position, as sent by the Bourbon Rhode via Inmarsat C.
These GPS positions are usually accurate to 10 m or less while the exact location of the center of the hurricane isn’t exactly known, it is no more then an estimate. The positions show that they were drifting in a SW direction.
HURRICANE LORENZO FORECAST/ADVISORY NUMBER 14
NWS NATIONAL HURRICANE CENTER MIAMI FL AL132019
0900 UTC THU SEP 26 2019THERE ARE NO COASTAL WATCHES OR WARNINGS IN EFFECT.
HURRICANE CENTER LOCATED NEAR 15.1N 39.3W AT 26/0900Z
POSITION ACCURATE WITHIN 25 NM
From the distress message the tug was 15:44.48 N / 039:55.04 at 9:48 UTC
That would put the tug north and west of the eye. The NHC warning gives the error for the eye at 25 NM.
That is the first position and the second one I used for my calculation is 15° 43.6 N 39° 56.1 W at 09.58 UTC.
I believe you. It exceeds all the margins of errors so it’s most likely an incorrect report or a bad translation of one from the company. I was questioning the report, not your calculations.

The distance between those two positions is 52 miles.
Here is the wind field at the time by NHC:
ESTIMATED MINIMUM CENTRAL PRESSURE 974 MB
MAX SUSTAINED WINDS 85 KT WITH GUSTS TO 105 KT.
64 KT… 30NE 10SE 10SW 30NW.
50 KT… 90NE 40SE 20SW 80NW
34 KT…180NE 90SE 80SW 170NW.
Given a 25 mile error in position of the system looks like the tug would have to have been inside the 50 kt wind field but outside hurricane force wind field.
PRESENT MOVEMENT TOWARD THE WEST-NORTHWEST OR 290 DEGREES AT 13 KT

What is probably meant with ‘sikling’ is ‘sinking’ and then ‘water in the engine room’ and ‘aft part of engine room flooded’. That last part puzzles me a bit, what is aft part of the engine room, the generator rooms? The Z-drive compartment, called Rudder Propulsion Room on the drawing, seems to be flooded also. It is strange that all these compartments were flooding at the same time, but maybe they were not closed really water tight, hard to tell. I have to call Damen I suppose…
