My Song - lost in transit

Re: The loss of a beautiful superyacht

They mention that her draft is 7 metres - but she does have a lifting keel.
Even so, her displacement is 105 tonnes - how did they lift her on board this cargo ship Brattingsborg?
I very much doubt that her two cranes combined together would be able to lift this weight - never mind the effect on her stability!

105 tonnes isn't much of a challenge to a mobile crane. Ainscough will rent you a 1000-ton one, for a price. Needs a ground survey, mind you ...

Ah, but that is in Britain - there are not very many (if any) mobile 1,000 ton cranes knocking around in the Caribbean.

And if money is no object really, why did they chose to load her on to such a small ship (relatively - My Song is 40 m, the ship is 130 m), compared to a dedicated yacht transport vessel where they drive the yacht into the dry dock rather than lifting her on board and storing her on the hatch covers?
These folk DYT had a ship sailing from the Caribbean to the Med at the same time.

The Yacht Express vessel is twice the size of the Brattingsborg - and the yacht is sitting inside the ship, not perched high up on the hatch covers.

Thanks for that picture. I would like to hear from Bajansailor and other surveyors, but looking at the picture and considering the report that the Brattingsborg had called at Palma, I strongly suspect that she had a high GM - was very stiff - and the My Song’s lashings were not up to it. Specifically I bet the Brattingsborg’s Mate didn’t re-run his stability calcs after discharge of other yachts at Palma.
 
Re the lashings, most of them appear to be pretty much vertically downwards or only slightly angled - very little or no diagonal bracing.
It would have helped a lot re the moment of inertia of My Song if they had taken the mast off first but this would have been a very big job indeed.
And with Brattingsborg's GM being relatively high, the roll period of the ship would be much less compared to if the GM had been less (sometimes you can have too much stability) - it only takes one or two lashings to break before the yacht would have been literally hurled over board on a good roll.
 
I wonder also if the whole rigging/chainplates is correctly dimensioned for being transported like that.
I mean, the ship pitch and roll would accumulate a not irrelevant kynetic energy on the mast, the hull being solidly strapped to the ship, the snatch loads at the end of each roll half-cycle might well be a lot above those the boat experiences while floating on water, where increase in heeling can absorb a lot more. That mast must be what? 50ish m high? Add possibly another 10-20m above the CG of the ship, that s a huge leverage.

I defer to your knowledge on that, but I just gave 1000T as an example of how big they go. Smaller would do fine. I see that Jamaica has a nice new Liebherr LHM600 ...

https://www.khl.com/news/jamaica-gets-liebherrs-largest-harbour-crane/122108.article

... which despite what the article says, is actually good for 208T

https://www.liebherr.com/en/int/pro...ment/mobile-harbour-crane/details/lhm600.html

I suspect that the 103T mentioned is at full extension, reaching over 8 rows of containers.

Edit: There seems to be a 104T Liebherr on Barbados.

Re: The loss of a beautiful superyacht

Ummm yes, but the yacht was loaded on board the ship in Antigua according to a report here -
https://www.vesseltracker.com/en/Ships/Brattingsborg-9488035.html
She weighs over 100 tonnes - and I doubt that Antigua has a mobile crane big enough to lift something this heavy.
A bit more googling found that the ship is owned by Weco Projects (formerly Nordana) - and her deck cranes are 150 mt capacity each, so one of them would have been sufficient for lifting her on board.

Re: The loss of a beautiful superyacht

MV Brattingborg has 2 x 150 MT cranes that on tandem lift could easily lift 100 MT from alongside. This is not a significant factor in the incident.
 
Re: The loss of a beautiful superyacht

My outfit has had a a near sister on timecharter and I've loaded her, but not with yachts ; you would normally tandem the cranes for that lift to give good positioning. I've got a very definite hunch about what happened here.

Re: The loss of a beautiful superyacht

The ship was transporting quite a few yachts in a movement organised by Peters and May.

They have issued a statement to say their initial investigations would suggest My Song was lost overboard after a collapse of the shipping cradle, which was provided by the yacht owner and certified as suitable for shipboard use. The cradle was assembled and secured by the yacht's crew.
 
Re: The loss of a beautiful superyacht

Here is a link to the statement mentioned by Motor Sailor -

https://www.boatinternational.com/y...t-baltic-130-custom-superyacht-my-song--40591

And here is an excerpt from this statement :

"A full investigation into the cause of the incident has been launched, however the primary assessment is that the yacht’s cradle (owned and provided by the yacht, warrantied by the yacht for sea transport and assembled by the yacht’s crew) collapsed during the voyage from Palma to Genoa and subsequently resulted in the loss of MY SONG overboard. I will add that this is the initial assessment and is subject to confirmation in due course."

I've every confidence in Peters and May.

Yacht said to be in bad condition goes overboard from cradle supplied by yacht's owner, eh? Absolutely nothing remotely suspicious about that.
 
Re: The loss of a beautiful superyacht

Sorry but that's just rubbish. You're referring to the original translation which is BS. The boat was in perfect condition when loaded and is now wrecked (bad condition). It was due to race next week so how could it be in "bad condition"?
