MY 60 metres coule en mer Egée

la Grèce en ruine possède encore heureusement des hélicos de sauvetage....

Il semblerait qu'il s'agisse de Yogi, yacht sous pavillon français, appartenant à Stéphane Courbis.

Hormis le fait qu'il était esthétiquement vraiment superbe ( www.mediterraneanboat.com[...]ogi.php )et que c'était le plus grand yacht sous pavillon français, ce qui est tout à l'honneur de Mr Courbit, il y aura d'autre yacht à emprunter pour la croisière post électorale, celui de Tapie et Dédé la sardine par exemple, mais les 10 m de plus le rendent un peu plus cher à la semaine !!!

ce qui est cher m'est rare, et ce qui est rare m'est cher, mais ces traines-... ne me font pas rêver :pecheur: :-p

L'eau s'est introduite par le système d'échappement à la suite d'une intervention sur un des moteurs.

En fait il y a pas 134 pages car le rapport est en Français et en Anglais. Maintenant il faudrait aussi lire la réponse de Proteskan lors de la sortie du rapport, si l'on veut avoir une vision un peu plus objective.

De toute manière il est toujours intéressant de lire les rapports du MAIB ou du BEA mer.

Intéressant et pas mal approfondi, cet article.

Euh ?!Super article !?

Pour un article censé parler des causes du naufrage il faut attendre le paragraphe AXA assureur pour que l'on commence à y parler des possibles causes du naufrage pour y lire , entre autre : "questions. Que faisaient le Yogi et ses marins expérimentés en pleine mer, alors qu'un navire de plaisance ne sort pas quand le vent souffle au-delà de 5 Beaufort" sic !!
J'ai pas encore fini la lecture mais ca a mal commencé et pour l'instant cela continu mal , ils doivent confondre les engins de plage style pedalo et une unité de 60 m....d'un autre coté peut etre que le pedalo n'aurait pas coulé ?
Fini la lecture de cet article politique qui n'utilise Yogy que comme titre raccoleur pas grand chose pour ne pas ecrire rien , d'info maritimes la dedans .

"et-le-yacht-de-stephane-courbit-sombra"

Une pointe d'humour, un effet de style, une formule emblématique.
Utiliser le passé simple pour explliquer un accident ou une catastrophe, je n'ai encore jamais vu.

Pour vous tous, je recommande après la lecture du Bea Mer la mise au point du chantier. Cet article est en anglais. je ne veux pas le traduire car il ne refléterai peut être plus la position du chantier.
From Dockwalk.The Yard Responds:
Subsequent to the publication of this report, Mehmet Karabeyoglu of Proteksan-Turquoise, issued this statement:

“At a positive level, it is clear that we built and delivered a yacht according to state-of-the-art regulations and rules. The yacht complied with Division 242. However, the report is a limp effort.

“On 21st December 2012, we submitted a detailed response to the BEAmer draft report into the foundering of Yogi. Our comments were carefully considered and prepared with the help of our independent technical expert.

“We are extremely disappointed to see that a significant number of our comments on the draft have been not taken into account in the final BEAmer report, nor are they acknowledged. We do not expect our view to automatically hold sway, but what is disturbing [is] in several places where we pointed out errors in the conclusions drawn by BEAmer, in the final report, we now read altered hypotheses [that] support the conclusions we criticized. The alterations circumvent failings that we identified. For example, in the draft report, BEAmer mentioned that the speed of the Yogi was 16.7 knots at a 60 percent load on the engines. From our own sources, the speed originally cited by BEAmer was close to being correct. We advised them that the loading was incorrect, because at that speed and if the 16.7 knots speed was correct (which we believe it was) then the correct engine loading would be 100 percent; pushing any vessel in those conditions at 100 percent load is not wise. BEAmer decided to maintain the 60 percent loading and reduce the speed of the yacht in [the] final version. One has to ask why? Even though the yachts AIS was turned off, we know exactly what time Yogi left the Dardanelles, there are pilots’ records [that] clearly state when she cleared and we have the captain’s statements as to when the engines overheated. A simple calculation, which takes into account the distance travelled and the time it took to travel that distance, places the speed at around 16.7 knots and, of course, we have the original sea trial reports that confirm this speed can only be achieved at 100 percent load.“We also presented them with photographs taken from the rescue helicopter, which shows the boat upright before the sinking. This photograph is significant, although we don’t want to go in details at this time. Photographs also show aft deck cushions, which were stored in the beach club, floating next to the yacht. This raises the question ‘how did they come out?’ of the beach club where they were stored? We also note that BEAmer accepted that assertion that the crew were able to see one meter of water in the beach club by using the outside watertight door. When we read the draft report, we thought that it was impossible to open that door inwards against one meter of water. We calculated the force needed to open the door. With the assumption there was no water in the staircase, if it is pushed on the handle, which is at the center of the door, 460 kilograms [of] force is required to open the door. If it is pushed on the farthest edge of the door, 230 kilograms [of] force is required. In the final report AFTER we pointed out the amount [of] force needed to open the door, new words were introduced into the report that state there was a lurch to port [that] forced the door open.

“But instead of looking at these human issues in any serious detail, BEAmer has chosen to concentrate on stability issues. It is common knowledge that stability of yachts and ships are based on different scenarios, and following inclination tests by computer software, this is carried out with the inspector of flag authority. If this test is ever doubted, due to a change in weight of the yacht or other loading conditions, this test must be repeated immediately, which can be done at any shipyard anywhere in the world as long as a surveyor from class and/or flag state authority is present.“The yacht was delivered in May 2011 and cruised extensively during the entire summer season. When she was back at the yard for warranty repairs, which were largely painting and other minor issues, initially the owners wanted to repeat the inclining test and, yes, that was on the original warranty list. Yogi was in the shed for painting, and this test could only be carried out in water after the re-launching. When we received the final warranty list, the request for the stability test had been removed by the owners, so this was not performed. We have the emails [that] prove this, including the email from the owners representative with the final warranty list. Finally, following a short sea trial, the warranty list was signed off and Yogi left. There was never ever a suggestion that the yard had refused a stability test and there was no reservation on the warranty list relating to stability. We can only conclude that stability was not an issue, otherwise the captain would not have sailed for months if he had doubts about stability and certainly would not have sailed into poor weather after the warranty work if he had serious concerns about stability. The only inclining test done to date was done by ABS on behalf of the French flag before delivery. It was valid then. It is valid today because no intervening testing took place.

“As you can see, it is extremely alarming to us that BEAmer has concentrated on the initial warranty list, not the final agreed warranty list, which the owners had remove[d] the inclining test. BEAmer was supplied with the complete signed-off warranty list, yet BEAmer have only published a single page of that warranty list and not only that, but that page is incomplete. BEAmer had one full year to complete the report, yet this critical point, which throws a serious allegation at us, was excluded from the draft we were asked to comment on. Even if it is true, as BEAmer claims, that this allegation only gestated in January, they did not seek to verify this serious allegation.“The allegation that important build modifications were not communicated to Flag is nonsense. Elsewhere, [the] report states that the additional keel and the drawings were approved by ABS, who had delegated Flag authority. The draining circuit was an owners’ post-delivery request for which the owner had not sought class approval.

“BEAmer claims that damage stability criteria did not take into account the most adverse situation (two contiguous aft compartments flooded), but they also concede that such flooding contingency is not a requirement of Division 242 and was only the subject of a French flag internal memo that was sent neither to ABS or us.

“Yogi sank in 7–8 hours after the initial incident. It is hard to fathom how the water flooded into three watertight compartments. The yacht had electrical power right up until the final sinking; why weren’t all three bilge pumps operated to try and save the yacht?

“These few issues makes the report extremely disappointing, and we do not understand the process that BEAmer used to collect and verify evidence. However, BEAmer’s general recommendations do merit consideration, even if several of their 10 key points are not supportable by evidence or contradict what BEAmer themselves have written elsewhere in the report.”

Pour rebondir sur longcours, l'équipage est certainement compétent. le milieu est restreint et les gens incompetents sont rapidement écartés.

Toutefois, un capitaine 3000 ou un chef 3000 dans ce contexte est en général sorti du rang. Il a tout appris sur le tas, mais n'a souvent que de vagues notions des détails de la réglementation (experience personnelle comme inspecteur de classe et de pavillon, j'ai plus souvent donné cours que vraiment pénalisé des gens. Ce n'est pas leur faute, la profession le rend possible)

Le chef de projet, si compétent qu'il soit, aura sans doute plus planché sur la table du salon hydraulique et le conditionnement d'air que sur des questions structurelles, en toute logique car cela devrait être couvert par la classe.

Le rapport apporte péniblement peu d'éléménts nouveaux par rapport aux commentaires des professionels immediatement après l'accident; Comme d'habitude, les mesures préconisées sont soit déja en place, soit impossible a appliquer en pratique.

Il serait intéressant d'avoir le rapport d'accident et les actions prises par Atalante Yachting... ou ont-ils coulé avec Yogi
:alavotre:

Intéressant à lire, ce rapport.

Ce qui me surprend : ajout de 30 tonnes de lest pour compenser des modifs sur les superstructures mais qui n'apparaissent pas sur les plans, ajout de portes au raz de la ligne de flottaison, une étude de stabilité demandée par le capitaine qui n'a jamais été réalisée, modifications des compartiments arrières non reportés sur les plans, un compartiment qu'on décide de cloisonner pour en faire deux, des échappements immergés pour éviter les salissures mais sans les capteurs de contrôle, ...

Ca me rappelle les improvisations de dernière minute sur les chantiers fluviaux après le passage d'un expert (et quelques arrangements vite vus avec le client comme pour faire plaisir à tout le monde !) pour des conséquences extrêmes moindres.
