Why Are All These Superyachts Catching on Fire?

From St. Thomas to Abu Dhabi, tens of millions in luxury yachts have recently gone up in flames.

The article on Bloomberg web http://www.bloomberg.com/news/articles/2016-04-11/why-are-all-these-superyachts-catching-on-fire

Takes me to write this lines to give a new vision from my point of view.

What is going on during a new build or refit? You are sure as owner that when you are buying a Megayacht from the most recommended and prestigious Yards with projects and materials approved from the famous class organizations, that everything is save and all risks are calculated to zero

                                               No it isn`t and I will show you why

Only I will take some electrical examples provided by E Yacht Projects taken from one of the most famous and expensive MegaYacht of 100m and build by the highest standards by one of the most famous Yards from North Germany and approved by an big class organization.

When the standard organization get all the drawings and schematics of a new build or refit the yard also provide the certificates of the materials, this means that the yard can only use electrical material with type approval.

 

1.       Example a normal Breaker with type approval used in hundreds of yachts in electric cabinets. This breaker is installed in all circuits for 230V AC and 415V AC and it is good and approved for this use.

But now the surprise also it is applied in all 24V DC circuits and cabinets. This is a use where it is not made for and not approved and it is an big risk for an electrical fire, because the breaker did not trip in case of short or overload, the breaker is not made for DC use. The standard organization don`t see, don’t check and don`t have the know how to see this big construction fault. Also the Yard with his high standards don`t see this faults. (Picture 1&2)

   ( all this breakers are to change)

 

 

 

2.       An distribution in an AC Panel to give power to ten consumers with cable diameter of 2,5mm2. The typical DIN Rail connections where the big main cable of 16mm2 comes in to the first connection and then normaly is distributet to the consumers, but only  one cable of 2,5mm2 is connected to the main and gives service to the ten consumers. (Picture 3,4, 5&6) the result this cable get to glow by overload and can cause a big fire.

3.       No Ventilation of electrical cabinets. The owner and the crew is is fine by 18ºC when outside are tropical conditions but the cabinets are working in temperature ranges of 70º to 100ºC, you only need to wait for the possible fire. (Picture 4)

Solutions

You will find this problems on your Megayacht by carry out an Thermografical survey

The boat yards need to contract professionals in the special sectors a Naval Engineer cannot know this special things.

The classification companies have the same problems they contract Naval Engineers but in the university studies they only make an overview of electrics.

The insurance companies need to take care of an independent survey before sign the police.

Megayachts and Shore Power

 2016by MYS

 

OneOcean Port Vell and his Habour Capitan Anders Pehrson have had the vision in the future and have installed in the "Moll d`Espanya Quay" Shore conections up to 1250A. More and more Marinas when they need to renuve their consessions are asked to comply  Marine and Habour envirovments ,and provide posibility to Megayachts to conect to Shore Power to avoide noise and exhaust polution.

We provide Shorepower Transformers or Shore Power Converters up to 2000A with automatic phase and voltage adjustment.
