Safe at sea – protecting your sailing yacht from overvoltages


Here, the masts of a ship are by far the highest objects and that means the risk of being struck by lightning is also higher. I have experienced storms often enough and it was never a pleasant feeling because you are always at its mercy. If the ship is not prepared properly as far as lightning strikes are concerned, it is particularly unpleasant feeling because you know that you have not done everything that you could have done to protect the crew and the ship itself. The communication must also function properly. The navigation is important if you are a long way away, and even the engines do not work properly without the electronics which means it is extremely important to avoid a failure or to ensure that the electronics are not damaged by a lightning strike. That is the reason why we have a closed lightning protection concept that also includes both external and internal lightning protection. The external lightning protection takes care of the mast, the walls, and the stage, everything connected with the hull of the ship below the water line. That is the external system; we also have the internal lighting protection. The internal lightning protection, here we have attached a surge protection arrester to the electronic devices in order to arrest and discharge any induced voltage that may got into the lines and therefore to protect the electronics against surge voltage. After we implemented the lightning protection concept here on our new ship, I always say when a storm is approaching: let’s go on board because that’s the safest place. And that is really the case when everything has been carefully planned and carried out and therefore you have have the best protection. We did this together with Phoenix Contact and took advantage of the experience that Phoenix Contact could offer in the area of fine protection and industrial electronics as well as the experience gained from lightning protection for wind power plants and photovoltaic systems, we implemented this concept and… …you can see, it’s finished, it as a big project but we’re happy.
