These industries help the world spin because the most shipments are made on water. As demands the cables must be resistant to the sea salinity but also to mud. For some aspects also the halogen free and fire resistance features are important in places where the protection of processes is mandatory. It is required a high flexibility of the cables because the usual installation of these cables is in narrow spaces. The continuous search for a reduction of the weight is also affecting the construction of the marine cables and this is driving forward the improvement of the used materials.
The involvement of the human lives makes this industry one of the most demanding in the certifications sector. No cable should be installed in a ship without prior testes made by a certified laboratory. For a ship there are needed numerous types of cables as the ship needs power, signal transmission, fire systems, lighting, etc.
