Marinised

Marinisation (also marinization) is design, redesign, or testing of products specifically for use and long-term survival in the harsh marine environment. This is done by many manufacturing industries worldwide including many military organisations (especially navies). The main challenge is for the engineers who design the product from the scratch. Every parts needs to be designed in order to fit to the marine environment and then to resist to its "natural attacks".

There are three main factors that need to be considered for a product to be truly marinised.

These three factors are a constant in the marine environment. Even on a dead calm day all three factors will still apply. This includes non salt water marine.

Marinised electronics are electronics that use one or more of the following protection methods. In most cases more than one method is used:

Marinised metals include some of the following examples:

Marinised batteries are usually Gel battery or sealed maintenance free battery. Not using marinised batteries in salt water can be deadly in an enclosed environment for many reasons:
