![]() | VENT 7 - STRUCTURE |
The essential thing in design of underwater vehicles is to use materials with a high strength-density ratio. Because we are dealing with sea-water, and more specifically vent fields, there are several environmental conditions taht go into choosing a material to use for the auvs and rovs. Metalals, and other materials tend to corrode in the sea-water due to electro-chemical mechanisms. There are five main ways corrosio can occur:
