On the use of aluminium in shipbuilding

Abstract

The use of aluminium in shipbuilding dates back to 1890 and its use has increased over the years. It is now possible to make all-aluminium ships, meeting the same performance criteria as steel constructions. In a context where the total cost of ownership of a vessel prevails on the initial purchase cost, aluminium ships represent the most economical alternative. The superior mechanical properties, lightweight and corrosion resistance of aluminium alloys imposed their use in shipbuilding and in the fabrication of components for offshore platforms. By using aluminium, the naval architects can design ships and boats with high-speed capability, long life, high payloads, and low maintenance costs, as well as a high recycle value.
