Ammonia as a marine fuel

Machinery


Ammonia has attracted wide interest as a source of zero emission fuel for shipping. Ammonia has the key benefit of being easier to store than hydrogen, i.e. nearly identical to propane (LPG) at low pressure under ambient conditions. Hence, the cost of storage per energy unit is significantly cheaper than either hydrogen, electricity in batteries or LNG.

Corrosion protection of cargo oil tanks of crude oil tankers

Structural


Crude oil is a complex mixture of substances at varying ratios and in most cases contains at least some salt water. Even after desalination some of this brine remains dissolved in the crude and gradually sinks to the bottom of the cargo oil tank during transport. The corrosive nature of salt, along with microorganisms and other aggressive substances contained in the cargo oil, causes rust, most notably in the form of pitting, which are cavities in the steel that deepen over time.
