Portland Port is working with international shipping association BIMCO and industry partners to launch a hull underwater cleaning standard. This will help stop the spread of invasive species around the world on ships’ hulls.
Underwater cleaning is only allowed in a few locations around the world. This may increase emissions from shipping as fouling increases the fuel consumption or in worst case force the ship to change its route.
The standard will ensure that the result of the cleaning is in accordance with a set of specifications, that the environmental impact of the process and coating damage is controlled and that the cleaning process is planned, safe and effective.
Part of the standard will address how to ensure that the paint is not damaged during cleaning, and that debris and wash-water is collected in a practicable and sustainable manner.
