Class notation that reduces the environmental impact from ships due to air emissions and sea discharges

Purpose

Environmental legislation will become increasingly strict over the next few years as regards emissions to air (such as SOx and NOx) and sea pollution (such as bilge and ballast water and waste oil). By adopting the CLEAN Notations, the ship owner and operators choose to comply with environmentally friendly regulations and a set of criteria in order to clearly demonstrate to customers and authorities that the company’s policy is to be environmentally proactive.

Benefits

For owners interested in promoting an environmental profile, the notation confirms a higher environmental standard. The company’s brand will increase in value and the public image will be enhanced due to the company taking active pro-environment steps and assuming responsibility.

Features

The class notation contains requirements stipulating how to control and limit operational air emissions and sea discharges. The Rules state an environmental approach to installed equipment and arrangements on board, such as:

• Combustion machinery emissions (NOx and SOx)
• The use of refrigerants
• Limits on the use of TBT-based antifouling
• Sewage and other waste water treatment
