ClassNK Issues 2020 Switchover Guidance


Japan’s Class NK is the latest industry stakeholder to add to the glut of guidance on the upcoming global 0.50% sulfur cap on marine fuel.

Booklet for Shippers

The Classification Society says its “Booklet for ship crew members: Precautions concerning change-over to 0.50% sulphur compliant fuel oils” outlines potential risks for ship crew members responsible for operations in the change-over from conventional fuel oils to compliant fuel oils and measures to mitigate them.

Focus on cold flow properties

The booklet provides ship crew members on-board who bunker and actually use compliant fuel oils with information focusing on the ‘compatibility’ and ‘cold flow properties’ of such fuels as well as associated risks and measures to mitigate such risks,” it says.

References on sludge disposal

In addition, there are relevant recommendations and product leaflets provided by several chemical manufacturers pertaining to sludge dispersants and sludge solubilizers are attached to the booklet as references.
