ClassNK Updates Scrubbers Guidelines
Classification society ClassNK said it has released the second version of its Guidelines for Exhaust Gas Cleaning Systems. Based on the first version Guidelines released in August 2014, the latest version includes the results of joint research and testing on actual Exhaust Gas Cleaning Systems. In an effort to reduce SOx and PM emissions from ships, MARPOL Annex VI limits the maximum allowable amount of sulphur contents of fuel oil used onboard globally, as well as place stricter requirements in geographically defined Emission Control Areas (ECA). Last October it was determined that stricter global sulphur limit of 0.5 percent is to be started on 1 January 2020.
Keeping a Tight Lid on Tier III & Sealing Solutions
With more than 90 percent of global trade carried by sea, shipping is a major battleground in the reduction of emissions. Tier III is the latest emission standard pertaining to NOx emissions from marine diesel engines. Tier IV is expected to come into effect for 2020 – with engine manufacturers already seeking sealing components to future-proof engines well into the next decade. Here we explore challenges faced by diesel engine operators in the face of Tier III, and how the correct selection of sealing materials could deliver better performing solutions.
