The American Bureau of Shipping (ABS) has published the ABS Advisory on NOx Tier III Compliance to provide best practice for IMO Tier III compliance for newbuild vessels and retrofitted ships.
The advisory includes an overview of available technologies, evaluates considerations for the selection of compliance options, and outlines the process for statutory and class approval. It also details best practices for installation and integration of exhaust emission control systems and challenges typically encountered during their operation.
ABS has also launched two supporting notations. The new NOx notation recognises vessels with engines complying with appropriate MARPOL requirements while the new LEV notation recognizes low emission vessels equipped with engines complying with EU regulations.
