Are there other MARPOL Annex VI requirements that apply to engines?
There are two other requirements for compliance with Annex VI. First, each engine must have a Technical File. This document is prepared by the engine manufacturer and contains information needed to inspect the engine to verify compliance. A paper copy of this document is required to be available onboard the vessel, although in the future an electronic copy may be sufficient. Second, each engine must have a Record Book of Engine Parameters. This is a document for recording all parameter changes, including components and engine settings that may influence NOX emissions. This information is used during vessel surveys and inspections, to make sure the engine has been complying with the NOX limits. The vessel owner must make sure the Record Book is always accurate. If the settings on the engine do not match those in the record book, an engine survey may include a more time-consuming investigation and, potentially, onboard measurement of NOX emissions.
