2.1 Purpose
2.1.1 The purpose of these guidelines is to specify the requirements for the
testing, survey certification and verification of EGC systems under regulation 4 of MARPOL Annex VI to ensure that they
provide effective equivalence to the requirements of regulations 14.1 and 14.4 of MARPOL Annex VI.
2.1.2 These guidelines permit two schemes: Scheme A (unit certification with parameter
and emission checks and Scheme B (continuous emission monitoring with parameter checks).
2.1.3 For ships which are to use an exhaust gas cleaning system in part or in
total in order to comply with regulations 14.1 and/or 14.4 of MARPOL Annex VI, there should be an approved
SOX Emissions Compliance Plan (SECP).
2.2 Application
2.2.1 These guidelines apply to any EGC unit as fitted to fuel oil combustion machinery,
excluding shipboard incinerators, installed on board a ship.
