Dear Shipowner/Operator/Master/Recognized Organizations:

The purpose of this Advisory is to provide guidance regarding implementation of the global Sulphur limit which took effect on 1 January 2020.

As of 1 March 2020, the limit for Sulphur in fuel oil used or carried for use on board ships operating outside designated emission control areas (ECA) was reduced from 3.50% m/m to 0.50% m/m (mass by mass).

Since the introduction of the global Sulphur limit, the Liberian Administration has responded to numerous questions related to preparation, implementation, operation and enforcement, including to such questions pertaining to Exhaust Gas Cleaning System (EGCS).
