The new MARPOL Annex VI ultra-low-sulphur fuel oil regulations
coming into force as of 1 January 2015 introduce a significant regulatory
change with respect to the maximum permissible content of sulphur
(S) in marine fuels in designated sulphur emission control areas
(SECAs), from max. 1.0% S to max. 0.1% S.
This change makes it even more important than before to know what
is bunkered and to keep the crew informed on specific challenges
and the appropriate actions. Careful monitoring of the cylinder condition
must also be carried out and followed by the proper action.
The enclosed paper: “Guidelines for Operation on Fuels with less
than 0.1% Sulphur”, provides guidelines and recommendations on
how to ensure safe and reliable operation on fuels with less than
0.1% sulphur. The following key subjects are described:
• Low-BN cylinder oils – how and when to apply low-BN oils
• ISO 8217 and new fuels with less than 0.1% S (ULSFO) – key characteristics
of different standard fuel grades.
• Viscosity and fuel pump pressure - the viscosity of the fuel should
be kept above 2 cSt at engine inlet, and the fuel pumps must be
kept in adequate condition.
