SECA & ECA
Amendments to MARPOL Annex VI for ships operating within a Sulphur Emission Control Area (SECA) came into force on 1 July 2010.
As of that date vessels operating within the two existing SECA’s, namely the Baltic Sea Area and North Sea including the English Channel, must produce no more than 1.0% Sulphur Oxide (SOx) by mass, a reduction from the previous limit of 1.5%.
MARPOL Annex VI requires that ships within a SECA comply with the SOx emission limit wither by consuming low Sulphur fuel or by utilising an exhaust gas cleaning system or any other technological method that has been approved by the vessels Administration.
The “2009 Guidelines for the Sampling of Fuel Oil For Determination of Compliance with the Revised MARPOL Annex Vi” also came into force as from 1 July 2010. A copy of the Guideline can be found in Annex 7 of MEPC.182(59).
Under the International Convention for Prevention of Pollution from Ships (MARPOL – Annex VI), with effect from 1st August 2012, all ships calling US ports are required to change over to low sulphur fuel oil (LSFO) for general steaming and usage in US waters, under co-ordinates prescribed in Annex VI of the new MARPOL.
