Regulations Coming into Force on 1 February 2025

Starting 1 February 2025, amendments to Appendix II of the Ballast Water Management (BWM) Convention will be implemented, bringing significant updates to the Ballast Water Record Book (BWRB). These amendments aim to address common deficiencies and improve the accuracy and clarity of ballast water reporting.

Amendments to Appendix II of the BWM Convention

The Ballast Water Management (BWM) Convention, under Regulation B-2, mandates that ships maintain a Ballast Water Record Book, which must contain specific information regarding ballast water operations. Over time, the most frequently reported deficiencies during Port State Control (PSC) inspections have been related to incomplete or inaccurate entries in the BWRB.

To address these issues and improve compliance, Appendix II of the BWM Convention has been updated to revise the format and information requirements of the Ballast Water Record Book.

Key Changes to the Ballast Water Record Book (BWRB)

•Clarification and Enhanced Information: The revised Appendix II provides clearer guidelines on the required entries in the BWRB, helping ship operators better understand what information must be recorded during ballast water operations.

•Improved Record-Keeping: The updated format of the BWRB ensures that ships maintain more accurate and comprehensive records, reducing the risk of deficiencies being flagged during inspections.

•Implementation Date: The new format for the BWRB will become mandatory for ships on 1 February 2025, requiring all vessels to comply with the revised record-keeping and reporting requirements.

Guidance and Compliance

Members are encouraged to refer to BWM.2/Circ.80 for detailed guidance on how to properly maintain the new Ballast Water Record Book and to ensure their vessels are in compliance with the updated requirements starting 1 February 2025. This will help mitigate any potential non-compliance issues and ensure smoother PSC inspections.

Regulations Coming into Force on 1 May 2025

Starting 1 May 2025, significant amendments to MARPOL Annex VI, specifically Regulation 14 and Appendix VII, will come into effect. These amendments pertain to the Mediterranean Sea’s designation as an Emission Control Area (ECA) for sulphur oxides (SOx) and particulate matter (PM), impacting vessels operating in or transiting through this region.

Mediterranean Sea ECA Designation

The Mediterranean Sea was officially designated as an ECA for SOx and PM as of 1 May 2024. However, the regulatory requirements will only become mandatory on 1 May 2025. This means that, beginning on this date, ships navigating the Mediterranean Sea must comply with stricter emissions controls to reduce the environmental impact of shipping operations in the region.
