Club would like to bring to the attention of Members that the IMO has issued the RESOLUTION MEPC.387(81) providing Interim Guidance on the Application of the BWM Convention to Ships Operating in Challenging Water Quality (CWQ) Conditions.  

Ballast Water

The primary purpose of the Guidance is to assist ships in planning for compliance with the BWM Convention and the D-2 discharge standard when a type-approved Ballast Water Management System (BWMS) that has been properly installed, operated, and maintained encounters operational limitations or has difficulty meeting operational demand in challenging water quality (CWQ) conditions.

The Guidance is also intended to guide Administrations, port States and BWMS manufacturers in providing appropriate support and oversight to ships before, during and after CWQ operations.

The Guidance is intended to reaffirm the conditions for temporary non-penalization agreed in operative paragraph 4 of Resolution MEPC.290(71) relating to non-compliance of a ship with the performance standard in regulation D-2 following the use of a BWMS during the xperience Building Phase (EBP).

Members are advised to seek details of the most up to date information through their flag Administration.
