(http://www.MaritimeCyprus.com) Since the Ballast Water Management Convention came into force last September, port-states have not been homogeneous in dealing with contingencies where ship operators were unable to carry out ballast water exchange.
In light of the entry into force of the IMO’s Ballast Water Management Convention (BWMC) as well as the step change in enforcement of the United States Coast Guard (USCG) regulations on ballast water, Shipowners are now more frequently using their BWMS to manage ballast water to meet the necessary discharge standards. However, while the BWMS installed have been type approved in accordance with either or both the IMO and USCG requirements, it is estimated that up to 60% of BWMS installed are not operating correctly.
As such, and when vessels are delivered with BWMS or retrofitted to comply with BWMC or USCG Regulations, it is important to also amend the Ballast Water Management Plans (BWMP) to ensure a practical and realistic set of contingency measures is included. With Port States, Flag Administrations and Class Societies still considering the most appropriate options in the event of a BWMS failure, it is hoped that the contingency measures identified in this document, together with the procedures recommended, will provide a clear indication of what to expect from the vessel under such circumstances.
