Ballast Water Management 6th Edition

In February 2004, the International Convention for the Control and Management of Ships’ Ballast Water and Sediments was adopted but has not yet been ratified. This 6th edition of the WPG Guide to Ballast Water Management (BWM) provides an up-to-date guide to the current state of international and national ballast water legislation, the requirements necessary for a ship to be compliant and the treatment options available. There is also a comprehensive and descriptive section containing those BWM systems that can be used on board ships with IMO Type Approval from a certifying body and systems accepted for use in waters of the United States. Currently ballast water exchange (BWE) is used to minimise the risk of transferring invasive organisms in ballast water, but when the BW Convention is ratified, the next stage of managing ballast water will be when the D-2 Performance Standards come into force. 
This 6th edition of the book covers the key issues with ballast water management today including:


The complexities of ballast water legislation.

IMO legislation is not ratified and decisions are pending. United States regulations are in force now for some vessels discharging ballast water in US waters. There are many different BWMS that have already received IMO Type Approval, and many of these have been accepted for temporary operation in US waters, but none that are currently USCG Type Approved. The intent of a treatment system manufacturer to apply for USCG Type Approval could be an important deciding factor for a shipper in which BW system to choose.


The knowledge of what a shipowner will need to take into consideration before choosing a BWMS.

Shipowners face a difficult process of choosing a BWMS. The requirements of a vessel depend on many factors including the space on board, ballast water capacity of the vessel, amount of energy necessary to operate the system, compatibility with existing systems on board, crew safety, operating time and cost.


Planning what, where and when to install.

The retrofitting of a BWMS takes longer and is more complicated than integrating the system into a newbuild. This makes the process more expensive. Waiting too long to commit to an installation may mean that BWMS manufacturers cannot meet demand, dry-docking time is not available for installation or compliance extensions are not applied for in time. This will result in compliance schedules not being met.


The ability to remain compliant.

Since an early test for compliance by Port State Control is to check for crew knowledge and BWMS operational capability, shipowners must make sure that they and their crews understand the systems they are purchasing.


This book provides comprehensive information on the above issues and is updated to MEPC 68 decisions.
