INTERTANKO’s Guide (First Edition, 2012) on the Selection and Installation of Ballast Water Management Systems for Tankers has been developed to assist tanker owners during the selection, assessment and installation of Ballast Water Management (BWM) systems for existing and newbuilding tankers. It has been developed using experience and guidance from INTERTANKO Members on the Environmental Committee and INTERTANKO’s Safety, Technical and Environmental Committee (ISTEC). It is therefore the product of research by several separate tanker operating companies and their technical teams who have been through the process of considering which BWM systems are appropriate for the tankers within their fleet.
