[en] International Maritime Organization (IMO) has developed a legislation called ‘International Convention for the Control and Management of Ships Ballast Water and Sediments’ to regulate
the discharge of ballast water and reduce the risk of introducing non-native species from ships
ballast water. To reduce this risk, there are various treatment methods available in the market.
These treatment systems must be approved by the administration in accordance with IMO
guidelines. The main objective and scope of this work is to review and compare IMO and USCG
requirements in terms of type approval, inspection and certification requirements, to describe
and compare different treatment methods and to discuss about selection of appropriate
technology based on various factors such as safety, environment, practicability, cost and
biological effectiveness in terms of effective removal or inactivation of harmful aquatic
organisms and pathogens in ballast water. In this thesis work, some of the alternate and
innovative ballast water management systems have been discussed as well. In addition to that,
a case study about retrofitting ship has been conducted. This work has been developed in
association with Westcon Design Poland, to serve as a reference covering various aspects of
ballast water management and it can provide different perspective to all stakeholders such as
classification societies particularly to Overseas Marine Certification Services (OMCS Class),
ship owners, design offices, shipyards, treatment system manufacturers and others who are
involved in the implementation of the convention. Based on data collected from various sources
associated with this subject, comparison and analysis at different stages of this work,
conclusions and recommendations have been obtained to serve the purpose for which this work
has been carried out.
