Ballast water treatment system installation cost assesment

The possibility to transfer invasive species from ship ballast water between different world regions today is clearly recognized. Also, it is quite clear that expected increase in world seaborne trade in the future will make the problem even more serious1. Consequently, the International Maritime Organization IMO adopted the International Convention for the Control and Management of Ships Ballast Water and Sediments (BWMC) in February 2004. The main goal is to prevent the transfer of invasive species within different world regions by ballast water and sediments. The BWM convention will enter into force on 8 September 20172. According to regulations of the Convention, all new and existing ships in international trade are required to install Ballast Water Treatment System (BWTS). Although there were no such systems just a few years ago, the requirement in very short time created a completely new market. The main stakeholders in the market are ship owners, BWTS producers, and shipyards. Total costs include purchasing costs, installation costs, operating costs and maintenance costs3. The paper presented analyses at most the Ballast Water Treatment System installation costs as well as other factors that have a relevant impact on the installation cost. In order to estimate the extent of the costs and efforts expected by different stakeholders, at the beginning of the paper the structure of the global fleet will be shown. In the second part of the paper, the basic parameters determining installation costs will be analyzed. Finally, at the end of the paper the validity of data, collected from different sources, will be examined as well as overall cost assessment. In the conclusion, the future market dynamics is estimated as well as possible impacts on the technology development of the ballast water treatment systems caused by estimated market forces. Key
