Abstract
AbstractThe introduction of invasive aquatic species in new environments has been identified as one of the four biggest threats to the world's oceans causing serious threats and harm to both ecology and human health. There is a major exchange of ship’s ballast water over longer distances between continents and regional seas, and it has been known for decades that ballast water transfers organisms to new ecosystems, where the strongest, most aggressive and adaptable species can survive and become invasive under favourable conditions. The focus of the research is to study available ballast water control technologies to determine their suitability and effectiveness in the reduction of harmful aquatic organisms and compounds in the Baltic Sea.
Highlights
To ensure the buoyancy, stability and manoeuvrability of ships ballast water is required
The aim of BWM 2004 is to govern the process of ballast water exchange and to reduce the risk of invasive aquatic species
Based on the requirements and guidelines stated by BWM 2004, a ballast water and sediment treatment system should be installed on ships by September 8, 2024 latest
Summary
Stability and manoeuvrability of ships ballast water is required. As the ships become more technologically advanced and larger, cargo turnover and, t he amount of taken and discharged ballast water increases too. Ship’s ballast water and sediments are transferring more harmful organisms [1]. To prevent the spread of such global and environmental problem the International Convention for the Control and Management of Ships’ Ballast Water and Sediments (BWM 2004) adopted by the International Maritime Organisation (IMO) in 2004 entered into force on September 8, 2017. Based on the requirements and guidelines stated by BWM 2004, a ballast water and sediment treatment system should be installed on ships by September 8, 2024 latest. The study of evaluation of treatment methods to ship ballast water is relevant
