Ballast Water Management and Reseach

Welcome to Gollasch Consulting !

We are an independent service provider founded 1997 as an initiative of Dr. Stephan Gollasch. Located in Hamburg, Germany - the busiest German port - we provide services related to marine research and technology with a focus on ballast water. Since 2015 we are member of the Conctrol Union Certifications (CUC) U.S. Coast Card accepted Independent Laboratory to test ballast water management systems. During the >150 vessel voyages for shipboard tests of >20 ballast water management systems we visited all inhabited continents and took >1200 ballast water uptake and discharge samples.  

Our main work focus includes: 

  • development of indicative and detailed ballast water sampling strategies;
  • evaluation of indicative and detailed ballast water sample analysis tools;
  • general support during the certification process of ballast water management systems
  • preparation of Basic and Final Approval dossiers according to the GESAMP-BWWG Methodology; 
  • training of port State control for compliance control with ballast water management standards; 
  • shipboard tests of ballast water management systems according to IMO und USCG requirements; as well as 
  • commissioning tests of ballast water management systems


Our research interest becomes clear due to our involvement in these predominantly EU-funded projects:
