DHI is an independent, international consulting and research organisation established in Denmark and today represented in all regions of the world with a total of more than 1,000 employees. Our objectives are to advance technological development, governance and competence in the fields of water, environment and health. DHI works with governmental agencies and authorities, contractors, consultants and numerous industries.
DHI provides independent performance evaluation of ballast water management systems (BWMS) for the approval process. DHI has no involvement, intellectual or financial, in the mechanics, design or marketing of the products and technologies that are being evaluated.
To ensure that DHI’s tests are uncompromised by any real or perceived individual or team bias relative to test outcomes, DHI’s test activities are subject to rigorous quality assurance (QA), quality control (QC) and documentation. DHI’s quality management system is certified according to ISO 9001 by Det Norske Veritas (DNV). The certification is facilitated by the implementation of the DHI Business Management System.
For an application for final approval, the IMO International Convention for the Control and Management of Ships’ Ballast Water and Sediments /1/ requires a performance evaluation of BWMS according to the principles laid down in Resolution MEPC.174(58) /2/, generally referred to as the IMO G8 guidelines, and, for systems that make use of active substances, also Resolution MEPC.169(57) /3/, generally referred to as the IMO G9 guidelines. The purpose of the performance evaluation is to assure that BWMS approved by administrations are capable of meeting the ballast water discharge standard in Regulation D-2 /1/, also known as the IMO D-2 standard, in land-based and shipboard evaluations and do not cause unacceptable harm to the vessel, crew, environment or public health. The United States Coast Guard Standards for Living Organisms in Ships’ Ballast Water Discharged in U.S. Waters /4/ (§151.2030) establish a ballast water discharge standard similar to the IMO D-2 standard. According to the U.S. Coast Guard, the test set-up in land-based test cycles of BWMS must operate as described in the ETV protocol /5/.
DHI-Denmark has recently received the U.S. Coast Guard recognition as Independent Laboratory together with DNV. DHI is accredited according to EN ISO/IEC 17025 for the analysis conducted in relation to performance evaluation of BWMS.
