One of the company's characteristics : Consulting for analyzing of organisms in ballast water & ballast water treatment equipment development

Since the late 1980s, ballast water from ships has been recognized internationally as a major factor in the transfer and ecosystem of alien species. The Ballast Water Management Convention was adopted at the International Maritime Organization (IMO) conference in 2004.

We are the only testing laboratory in Japan accredited to ISO/IEC17025 for all categories of bioanalysis in ballast water and have extensive experience in performance testing and permit application services for ballast water management systems (BWMS).

We also conduct research on the invasion of these alien organisms and provide administrative support for international conferences and committees related to ballast water management.
