Certificates and Approvals as signs for market development?

Since the rules for controlling the discharge of living organisms from ships’ ballast water in U.S. waters entered into force on June 21, 2012, industry and authorities have needed three years to implement the requirements of the document in a compliant manner and to issue the first approvals. The number of certificates issued by the USCG has been increasing continuously since then, but a tripling as in the period 2016 to 2019 will not be achieved by the end of 2020.


Nevertheless there is a lot of movement in the market: Currently 38 BWMS from 30 different manufacturers have been approved, compared to 35 systems from 27 manufacturers in September 2020.  Further systems are currently being tested, but the number of BWMS under review is decreasing.


How do you think the BWMS market will develop? Is there still potential or are there already first signs of market saturation?
