Ballast water compliance monitoring

The entry into force of the Ballast Water Management Convention (BWC) in September 2017 after years of debate provided the maritime industry with a framework to deal with the increasing threat of invasive aquatic species.  To date, 74 states have ratified the BWC, representing more than 75% of the world’s merchant fleet.  CTG is working closely with regulators including the IMO and port authorities as a trusted and workable international standard is developed for ballast water sampling and analysis, one that is based on a proven methodology for representative sampling and analysis of ballast water.   Full article


Methodology used by Chelsea Technologies’ FastBallast Sensor independently verified by third party benchmark testing

CTG today announced that independent benchmark testing on behalf of the Chinese government has identified the Single Turnover One Pulse (STOP) method used by the company’s FastBallast sensor as the most accurate methodology for portable ballast water sampling. Researchers from the Environmental Protection & Energy-saving Technique Research Centre of China Waterborne Transport Research Institute analysed the different methodologies used in commercial portable ballast water sampling systems, including the STOP-based statistical method, a multiple turnover PAM (Pulse Amplitude-Modulation) methodology, a portable staining method and flow cytometry, all compared against fluorescein-based laboratory standard staining methodology (FDA/CMFDA). The STOP method was identified to deliver the highest degree of accuracy and confidence in portable ballast water testing and analysis.

Chelsea Technologies Group secures ClassNK Certification for Sea Sentry - The Sea Sentry wash water monitoring system provides assurance that shipowners and operators are compliant with wash water discharge regulations

Chelsea Technologies, a world leader in the design and manufacture of sensors for the maritime sector, has today announced that its  Sea Sentry wash water monitoring system for ship exhaust gas cleaning systems has been certified by ClassNK. The certification provides assurance to shipowners and operators that all available measures have been taken to verify that Sea Sentry provides accurate and robust data to demonstrate compliance with IMO Annex VI wash water discharge regulations. It also underpins Chelsea Technologies’ commitment to achieving type approval for all of its systems.



The importance of testing standards in ballast water compliance

Since the entry into force of the Ballast Water Management Convention (BWMC) last year, coupled with increasing intensity shown by the United States Coast Guard (USCG) regarding enforcement and compliance testing, shipowners are facing an uphill battle to achieve compliance. In a recent report, the USCG noted a lack of familiarity among crews regarding the strategy and operation of Ballast Water Management Systems (BWMS), as well as confusion around maintenance practices and procedures. All of this creates a significant risk of non-compliance, even if the shipowner has installed a type-approved BWMS.
