Chelsea Technologies’ FastBallast ballast water compliance monitor has been selected by the Canadian government agency Fisheries and Oceans Canada to take part in a 4-month ballast water monitoring programme.

“Chelsea is working with regulators and port state authorities to develop an international standard for ballast water sampling and analysis, based on a proven methodology for representative sampling and analysis of ballast water,” said Chelsea Technologies managing director Dr Brian Phillips.

The programme is being managed by the Great Lakes Laboratory for Fisheries and Aquatic Science and will assess portable ballast water monitoring technology to provide an accurate, rapid assessment of ballast water to prove compliance with the Ballast Water Management Convention.

FastBallast is the only compliance monitor to use a statistical method to generate an estimate of cell density that is independent of an assumed level of fluorescence per cell.

The statistical analysis is based on the Poisson distribution theory which ensures a true analysis of the ballast water sample and is also used by the Great Lakes Laboratory in its methodology.

The statistical methodology provides a pass/fail response in under 10 minutes and is the only technology capable of operating in a flow-through mode, while providing a high degree of accuracy with a representative report on discharge compliance.

It was just over a year ago that Chelsea Technologies announced a similar programme with Saudi Aramco and the Swiss testing and certification organisation, SGS Group, which will use equipment supplied by aqua-tools of France to inspect and monitor treated ballast water in vessels arriving at ports in Saudi Arabia.

FastBallast’s unique capability uses the single-turnover method, rather than the PAM multiple-turnover method, which provides a much lower detection limit (< 1 cell per mL) as the 20 mL sample size avoids sampling problems at low cell densities.

It can determine the phytoplankton cell density of ballast water to IMO D2 and USCG discharge standards (10 to 50 µm range), with an equal degree of confidence as laboratory analysis.

Since August 2017 Saudi Arabia has been conducting ballast water monitoring on vessels and conducting spot checks to ensure compliance.

Sampling data was obtained from more than 500 vessels by Global Strategic Alliance using CTG’s FastBallast monitoring system.

A pass rate of 90% was reported for vessels using IMO D2 standard.
