Our expert team offers full diagnostic support, UV sensor calibration and filter cleaning. We provide UK and international coverage, with both pre-planned and reactive support, travelling to vessel docking locations to minimise any disruption and downtime. Ballast Water Treatment Systems ensure that harmful aquatic organisms and pathogens aren’t transported across oceans. Like all systems, they require regular expert care to remain effective and compliant with IMO (International Maritime Organisation) regulations. Without regular servicing, systems can underperform, fail inspections, or cause expensive delays and environmental risks which is why Marlin recommends annual system services.
