The marine industry requires routine marine water testing to ensure safe water quality, regulatory compliance, and environmental protection.
The Marine Labour Convention requires that seafarers have access to clean potable water for drinking, cooking, and other purposes. In recent years, IMO regulations have become stricter, requiring that the water on board vessels are free of harmful marine organisms and contaminants and do not cause any damage when discharged to the sea.
Viswa offers comprehensive marine water testing services, including potable water testing, ballast water analysis, bilge water analysis, and gray water testing and analysis, along with onboard machinery assessments to ensure treatments meet statutory approval criteria while protecting crew health and the marine environment.
