Ship's Potable Water & Ballast Water Testing
Independent ship potable-water and ballast-water sampling with traceable handling and laboratory coordination.
Overview
Practical attendance with traceable records
We arrange representative onboard sampling, correct bottles and preservation, sample identification, documented chain of custody and transport to an appropriate laboratory. The agreed scope may cover vessel drinking-water quality, microbiological risk or ballast-water parameters required for a particular port, flag or operational purpose.
Testing is arranged against the standard agreed with the client, vessel, flag state or port authority. Where accredited analysis is required, samples are submitted to a suitable accredited laboratory; Headway Marine does not represent itself as the laboratory.
