Washing Water Analysis:

The ability to monitor tank cleaning operations “live” by analysis of washing water samples using the L&I Wave II UV / Vis spectrophotometer. Very simply, when the washing water effluent no longer contains significant traces of the previous cargo, tank cleaning can be stopped.

Key Benefits:

1. Optimisation of tank cleaning procedures
2. Reduction in confined space entry for crew members
3. Preservation of rest hours
4. Potential to reduce cleaning chemical consumption
5. Potential to reduce fuel consumption related to the boiler operation
6. Potential to reduce the environmental foot-print of the vessel in terms of CO2 emissions and discharge of detergents to sea
7. Elimination of the need for wall wash inspection

Chemical cargoes have different UV fingerprints, which allows operators to accurately determine when tank cleaning can be stopped.
