Chemical tank cleaning is a rigorous process that involves many ESG risks. Learn how Milbros UV Graphs is improving compliance, safety, and turnaround time.
Chemical and oil shipping companies are familiar with the traditional nuances of chemical tank cleaning, often involving long hours, unnecessary costs, and potential environmental safety risks.
Milbros, a Veson Nautical solution known for its extensive database of liquid bulk products, is paving the way for a safer, more efficient, and sustainable approach to chemical tank cleaning through UV graphs.
This feature is compatible with a spectrophotometer – a machine onboard ships that detects the transmittance of UV rays from a wash water sample. Cargo handling used to rely on wall wash analysis, which required crew members to enter confined spaces to sample various sections of the tank, exposing them to harmful chemicals that could result in potential incidents.
The wash water analysis allows commercial operators and crew to perform inspections remotely, preventing them from having to enter the tanks altogether. This technology is becoming more popular with many major shipping companies for its ability to measure tank cleanliness up to the required level, helping crew members avoid overcleaning, leading to increased safety, faster turnaround time, and reduced regulatory costs.
With Milbros UV Graphs, companies can fill out the data generated from the spectrophotometer to populate a graph that indicates whether the solution is compliant with 100 parts per million (PPM). If the graph falls below, then the tank is clean.
