The right tank cleaning between cargoes protects against contamination and off-spec claims. The Tank Cleaning Agent reads the cargo nomination, compares the previous and next cargo with the tank cleaning guides, and drafts the cleaning instructions for the Master. Watch the interactive guide above for a click-by-click walkthrough.
