112 pages. Available in print and on Witherby Connect.
The full tank-cleaning process from requirement to verification.
Tank cleaning depends on more than the previous and next cargo. TANK CLEANING PRACTICE brings together cleanliness standards, cargo and environmental factors, coatings, cleaning methods, recipe formation, safety, onboard preparation, testing and the MARPOL and IBC Code requirements.
Assess the operation
Define the cleanliness requirement and identify the cargo, tank and environmental factors that affect the cleaning task.
Develop the approach
Choose the cleaning method and turn the requirements into a practical plan and cleaning recipe.
Prepare the vessel
Align the crew, responsibilities, equipment and sequence before cleaning begins.
Verify the result
Use inspection, wall wash testing and analysis to determine whether the tanks are ready for the next cargo.
From cargo requirements to a clean tank.
Eighteen chapters cover the properties, decisions, methods and checks behind a complete tank cleaning operation. Each subject is treated as part of the same process, not as an isolated reference.
