Cargo-specific Hold Guide
Select a cargo for hold preparation, voyage monitoring and post-discharge cleaning in three stages.
Scope, source date and conditions of use
See profile review date in Sources. General preparation and cleaning reference. Selecting a cargo does not authorise carriage, hold acceptance, enclosed-space entry or discharge. Use the exact declaration, vessel SMS, current schedule, manufacturer instructions and company-approved work plan.
PLAN THE CARGO TRANSITION
What did you discharge, what will you load?
Select two cargoes to open previous-cargo cleaning checks and next-cargo preparation requirements in one file.
SELECT THE CARGO • PLAN PREPARATION
Choose the cargo. Follow three stages.
Prepare the hold → monitor at sea → clean after discharge. Select your cargo, then open the stage you need.
38 cargo selections in 7 categories. Do not infer a method for an unlisted cargo by selecting a similar one.
Choose a cargo by category
Open a category, then choose the exact product. Do not substitute a similar profile for a different name or form.
