Select a cargo for hold preparation, post-discharge cleaning, previous and following cargo checks and chemical document links.

Scope, source date and conditions of use

Source review: 17 October 2026 · 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

One file before loading and after discharge.

Each cargo has two main sections: hold preparation and post-discharge cleaning. Add the previous and following cargo to bring their relevant checks into the same file.

First edition: 14 cargo profiles. Do not infer a method for an unlisted cargo by selecting a similar one.
