Cargo Stowage: Stability, Segregation, Securing

Every loading plan answers three questions, in this order.

1. Stability

Will the ship remain stable at every stage of loading, discharge, and the voyage? Calculate GM, check against the stability booklet limits, and account for free surface effect in slack tanks.

2. Segregation

Are incompatible cargoes separated as required — IMDG classes, foodstuffs away from odorous or toxic cargo, reefer segregation? The dangerous goods manifest drives the stow, not convenience.

3. Securing

Can the cargo survive the worst expected motion of the voyage? Lash to the Cargo Securing Manual, not to habit. Check lashing certificates and calculate tipping and sliding for heavy units.

Golden rule

Dispute a stow before loading, not after. Once the hatch is closed, the problem belongs to the ship.
