Key stability principles for ship stability during breakbulk cargo operations

A vessel can be stable in its final loaded condition and still develop a list halfway through loading. One heavy unit stowed high or off the centreline, or a lift sequence nobody checked at the intermediate stages, is enough. When someone then proposes extra ballast to carry on, the real problem usually sits in the plan or the data. This micro-learning by Proost & Partners and Loxygen shows how to catch it early.

You learn why high-stowed cargo raises the vertical centre of gravity and how off-centre weight creates a list. You apply a pre-loading checklist: verified cargo data, low stowage near the centreline, a defined lift sequence, stability checks at intermediate stages, an agreed ballast plan and clear stop-work triggers. You recognise the red flags, from missing data to "it worked last time", and follow a clear escalation route when conditions change, with the master or stability officer holding final authority.
