Ship stability

Home › Ship stability

Calculating ship stability is a fundamental aspect of ship architecture, ensuring that vessels can safely endure various conditions at sea. Stability involves assessing the balance and buoyancy of a vessel, taking into account factors such as weight distribution and environmental forces. Accurate ship stability calculations are critical for maintaining safety, compliance with maritime regulations, and optimal performance. The advanced tools and methodologies we developed at SARC are ideal for performing these calculations efficiently and effectively.

What does ship stability involve?

Ship stability describes the ability of a vessel to return to an upright position after it has been heeled by external forces. These are the main aspects:

Centre of gravity
Determining the vertical centre of gravity from the lightship weight and the loading condition.
Metacentric height
Calculating GM, a key measure of initial stability.
Righting lever curve
Calculating the GZ curve to assess stability at larger angles of heel.
Stability criteria
Checking the results against the applicable intact stability criteria.
Inclining experiment
Verifying the lightship weight and centre of gravity, supported by our measuring instruments.
Damage stability
Assessing stability after flooding with our damage stability calculations.

Frequently asked questions about ship stability

What is ship stability?

Ship stability is the ability of a vessel to return to an upright position after being heeled by forces such as wind, waves or shifting cargo.

What is the difference between intact and damage stability?

Intact stability concerns an undamaged vessel. Damage stability looks at a vessel with one or more flooded compartments. Read more about damage stability calculations.

Can I check stability on board?

Yes. With our loading software LOCOPIAS, the crew checks stability for every loading condition on board.

Can SARC carry out stability calculations for me?

Yes. Our engineers can carry out the calculations, including stability booklets. See our services.
