How does it work - Free surfaces

Don’t let liquids rock the boat!

2018-02-22 | Onboard | No comments

Consider a large ship loaded with a liquid  – oil, for example (as is often the case). In a single large tank, the liquid tends to move around a great deal as the ship encounters waves. This is because the liquid has a lot of free surface to move around in. As you can imagine, this effect is rather harmful to the ship’s stability.

To solve the problem, ship builders reduce the free surface of the liquid by dividing the tank into smaller compartments. This film will show you how!:

To increase the stability of, say, an oil tanker, the free surface of the oil is reduced by compartmentalizing the cargo area. The smaller the compartments, the smaller the free surface – and the greater the stability of the tanker.
