Boilers generate steam and have been used since the era of steamships, and are used to date. They utilise the heat index generated from engines and machinery onboard to produce steam vapour by boiling water at very high temperatures and pressures, and this steam is used for various utilities on the vessel that use heating systems.

For tanker vessels carrying various forms of heavy fuel and bunker fuels, complex heating systems supply constant heat to the cargo so that they remain at the desired...

An eductor is a simple version of a pump used to move a liquid form of a fluid out of a certain place.

However, unlike more complex versions of pumps, they do not have any mechanised components or moving parts that create an external force to transport a certain quantity of water. Instead, they rely on the simple theory of Bernoulli’s principle and a specific case of this, the Venturi effect.

What is Bernoulli’s principle?

As we know from the classical theory of fluid mechanics, Bernoulli’s...

The available sea depth, the distance from the mean water level to the seafloor, is often an essential parameter for consideration. For navigation of vessels (refer to the article on underwater keel clearance), fishing, oil explorations, rigging, research, and various purposes, estimating the depth of the ocean bottom is indispensable.

An echo sounder is a system that helps understand what is underneath and has been used by most seagoing ships for a long time. This system, which is one of the...

I still remember the day when I joined my maiden vessel more than a decade ago. A Supramax bulk carrier with the least automation and the most troubles. I was welcomed by a lot of judgemental yet uncaring eyes.

A new Cadet is on board! To add some spice to it, he’s a first-timer and presumably stupid; An old and tough Soviet Chief Officer who’s pissed because he couldn’t sign off in the last port.

Rain poured down the sky, and the day couldn’t get gloomier beyond imagination. I was shown my...
