How to strrrrretch a ship
http://rusbankinfo.ru/credits.html During Stena Line’s history, we’ve extended several ferries to increase their capacity. The last time we did it was in 2007 when Britannica and Hollandica, on the Hoek van Holland – Harwich route, were extended by an astonishing 50 metres. (When we cut them in half.) We then renamed them Germanica and Scandinavica and…
What’s the difference between a propeller & an aircraft wing?
https://rusbank.net Less than you might think, actually. The propeller, of course, is what moves a ship forward and backward (or “astern”) in the water. And it builds on the same principle as a wing on an aircraft. Aircraft wings are curved in order to create a difference i...
Don’t let liquids rock the boat!
срочный займ онлайн на карту 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 surfa...
Balancing with ballast!
Ever heard the word ballast? It comes from the old Nordic word “barlast” which means without (“bar”) cargo (“last”). And there’s a reason for that… When a ship is fully loaded (say, a ferry carrying hundreds of cars and trucks), the weight of the load submerges the hull in the water. This is good because,…
How the heck do you weigh a ship?
If you caught the first episode of our series, where we talked about buoyancy, you may remember that the weight of the water that a ship displaces is equal to the weight of the ship itself. This is known as the Archimedes principle. But how do you establish the weight of that water? Ship builders…
What the king didn’t know …
When Swedish king, Gustav II Adolf ordered the royal warship Wasa, he clearly knew nothing about the importance of center of gravity. He ordered an extra cannon deck built – and the Wasa capsized instantly on her maiden voyage in 1628. Not exactly a proud moment in history of Swedish shipbuilding … The center of…
The strange case of the vanishing water …
No crane in the world is strong enough to lift a 20,000-tonne vessel up in the air. Nevertheless, every once in a while, a ship does need to have its underwater hull painted, maintained and repaired. And you can’t really do that while the ship is in the water. The solution? ...
It’s not just a fancy nose job: we’re saving the planet!
You’ve probably seen a bulb-like shape protruding from the bow of a ship. Our ferries all have one. But what is it and what’s it doing there? Well, the bulb is a clever invention that helps to decrease a ships resistance as it travels through the water. The result: more speed, less fue...
