Follow Oliver Trainor into the bowels of a sea monster. Oliver is a seafarer and engineer on cargo ships. As a fan of myNoise, he kindly offered to take a recording device along on one of his voyages, and to record the noises that form a part of his daily life.
Machinery noises in a cargo ship can be deafening, but with some good hearing protection - or here on myNoise - they can be relaxing. This generator can be used as a powerful noise blocker, assuming you are open to the idea of working (or sleeping?) inside a cargo ship.
Oliver took the trouble to record each piece of machinery separately. Of course, we have the sound of thethat drives the and moves the ship through the water, but also smaller ones, like the . This one, coupled to a generator, produces the electricity available aboard.
A whining noise can be heard in the. It comes from a high-speed centrifuge that is used to remove impurities from the ship's fuel before it is supplied to the engine.
The crackling noise comes from the. Why would one need to use inert gas, in a tanker? Because oil tankers produce flammable vapors when loaded for a voyage. Even when empty of oil, there can still be harmful flammable gases in the hold. These vapors present a great risk of explosion, when mixed with the oxygen in the air. To prevent this, an inert gas - one that does not contain oxygen - is produced on board, and pumped into storage areas where flammable gases are present.
