Checking protections of the main air compressors

Greetings! I continue to write articles on checking the protection of various mechanisms on a ship and this time we will consider the compressors of the starting air of the main engine. Usually, they are of no interest to inspectors, but there are exceptions.

In this article, we will consider the main protections of the main air compressors that directly concern electricians. Let's take Japanese TANABE compressors as an example.

Boiler safety devices. A quick check for the surveyor

Greetings! In this article I recommend that you familiarize yourself with the main safety devices of auxiliary boiler on a ship that inspectors like to check. It does not matter which inspector came to the ship (PSC, flag, annual surveyor, etc.), usually the checks are not much different.

Surveyors mainly look at how critical protections work (selectively), i.e. those protections that stop the boiler (shutdown protection). They are not very concerned with auxiliary signals (alarms). But it is necessary to be prepared for everything, i.e. for the fact that the inspector can check the auxiliary alarms of the boiler.
