Main Engine Protections. Quick Check for Inspectors

Greetings! In this article, I recommend that you familiarize yourself with the main protections of the main engine on a vessel, which are most often checked by inspectors. The main engine and its auxiliary systems have a lot of protections, so only the main ones will be described, which are demonstrated when passing a particular check.

The main engine and auxiliary engines differ mainly in their purpose. But in terms of protection, they have much in common. In the article "Diesel Generator Protections. A Quick Check for the Inspector" oil mist detectors (OMD - Oil Mist Detector) were mentioned, which can be installed on diesel engines with a capacity of 500 - 1000 kW, so on the main engines, as a rule, they are.

Diesel Generator Protections. A Quick Check for an Inspector

Greetings! In this article, I recommend that you familiarize yourself with the main protections of diesel generators on a ship, which inspectors like to check. There are many protections on ship diesel generators and one article is not enough to consider them all, so only the main protections will be described, which are most often demonstrated when passing a particular check.

Using the example of the Daihatsu 6DE-18 diesel engine and the Taiyo FE 647A-8 brushless synchronous generator, we will consider the protection of marine diesel generators and how to test them. Other most common diesel engines (Himsen, Yanmar, MAN B&W) found in the merchant marine fleet will also be partially covered.
