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.

The main engine does not start. Troubleshooting

Greetings! Today we have a problem with starting the main engine; the engine cannot be started with air by the telegraph command “Forward” and setting a certain speed (the telegraph and the speed controller are not one common device here).

In the article we will find out what the problem is and what you should pay attention to during routine maintenance of the main engine control unit.

Unmanned Machinery Spaces (UMS) Ships — Control and Alarm Requirements

The number of UMS ships has increased rapidly over the past few years. Control systems are much more reliable now than they were when first applied to ships. Educating the crew to understand control functions is now undertaken by most shipowners. More ships will, in future, be fitted with remote-control systems as a means of reducing crews.

Nowadays, however, far more UMS ships are in operation. Crews have grown familiar with the systems and training is more prolific. In the immediate future more owners will adopt UMS, not only as a means of cutting crew to a minimum and thus cut operational costs, but also for reasons of safety.

Control Systems. General Requirements

Automated machinery provided with automatic or remote control system, as well as, to the necessary extent, with monitoring systems, is in addition to be provided with means of local control.

In each case of failure in automatic or remote control systems, the possibility of local control is to be maintained.

Where machinery or installation is remotely controlled, it should be possible for the operator to check, with sufficient reliance, from his control station whether his command has been carried out by remote control system.
