  • In the world of marine electrical engineering, it is easy to rely solely on past experience when solving problems. After all, experience is valuable. It gives us quick recall of solutions that worked before. But there is a catch: ships change, systems change, and what worked on one vessel may not apply to another. As…

  • After the previous section in this category, I would like to proceed to examine how the K-Chief system and the cargo pump starter are related. As an ETO, it is essential to know which diagrams or instruction manuals you need to refer to in order to understand the system and effectively troubleshoot any issues. Figures…

  • In our shipping career, we often talk about being “qualified” or “certified,” but that alone is not enough to be respected on board — especially for an ETO. Unlike other ranks, an ETO usually works alone. That means your value is judged purely by your skill, attitude, and how well you carry yourself in a…

  • In the previous section, I introduced the basic architecture of the K-Chief 600 cargo monitoring system, including the functions of each module and how they are connected. By understanding this structure, most problems onboard can be handled and troubleshooted without much difficulty. Even if the issue cannot be solved immediately, you’ll be able to identify…

  • Previously, I briefly explained how the K-Chief 600 AMS system handles digital and analog input/output modules onboard, based on my own experience. I also shared how these modules interface with systems like Engine AMS, Tank Gauging, and Valve Remote Control, and mentioned some real-life troubleshooting cases I’ve encountered. Now, before diving deeper into how these…

  • K-Chief 600 – Basic Understanding of Input/Output Modules (Based on Real Experience) Before explaining how input/output modules (I/O) are connected in the K-Chief 600 system, both in hazardous and non-hazardous areas, I’d like to share some background based on my hands-on experience. I/O modules are foundational to instrumentation systems. So, before connecting or troubleshooting them,…

  • For experienced ETOs and marine engineers, what I am sharing here may seem simple. But for junior ETOs and engineers who are just starting, these things can be hard to understand. I want to help those new to the job by sharing what I have learned. From my real work experience as an ETO and…

  • In the introduction of ME Engine Control System, I wrote about the ME Engine Control System, under the MPC cards section, I briefly mentioned the LDCL system as part of the Cooling Water Control Unit (CWCU) MPC card. Recently, while troubleshooting to restart the LDCL system on the ship that has been stopped for a…
