Introduction The Sound Reception System (SRS), commonly known among seafarers as “Elephant Ears,” is installed on totally enclosed bridges in accordance with SOLAS and COLREGs requirements. Since modern bridge designs are enclosed to improve safety and working conditions, natural external sounds such as whistles, fog signals, and other vessels’ warnings cannot be heard directly. The…

Vapour Phase Corrosion Inhibitors (VpCI or VCI) are widely used inside electrical cabinets and panels during storage and transportation. Their primary purpose is to prevent corrosion, especially before marine delivery or long-term storage. VCI works by releasing vapour-phase particles that form a microscopic protective layer on metal surfaces. This layer isolates the metal from oxygen…

On normal vessels, we usually see Low Sea Chest and High Sea Chest arrangements.However, on the ice-classed vessel I am currently working on, the configuration is different.Instead of a high sea chest, the system is arranged with a Low Sea Chest and an Ice Sea Chest. This post explains how seawater cooling is managed safely…

To be honest, AMS/IAS is not difficult for end-user handling and troubleshooting.Still, as a junior ETO, I used to hesitate and overthink everything during the early days of my career. On board, this feeling was made worse by comments like: “Don’t touch it.”“That system is sensitive.” When responsibility came, confidence dropped.Even simple tasks felt risky,…

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,…
