Sometimes the most frustrating situation at work is not the workload. It is when people around you do not see your expertise, underestimate your abilities, or look down on you before truly understanding what you can do. You may know the solution, have the experience, and even notice mistakes before others do. But reacting with…

Electrical drawings are one of the most important tools for an Electro-Technical Officer (ETO). In many ways, they are the language of electrical engineers on board ships. Without understanding drawings, it is difficult to fully understand how a system works or how to solve problems when faults happen. When we study a system, electrical diagrams…

Among all the 440V low insulation faults I’ve encountered, this case was quite unique. When the 440V insulation dropped all the way down to zero, I carried out the usual troubleshooting steps—tripping available breakers, shifting loads like pumps, and isolating circuits one by one—but I couldn’t locate the fault initially. Eventually, the issue was traced…

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…

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…

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…

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…

Searchlights commonly use Xenon lamps, which are also known as HID (High Intensity Discharge) lamps. When people want brighter car headlights, they often switch to this type of lamp. The construction consists of a quartz tube containing two electrodes, filled with xenon gas and metal salts (metal halides). When high voltage is applied between 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…

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,…
