How to sell Starlink? Experience selling a Starlink REV4 through Vinted

Selling a Starlink is entirely possible, especially if you properly prepare the equipment and choose a convenient location. Here's how it might work in practice, using the example of selling a Starlink REV4 kit from Poland to a buyer in Croatia through the Vinted platform.

How I Sold My Starlink REV4

⭐️ Here's a free month of Starlink! Starlink's high-speed internet is perfect for streaming, video calls, and gaming, even in the most remote corners of the world.

I decided to sell my Starlink REV4 kit after I stopped using it. New equipment is significantly more expensive, so even a used one is of interest, especially in countries where delivery or availability is limited.

The Most Common Failure in Marine Equipment: Loose Electrical Connections

When we talk about ship machinery — engines, automation, refrigeration plants, pumps, generators—the most frequent cause of failures is not a broken mechanical part.

In real life, the number one cause of faults on ships is electrical issues, and especially one simple problem:

Electro-Technical Officer (ETO) - Job description. What is this? Example of a marine electrical engineer job description

In the maritime industry, ETO stands for Electro-Technical Officer. This is a specialized crew member responsible for maintaining and managing all electrical, electronic, and automation systems on board a vessel. An ETO job description outlines the duties, skills, and qualifications required for this critical role.

Who Is an Electro-Technical Officer?

An Electro-Technical Officer (ETO) is a shipboard engineer who ensures that all electrical and electronic equipment operates safely and efficiently. Unlike traditional marine engineers who focus on mechanical systems, the ETO deals primarily with electrical power, control systems, and advanced technology.

Bridge & GMDSS Radio Equipment. Overview and Troubleshooting Guide

Modern ships rely on Bridge navigation electronics and the GMDSS (Global Maritime Distress and Safety System) to ensure safe navigation and emergency communication anywhere in the world. Failure of this equipment can stop a vessel from sailing, cause Port State Control detention, or create real safety risks.

This article explains the main bridge, GMDSS equipment and provides practical troubleshooting methods used onboard.

How to Choose a Fluke Insulation Tester for Marine Work

Choosing a Fluke insulation tester (megohmmeter or megger) for marine work is not just about price — it’s about test voltage, diagnostic capability, reliability, and safety in harsh environments. Below is the article with real-world models and prices in USD.

How to Choose a Fluke Insulation Tester for Marine Work

Working on a ship means dealing with high humidity and salt exposure, critical electrical systems (generators, motors, switchboards), strict safety standards. That’s why your insulation tester must be reliable, accurate, and powerful enough for marine systems.

What Is a Loop Calibrator? How to Choose the Right One

A loop calibrator is one of the most essential tools in industrial instrumentation. Whether you work with PLCs, sensors, or process control systems, you will eventually deal with the standard 4–20 mA signal—and that’s exactly where this device becomes indispensable.

What Is a Loop Calibrator

A loop calibrator is a device used to measure, generate, and simulate 4–20 mA current signals, which are widely used in industrial automation.

In practical terms, it allows you to:

• test sensors (pressure, temperature, level),
• simulate signals during commissioning,
• calibrate PLC or controller inputs,
• troubleshoot signal loops.

The 4–20 mA standard is popular because it is resistant to noise and works reliably over long distances. A loop calibrator acts as a reference tool for verifying that everything in the loop is working correctly.

What is EGR and SCR on a ship? Troubleshooting and Fault Finding

Modern marine diesel engines operate under strict environmental regulations established by the International Maritime Organization (IMO), particularly Tier II and Tier III NOx limits. To comply with these standards, ship engines are equipped with exhaust gas emission control systems.

The two main technologies used onboard are:

• EGR (Exhaust Gas Recirculation)
• SCR (Selective Catalytic Reduction)

Both systems are designed to reduce nitrogen oxides (NOx), but they work in fundamentally different ways.

As an example, the article considers the MITSUI-MAN B&W 6S50ME-C9.5-EGRBP main engine with an EGR system and auxiliary Daihatsu 6DE-18 Tier III 630kW engines with an SCR system.

MAN ME Electronic Main Engine. Troubleshooting

Greetings! In this article, I introduce the MAN ME electronic main engine, the general concept of MAN ME engines, and examine its individual components — FIVA, ELVA, ELFI, Alfa Lubricator, and Tacho Pickup — as key systems for troubleshooting. As an example, the article examines the MITSUI-MAN B&W 6S50ME-C9.5-EGRBP main engine with an EGR system.

Modern two-stroke, low-speed engines from the ME series by MAN Energy Solutions are fully electronically controlled engines. Unlike mechanical systems, fuel injection, exhaust valves, and cylinder lubrication are controlled by electronic control units via hydraulic actuators.

This article summarizes key information on the main engine systems and troubleshooting algorithms.

Techcross BWTS Troubleshooting. Complete Operating Logic and TRO Troubleshooting Guide

Greetings! In this article, we'll discuss the Techcross BWTS (ECS) ballast system, its operating logic, and troubleshooting instructions from the Korean manufacturer.

The Electro-Cleen System (ECS) by Techcross is an electrochlorination-type Ballast Water Treatment System (BWTS). It disinfects ballast water during uptake by generating sodium hypochlorite (NaOCl) from seawater and neutralizes residual oxidants during discharge to comply with IMO D-2 regulations.
