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.

Which Maritime Professions Will Be Replaced by Artificial Intelligence in the Next 20–50 Years? Will the Electro-Technical Officer Still Be Needed?

Artificial Intelligence (AI), automation, and robotics are rapidly transforming the maritime industry. What once sounded like science fiction — fully autonomous ships without crews — is now a reality in testing, particularly in countries like Norway and Japan. This raises an important question: which shipboard professions are at risk of becoming obsolete in the next few decades? And will there still be a place for the electro-technical officer (ETO) on future vessels?

Maritime Professions at Risk of Disappearing

1. Helmsman and Navigational Watch Officers

AI-powered navigation systems can already chart optimal routes, avoid collisions, and even dock with impressive precision. In the coming decades, the need for human intervention in navigation may be drastically reduced, especially for routine voyages or coastal operations.

Low voltage 220V. Incinerator does not work. Troubleshooting

Greetings! Today we have a problem with the waste oil incinerator. When starting the incinerator, the touch panel displays the error “Low voltage 220V”. The incinerator is not working. What kind of error is this and how to fix it, we will try to figure it out in the article.

Incinerator control panel

We turn to the instruction manual and see that the “Low voltage 220V” error is associated with a low voltage of 220V in the control circuit. 

The cargo crane does not slew. Troubleshooting

Greetings! Today we have a problem with the cargo crane, it won’t slew. In this case, there are no signals or alarms, the crane starts up, executes the commands “jib up, hook up” and “jib down, hook down,” but does not slew in any direction.

According to the instructions for the crane, you need to check the following circuit: Joystick - PLC - relay - Proportional Driver Unit - Proportional Valve.

Let's check the entire electrical circuit and figure out the reason for the improper operation of the cargo crane.

PLC failure. The cargo crane does not start. Troubleshooting

In previous articles we looked at various problems with cargo cranes, this time a PLC failure error occurred and cargo crane does not start.

What to do in such situation and how to restore the operation of the cargo crane will be discussed in this article.
