Resolving Complex Autopilot and Steering Issues on the MONA SWAN

The Challenge

The MONA SWAN, operated by UNI-VESSELS APS, faced critical issues with its steering gear and autopilot control panel. The vessel was plagued by an 'Emergency - servo loop 07 and 08' error, causing stuck rudder positions, erratic rudder movements, and unreliable autopilot performance. Even after several attempts were made to fix the issues but were unsuccessful, leaving the vessel in a compromised state. Our team encountered several unexpected hurdles during this project. Multiple faults in the autopilot and steering systems demanded extensive troubleshooting and made it difficult to estimate repair times, directly impacting the vessel’s schedule and costs. Engineers often worked overtime both onboard and while travelling to keep operations moving. Delays in spare part deliveries added further pressure

The Solution

We were approached to resolve these persistent issues. Our expert service engineers attended the vessel and undertook a thorough inspection of the steering and autopilot systems. Replaced the potentiometers and amplifier board, as recommended during the previous service. Engineers then performed precise adjustments, configured the system and set up the system according to standard procedures. After completing the work, they thoroughly tested and verified the operation of the steering system and autopilot. As a result, they resolved the long-standing malfunction of the steering system, ensuring everything was functioning correctly.

The captain of MONA SWAN remarked, "Selene Marine's expertise was pivotal in resolving our steering system issues. Their engineers' dedication and precision brought our vessel back to optimal performance." 

The Results

After comprehensive testing, the steering system and autopilot on the MONA SWAN were restored to full operational status.

We have completed the service within 2 days, deploying 2 engineers. The delivery of spare parts took 15-20 days, and the actual repair was completed in 8-10 hours. The successful resolution of these issues ensured reliable and efficient vessel operations. The captain of MONA SWAN expressed satisfaction, highlighting the engineers' dedication and precision in bringing the vessel back to optimal performance.
