We successfully completed the full calibration and functional verification of the Riken Keiki RM‑590 Fixed Gas Sampling System onboard. The scope of work included a detailed inspection of the sampling line, operational checks of all pneumatic components, and precise adjustment of the detection channels to ensure accurate and dependable readings under all conditions.

Our team verified the correct operation of pumps, filters, and solenoid valves, confirming stable sampling flow throughout the system. Using certified calibration gases, we performed zero and span adjustments for the O₂, LEL, and H₂S detectors, restoring each channel to optimal measurement accuracy. A final simulation test validated the system’s response, confirming proper alarm activation, signal transmission, and overall functionality.

Another step forward in ensuring reliability, safety, and seamless operation at sea. During this maintenance period, our team carried out the scheduled service of the Transmitter Box for the W.B.T. Remote Sounding System, including detailed inspection and corrective work on the main panel. Every task was performed with precision and full adherence to the system’s technical requirements, ensuring that all components continue to operate with accuracy and stability.

Maintaining remote sounding systems in optimal condition is essential for delivering real‑time, trustworthy tank level information to the bridge. By thoroughly checking, cleaning, and verifying the transmitter circuitry and panel connections, we ensured that the system remains responsive and dependable under all operating conditions. This level of reliability is critical for safe cargo handling, ballast operations, and overall situational awareness onboard.

The inspection and calibration of the Oil Mist Detector Graviner MK6 was carried out onboard the vessel, where our team performed a complete functional check of the entire system. Each sensor was tested individually to verify correct response, stability, and sensitivity according to the manufacturer’s specifications. The main control panel was also inspected thoroughly, including its internal electronics, alarm circuits, and configuration parameters. All wiring routes and terminations were checked to ensure proper continuity and signal integrity, confirming that the installation remained in good condition and free from faults.

Following the inspection, a full calibration procedure was performed on every sensing head to ensure accurate mist‑level detection across all channels. Alarm thresholds, timing sequences, and safety interlocks were verified through controlled tests, confirming that the system responded exactly as intended. The panel’s settings were reviewed to ensure no unauthorized adjustments or modifications had been made, and all parameters were aligned with Graviner MK6 standards.

The Replacement of the Diesel Generator Safety Panel project involved upgrading the vessel’s generator‑protection infrastructure with a completely new and purpose‑built panel. The outdated unit was removed in full, and a modern safety panel—designed for clearer status indication by Alpha Automation, improved fault detection, and enhanced operational reliability—was installed in its place. All field wiring and protection circuits were reviewed during the process, ensuring that every connection met current standards and interfaced correctly with the new system.

Once installation was complete, the panel underwent a full sequence of operational checks, including verification of alarms, shutdown protections, and monitoring functions under simulated fault conditions. The new panel demonstrated stable and accurate performance, giving the crew a far more dependable and user‑friendly safety interface for the diesel generator. This upgrade not only improved day‑to‑day operation but also strengthened the vessel’s overall safety readiness.

The Replacement of the Fire Alarm System project involved the complete removal of the vessel’s old fire‑detection panel and the installation of a brand‑new, modern, and fully compliant system. The new panel was engineered to provide clearer indications, faster response times, and improved reliability across all monitored zones. All wiring, terminations, and field connections were checked, renewed where necessary, and integrated seamlessly with the new unit to ensure stable communication with detectors, alarms, and auxiliary safety circuits.

After installation, the system underwent full functional testing, including zone checks, alarm verification, fault simulations, and confirmation of both audible and visual indications. The new panel performed flawlessly, offering the crew a far more intuitive and dependable interface for fire detection and emergency response. The upgrade significantly enhanced onboard safety and brought the vessel’s fire‑alarm infrastructure up to modern standards.

The Fixed Gas Sampling System inspection and calibration project began with a full functional check of all installed gas sensors, including HC, H₂S, and O₂. Each sensor was tested across its operating range and calibrated to ensure accurate and stable readings. In parallel, we serviced the system’s suction pumps by installing new repair kits, restoring proper vacuum performance and sampling flow. The sampling tubes were also cleaned thoroughly to remove small amounts of moisture that had accumulated inside, ensuring unobstructed and reliable gas transfer to the sensors.

The Installation of a New Panel for a Single‑Channel Gas Monitor project involved the complete replacement of the vessel’s existing monitoring setup with a newly constructed, purpose‑built panel. Our team designed and installed the new panel to interface seamlessly with the ship’s single‑channel gas detection system, ensuring accurate real‑time monitoring of the designated gas line. All wiring, terminations, and safety interlocks were installed according to marine standards, and the panel was configured to provide clear visual indications, alarms, and operational feedback to the crew.

After installation, the system underwent full functional testing to verify correct sensor readings, alarm activation, and stable communication with the gas monitor. The new panel performed flawlessly, delivering reliable detection capability and significantly improving the clarity and usability of the monitoring interface. The result is a modern, robust, and fully operational gas‑monitoring panel that enhances onboard safety and ensures compliance with vessel requirements.

The inspection and calibration of the Vapour Emission Control System (VECS) panel were carried out with full attention to both safety and measurement accuracy. Our team tested and calibrated the oxygen sensor, vapour pressure indicator, and alarm module to ensure that each component responded correctly across its operating range. In parallel, all electrical and pneumatic wiring was inspected, verified, and corrected where necessary to eliminate faults, signal drops, or inconsistencies. This comprehensive approach ensured that every part of the VECS panel operated within the required specifications.

Following the calibration process, the entire system was tested under controlled conditions to confirm stable and reliable performance. The readings from all instruments were validated as accurate, and the alarm module responded precisely to threshold conditions. With all components functioning correctly and the wiring fully verified, the VECS panel now operates smoothly, providing trustworthy indications and ensuring proper vapour‑emission monitoring during cargo operations.
