Calibration and functional testing of EPCON electro pneumatic valve controller.

Electro pneumatic valve controllers are critical components in marine control systems, providing accurate regulation of valves used in temperature control, flow regulation, and process automation. Any drift in calibration or loss of control accuracy can result in unstable operation, reduced efficiency, or safety concerns.

This image shows an EPCON electro pneumatic valve controller by Controls Inc. undergoing calibration and functional testing. The service process includes verification of input signals, pressure output accuracy, manual and automatic mode operation, and response to control adjustments. Each function is checked to ensure the controller performs reliably under real onboard operating conditions.

Our calibration and health check services are designed to identify deviations early and restore proper performance before operational issues arise. Where required, fine adjustments and minor repairs are carried out to ensure the controller meets expected performance standards.

We support vessels during port calls and anchorage stays, providing efficient onboard service with minimal disruption to operations.

Portable calibration laboratory setup ready for onboard instrumentation service.

Modern vessels rely on a wide range of measuring and safety instruments, all of which must remain accurate to ensure safe operations and regulatory compliance. Bringing equipment ashore for calibration is not always practical, especially during tight port schedules or anchorage stays.

This image shows a portable calibration lab prepared onboard a tanker. Our technicians carry certified reference instruments, test equipment, and accessories in a dedicated transport case, allowing calibration and functional checks to be performed directly on board. This setup supports the servicing of portable gas detectors, temperature and pressure instruments, electrical signals, and other critical onboard equipment.

By working onboard, we reduce downtime, eliminate unnecessary logistics, and allow vessels to stay operational while required technical work is completed. All checks are carried out with practical operating conditions in mind, ensuring instruments perform reliably in real service, not just under laboratory conditions.

This approach is especially valuable in busy ports and during anchorage, where flexibility and efficiency are essential.

Calibration and bump test of a GMI PS200 portable gas detector using an automatic docking station.

Portable gas detectors are a vital part of crew safety, especially during enclosed space entry, maintenance work, and routine watchkeeping. To remain reliable, these instruments must be regularly bump tested and calibrated using controlled and repeatable methods.

This image shows a PS200 portable gas detector from GMI undergoing calibration in an automatic docking station. The docking system applies test gas at controlled concentrations, verifies sensor response, and confirms alarm activation for oxygen, combustible gas, carbon monoxide, and hydrogen sulfide. Once completed, the detector is ready for safe operational use.

Using docking stations helps standardise calibration procedures, reduce human error, and ensure detectors perform as expected every time they are issued to crew. It also supports inspection readiness by demonstrating proper maintenance of personal safety equipment.

Onboard calibration and technical service carried out during vessel anchorage in Spanish waters.

Not every service has to wait until the vessel is alongside. Many calibration and inspection tasks can be completed safely and efficiently while the ship remains at anchorage, saving valuable time and keeping schedules on track.

This image shows a tanker at anchorage during onboard service activities. Our technicians regularly carry out calibration, inspection, and functional testing of marine instrumentation directly onboard while vessels are waiting for berth availability, cargo operations, or clearance. This approach reduces delays and allows crews to address technical requirements proactively.

We support a wide range of onboard systems, including gas detection, bilge alarms, ODME systems, temperature and pressure instruments, and tank gauging equipment. All work is performed with practical onboard conditions in mind, focusing on safety, accuracy, and clear verification of results.

Anchorage service is particularly valuable in busy ports where berth time is limited and operational windows are tight. By working directly at anchorage, we help operators maintain compliance and readiness without disrupting voyage plans.
