Petrik Naval provides onboard calibration of ODME HART flowmeters at the ports of Cartagena and Huelva.

The ODME flow meter is a critical component of the ship’s oil discharge monitoring and control system. Accurate flow measurement is essential not only for operational reliability, but also for meeting environmental and regulatory expectations during inspections and vetting.

Over time, differential pressure transmitters and orifice plates can drift due to vibration, temperature changes, and normal wear in engine room conditions. When calibration is overdue or performance is unstable, vessels face increased risk during Port State Control inspections, audits, and SIRE 2.0 reviews.

Our onboard service is designed to remove that risk. We provide professional calibration, troubleshooting, repair, and commissioning of ODME flow meters directly on board, minimizing downtime and avoiding unnecessary equipment replacement. Functional testing, signal verification, and documentation are completed during the visit to support compliance and vessel records.

With service coverage across major European and Mediterranean ports, our technicians can attend vessels during normal port stays, planned maintenance, or urgent situations. Whether the system requires routine annual calibration or corrective intervention after an alarm or inspection finding, we focus on restoring confidence in the ODME system quickly and efficiently.

Keeping ODME equipment properly calibrated is not just a regulatory obligation. It is a practical step toward smoother inspections, cleaner operations, and peace of mind for the crew and technical management.
