Oxygen measurement in process lines is verified onboard.

Marine vessels equipped with Wärtsilä Moss inert gas generator systems rely on precise oxygen measurement to maintain safe atmospheres in cargo tanks and piping. An oxygen analyzer or gas detector is critical for ensuring that the inert gas produced meets safety requirements and keeps oxygen levels low to prevent combustion and explosions. Our team specializes in on‑board calibration, repair, and commissioning of these analyzers and detectors in key maritime regions including Spain, Gibraltar, Bulgaria, Turkey, Romania, Netherlands, France, Germany, and Italy.

The oxygen analyzer used with inert gas systems measures the percentage of oxygen in the gas to confirm that tanks are properly inerted and safe for cargo operations. Accurate readings are essential, especially during loading, discharge, purging, and ballasting operations. Calibration ensures that the analyzer makes correct measurements and meets marine safety expectations. According to marine inspection standards such as SIRE 2.0 and inert gas system inspection guidance, fixed oxygen analyzers should be calibrated within 24 hours before starting inert gas operations and maintained within the vessel’s planned maintenance system.

Our engineers can perform thorough on‑board calibration using traceable calibration gases, verify span and zero accuracy, and align indicators with manufacturer specifications. We also handle diagnostic repair, sensor replacement, and full commissioning after installation or overhaul. Services are available at major ports such as Algeciras, Valencia, Barcelona, Tarragona, Cartagena, Bilbao, Gijón, A Coruña, Vigo, Las Palmas, Santa Cruz de Tenerife, and international hubs like Lisbon, Rotterdam, Antwerp, Hamburg, Marseille, Genoa, Venice, Piraeus, Varna, and more.

Keep your inert gas oxygen analysis accurate and compliant with ship inspection and safety regulations with professional support wherever your vessel calls our ports.
