OEM approved calibration and testing of marine fuel oil viscosimeter system.

Marine fuel oil viscosimeters are essential for maintaining correct fuel viscosity at engine inlet, directly impacting combustion efficiency, engine protection, and emissions control. Reliable operation of these systems is required under International Maritime Organization regulations and is routinely checked during annual surveys and Port State Control inspections.

This image shows a VIS 200 viscosimeter manufactured by Marsen undergoing calibration, repair, and health check. The service includes verification of viscosity measurement accuracy, temperature sensing, control valve operation, motor drive performance, and system response under simulated operating conditions.

As an OEM approved service provider, we perform maintenance and repairs using approved procedures and components. Each system is tested to confirm compliance with IMO requirements and prepared for annual survey and certification, giving shipowners confidence in both operational reliability and regulatory acceptance.

Our technicians support vessels during port stays and anchorage, delivering efficient onboard or workshop-based service with minimal disruption to operations.
