German manager completes fleet-wide rollout of 300 CMT fuel testing kits

Glueckstadt, Germany-headquartered testing and monitoring solutions provider CM Technologies GmbH (CMT) reports that an undisclosed German ship management company has now rolled out CMT’s integrated onboard fuel/oil testing and analysis kits on its fleet of 300 containerships and bulk carriers.

Implemented progressively over the past decade, the fleet-wide rollout has established a common testing platform enabling consistent fuel and lubricating oil analysis across its fleet regardless of vessel type, trade route or operating profile.

CMT claims that the rollout represents a significant shift in the way ship managers and owners carry out onboard engine condition monitoring across large fleets.

“Rather than being treated solely as a vessel-level engineering function, fuel and oil analysis is becoming part of a broader operational control framework that supports fleet-wide decision-making, maintenance planning and risk management,” said CMT managing director Uwe Krüger. “Shipping companies are looking for solutions that provide immediate results onboard. They want monitoring consistency across their fleets.”

According to CMT the trend to standardized diesel engine performance monitoring followed the increased use of very low sulfur fuel oils (VLSFO) and other blended fuels after the entry into force of the IMO 2020 rules.

“This created new challenges for ship operators in terms of fuel stability, compatibility and contamination, which are becoming more frequent,” said Krüger.

Traditionally, operators have relied on shore-based laboratories to analyze fuel and oil samples. But while laboratory analysis remains an important part of machinery condition monitoring, the time required to obtain results limits the ability to respond effectively to developing issues, notes CMY.

“More and more shipping companies are equipping their vessels with our onboard fuel and lube test cabinets to make day-to-day fuel and lube analysis easier for crews,” Krüger said. “Regular testing is now the norm, routinely testing for water content, cat fines, viscosity, density, iron wear, and lubricating oil conditions.”

Water contamination, if undetected, promotes corrosion in engine components. Cat fines (catalytic particles of aluminium and silicon from the refining process) can pass through fuel treatment systems and cause rapid wear in pumps, injectors and cylinder liners. Viscosity and density checks at delivery give operators independent verification of bunker quality rather than reliance on supplier paperwork. And iron content analysis in cylinder drain oil tracks wear rates over time, flagging deterioration before it becomes a serious problem.

“Testing is such an important consideration it is now being built into daily operations onboard rather than carried out periodically or outsourced. A key benefit of the standardised approach is the ability to compare results directly between vessels,” said Krüger. “Because measurements are generated using the same equipment and procedures, technical teams can benchmark performance across sister ships, identify abnormal trends and investigate any deviations. This has transformed onboard testing into a fleet-wide intelligence tool.”

More recently, the shipmanager has upgraded its testing program with the replacement of traditional wet chemical iron test kits with CMT’s ferrous wear measurement device. The change has reduced dependence on reagents while improving repeatability and consistency in wear monitoring.

“Earlier identification of abnormal wear gives crews and technical managers more time to investigate and address problems before they develop into catastrophic engine failure and costly disruption. A single testing platform also cuts procurement complexity and ensures consistent training and data interpretation across the fleet,” Kruger noted.
