CM Technologies (CMT), specializing in advanced condition monitoring solutions, is calling on shipowners and managers to join collaborative trials designed to capture vital data on one of the shipping industry’s most costly problems: cylinder liner scuffing in two-stroke engines.

Scuffing, a form of sudden, severe wear, can result in catastrophic engine damage and vessel downtime. And while it’s a well-known issue, typically affecting large two-stroke diesel engines found on bulkers, tankers, and large container ships, the root causes are difficult to pin down. Operators, OEMs, and service providers have long struggled to predict or prevent the phenomena.

Germany-based CMT has developed a system that can alert operators to early onset cylinder damage and seeks trial partners for critical data gathering to validate the sensor’s predictive capabilities and to prevent engine damage.

CMT’s recently developed Scuffing Sensor system, a “stethoscope for cylinder liners,” uses high-frequency acoustic emission technology to detect the earliest signs of friction and wear from outside the cylinder.

Unlike other methods that rely on visual inspection or oil analysis performed weeks apart, this approach captures real-time acoustic data without interrupting engine operation. By identifying wear-related noise patterns, the system provides a potential early-warning signal before damage occurs.

Trial partners are invited to deploy the system onboard vessels equipped with two-stroke diesel engines. Ideally, these vessels will call at ports in Northern Europe, Germany, the Netherlands, Belgium or France, where CMT engineers can easily access them to install and retrieve data-logging equipment.

Shipowners or managers interested in participating in the scuffing detection trials are invited to contact CM Technologies at: info@CMTechnologies.de.
