Periodic / Preventive Measurements and Diagnostics of Engine Operation

  • Measurements of 2 – stroke and 4 – stroke engines.
  • Purchase of the measuring system and equipment by the shipowner
  • Training crews in the use of measuring equipment in order to perform measurements on their own.
  • First measurement always performed with the participation of our qualified measurement specialist.
  • A special pick-up sensor for RPM value collection is installed in the flywheel cover. Directly under the pick-ups a small hole in the flywheel is drilled (6x6mm) by our qualified measurement specialist.
  • All measuring points on the engine are marked by our qualified measurement specialist.
  • Speed of collecting the measurements depends on the skill of the crew.
  • Combustion measurements (if the indicator cock is available).
  • Vibration measurements in different positions (cylinder head inlet and exhaust valves, fuel pumps, injectors (2 – stroke engine), cylinder walls, camshaft bearing and main bearings).
  • Ultrasonic measurements in different positions for detection of gases leakage (cylinder head inlet and exhaust valves) and fuel leakage (Fuel pumps).
  • Professional analysis of the results, precise indication of the place and type of the problem.
  • A feedback file containing recommendations to improve engine performance is prepared by a qualified analyst and sent.
  • Recommendations are executed by the ship crew
  • Control measurement to check whether the engine operation has improved after applied recomendations
  • Reduces the costs of man-hours and the need to send our qualified measurement specialist (except first measurement).
  • Periodic engine measurements allow for continous monitoring of its parameters and performance

We offer the purchase and training in the use of our measuring equipment of reciprocating machines for crews all over the world. Our instruments and training are suitable for measuring 2 – stroke and 4 - stroke engines. A special pick-up sensor for RPM value collection is permanently instaled in the flywheel cover. Directly under the pick-up a small hole in the flywheel is drilled (6x6mm) by our qualified measurement specialist. All measuring points on the engine are marked. Installation of this type of measuring system on the engine takes up to 30 – 45 minutes.

The crew is trained that during the measurement the engine should be loaded with at least 50% (but the more the better) and how to measure the indicated pressure on each cylinder. Single measurement may take up to 10 minutes(depends on the skill of the crew). The crew is also trained in how to use the accelerometer and ultrasonic sensor and collecting vibration and ultrasonic measurements. Filling up the measuring card with the essential data from the engine is also a part of the crews training.

Our qualified measurement specialist will carefully explain every step of the measurement prosses, how to store the vibration data and how to send it to our qualified professional analyst for further analysis. The crew is also explained what the feedback files are.

All necessary manuals, maintenance records, sea trials reports, oil analysis, the measurement card, vibration and ultrasonic measurements are sent to a qualified professional analyst for further analysis.

An instruction that describes the whole process of taking the measurements is handed over to the crew by us.

The offered type of measurement and diagnosis is very effective and allows to accurately determine the place and type of the problem in the engine. Crew taking the measurements reduces the costs of man-hours and the need to send our qualified measurement specialist. Periodic engine measurements allows for continuous monitoring of its parameters and performance.
