Kongsberg MaritimeSoftware

Baseline• Software package to log, store, evaluate and

present data from the NK-200 MIP calculator

• Includes 9 important Model Curves (reference curves) for comparing the current engine parameters with optimal values

• Model curves are normally generated during sea trial by doing reference measurements on the engine at 4 different loads (60 to 110% MCR)

• All input data corrected to match ISO standards

• Baseline software developed in technical co-operation with the Norwegian Technical University and Det Norske Veritas

• Integration with Kongsberg C20 automation system

Future Engine Performance system from Kongsberg

/ 44 / 5-Jun-08

Kongsberg MaritimeShaft torque meter

Kongsberg now delivers an optical non-contact shaft torque meter to measure engine power and torsional vibration levels

This system is very easy to install - both on new and existing vessels

This system has no critical sensor installations on the shaft (i.e. no strain gauges)

Kongsberg is working on a full integration of this system into K-Chief and Autochief

/ 59 / 5-Jun-08

Kongsberg MaritimeFuture Engine Performance system

KM is developing a complete set of engine monitoring and performance applications which aim to:

Improve the vessel operation costwiseImprove the safety of the enginesCreate descision support reports

All applications can run standalone, but will have added value of being integrated with the K-Chief 500 system

Kongsberg MaritimeFuture Turbo Charger Performance system

• Turbo chargers are highly stressed parts, which are over-represented on the seizure statistics

• A severe turbo charger problem often starts with a degradation of charger performance

• Kongsberg is currently developing a turbo charger performance monitoring system

• This system is using data from existing temperature and pressure sensors to calculate a charger performance rating

• The system will also be fitted with vibration sensors to warn about mechanical degradation
