Kongsberg Engine Performance Systems Safety and efficiency for large bore engines
Kongsberg system philosophy
A crystal clear solution
Kongsberg Maritime, as a supplier of integrated ship systems, plays an increasingly important role when optimizing the operation of vesls. Extensive investments in rearch and development have resulted in a modular concept, which contributes significantly to improved fuel efficiency and reduced emissions. The engine performance concept enables permanent online monitoring and diagnosis of propulsion and auxiliary engines for 2-stroke and 4-stroke engines and forms the basis for condition bad maintenance (CBM).
Partnership
In its quest to offer the best in environmental solutions for the shipping industry, KONGSBERG has t
eamed up with AVL List GmbH to offer an engine performance monitoring system that enables continuous monitoring of engine condition and performance. In combination with a powerful decision support system, engineers have an easy to u tool for maintaining main and auxiliary engines at optimum performance.
cad注册Modular and scalable concept
Systems may easily be extended by adding additional hardware units such as operator stations, input/output modules and additional measuring points.
Kongsberg System T echnology offers signal acquisition and processing units for installation in ER cabinets, ECR consoles or mounted directly on the engine. Processing algorithms are executed within the local acquisition units or in the powerful controller units. By distribution and gregation the conquences of a system fault are reduced and may even be eliminated.
The Kongsberg
Engine Performance System concept yields a modular design, where
various modules can be configured and combined to suit individual needs. Engine Performance Syst
ems can be integrated with the Kongsberg K-Chief automation system.

NK 600 - MIP® calculator - a basic building block The basic engine performance solution
The Kongsberg NK 600 MIP® calculator is the basic engine performance solution providing the operator an instant status of main engine operational performance bad on engine cylinder pressure signals.
Main Benefits §Modern touch screen interface §Integration with K-Chief AMS §Online and offline solution §Basic building block for advanced diagnosis system for new builds and retrofits §Warranty of cylinder pressure nsor is 3 years or 16000 running hours
General description
MIP is an abbreviation for Mean Indicated Pressure, which is a calculated average

cylinder pressure throughout one complete engine cycle. MIP is a parameter reprentation of the actual work created by the combustion inside the cylinder.
NK 600 is the 6th generation engine condition monitoring system from KONGSBERG. Two alternative configurations are available:§BASIC and mi-automatic system with one common portable pressure nsor §ONLINE and fully automatic with fixed pressure nsors on each cylinder for
continuous monitoring

Engine optimization
The engine performance and optimization module is an extension of the Kongsberg K-Chief system. The K-Chief system integrates the AVL engine performance & TM optimization system (AVL EPOS ) and the torque measurements as well as other performance monitoring nsors, providing a complete solution for engine monitoring.
TM The AVL EPOS is a step change for traditional engine condition monitoring. Years of design and operational experience has been analyzed and systemized in a
