System philosophy
Modular and scalable concept
Utilise open standards for automation systems
Systems may easily be extended by adding additional hardware units such as
operator stations, input/output modules and additional measuring points.
Kongsberg System Technology 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 segregation the consequences of a
system fault are reduced and may even be eliminated.
The Kongsberg Engine Monitoring Systems concept yields a modular design, where
the various modules can be configured and combined to suit individual needs.
The individualised Engine Monitoring systems can then be integrated with
Kongsberg K-Chief and AutoChief C20 system. Each module is fully compatible with
each other and therefore provides seamless information sharing and a consistent
operation environment.
Essential components such as bearing wear sensors and wireless temperature sensors
yield the best results that technology has to offer in terms of reliability, accuracy and
durability. By utilizing the CAN field bus protocol for engine instrumentation,
installation costs are reduced and the quality of data processing enhanced.
The engine monitoring functionalities have been developed in close co-operation
with maritime professionals, to ensure system functionalities that work effectively
and safely in real life operations. The Kongsberg Engine Monitoring System concept
in general and the individual modules utilise open standards, which provide for
interfaces to different automation systems.

Avoiding open-up inspection
Condition monitoring of crank-train bearings in two-stroke
diesel engines
The Kongsberg Bearing Wear Condition Monitoring (BWCM) system measures and
displays the combined physical wear of the crosshead, crank and main bearings,
providing early bearing seizure warnings if problems occur during engine operation.
The sensors are specifically designed to provide reliable and accurate measurements
over years of operation inside the engine.
The BWCM system uses two sensors mounted in each cylinder compartment,
measuring every time the crosshead passes Bottom Dead Centre. The Kongsberg
BWCM sensors perform individual compensations for engine speed, engine load
(cpp) and engine crank case temperature.
Main Benefits

Avoiding open-up inspection
Avoiding open up inspection
The Kongsberg BWCM system is designed according to the specifications of MAN
Diesel & Turbo and received a Type Approval according to Germanischer Lloyd’s (GL)
Guidelines for Machinery.
The following systems are part of a class survey arrangement:
§BWCM system
§Water in Oil sensor
§Shaft Earthing Device (owner or yard supply)
§Computerized Planned Maintenance System (owner or yard supply)
Water in Oil sensor
The Kongsberg Water in Oil sensor enables fast and reliable detection of moisture in
oil. It can be used in online moisture monitoring and as a control device.
The water in oil sensor measures moisture in oil in terms of the water activity (aw)
and temperature (T). Water activity indicates directly whether there is a risk of free
water formation. The measurement is also independent of oil type and age.
The sensor incorporates the latest generation of the HUMICAP® Sensor, which is the
result of ten years of field experience. It was developed for demanding moisture
measurement in liquid hydrocarbons. The sensor's excellent chemical tolerance
provides accurate and reliable measurement over a wide measurement range.
Main Benefits
§According to MAN Diesel and GL specifications condition based overhaul of
crank-train bearings
§Dual sensor for continuous measurement of moisture in oil and oil temperature
§Ball valve installation, no need to shut down the process
§Easy to maintain in the field
WATER IN OIL SENSOR
Additionally required by MAN Diesel and GL for
condition based overhaul of the crank-train
bearings

Unique temperature monitoring - bearings and liners
SENTRY - For crankpin and crosshead bearing temperature
monitoring
The SENTRY wireless bearing temperature monitoring system is capable of
continuously measuring the metal temperature of bearings during engine operation.
Main components are:
§Wireless temperature sensor
§Stationary reading antenna
§Signal processing unit
The wireless sensors are individually interrogated from a multiplexed Signal
Processing Unit (SPU) using a high frequency and low energy radar pulse. The radar
pulse is transmitted to the wireless sensor via a coaxial cable to a stationary antenna
positioned inside the crank case. Within the interrogation range of the stationary
antenna the sensor responds to the radar pulse by reflecting a pulse pattern back to
the SPU. The characteristics of the reflected pulse are uniquely defined by the
temperature.
Main Benefits
§Continuously measuring metal temperature of the bearings for fast
response time
§Passive sensor, no battery required
§Proven and reliable technology
§Type approved to replace Oil Mist Detectors

WIRELESS TEMPERATURE SENSOR
Main bearing temperature sensors
Custom designed main bearing temperature sensors can be fitted into any type of 2-
stroke and 4-stroke diesel engines. On 2-stroke engines the sensors are mounted on
the main bearing girder with the tip of the sensor in direct contact with the bearing
shell. The sensor measures the combined temperatures of the bearing shell and of
the lubrication oil that flows from the bearing. On 4-stroke engines the sensors are
inserted in the main bearing cap.

Monitoring cylinder liner temperature
The Kongsberg cylinder liner monitoring system monitors the piston running
performance by measuring the temperature of the upper part of the cylinder liners.
Increased friction between the piston rings and the cylinder liner creates an elevated
temperature level leading to abnormal liner wear and potential piston ring breakage.
Temperature alarm limits can be individually set on the PC work station to give early
warning about high thermal load and potential cylinder liner scuffing.
The Kongsberg cylinder liner monitoring system consists of high quality temperature
sensors and one field-bus signal converter on each cylinder and one common
Operator Station. Additionally, individual relay output alarms can be provided
directly to the cylinder lubrication units in order to temporarily increase the cylinder
lubrication.
Main Benefits
§Tailor made to the Wärtsilä MAPEX PR condition monitoring system
§Also used to send scuffing alarms to the MAN Diesel Alpha Lubricator
§Easy to refit on MAN Diesel and Wärtsilä engines
§Field-bus signal converters (CAN Open) installed directly on engine block
