Ship Performance Monitoring Display
Danelec / KYMA
New product
The Danelec KYMA KDU-220 is a marine performance monitoring display used within the KYMA Shaft Power Meter and Ship Performance Monitoring ecosystem.
Danelec's official performance literature shows the KDU-220.1 Display Unit connected to the Kyma Shaft Power Sensor SPS-100 and installed in the Engine Control Room. The display presents propulsion information measured from the vessel's rotating propeller shaft, helping engineers and officers understand actual propulsion load and efficiency.
For vessels already operating a Kyma installation, a correct replacement KDU-220 can be an important spare because it allows the existing shaft sensor, signal processing and propulsion-monitoring architecture to remain in service.

Danelec acquired Kyma in 2021 and today continues the Kyma performance-monitoring product line within its vessel-performance portfolio.
The KYMA Shaft Power Meter continuously measures propulsion parameters from the rotating shaft.
According to Danelec's published Ship Performance Monitoring brochure, the following values can be presented on the Display Unit:
The KDU display therefore gives the engineering team direct information about how effectively main-engine power is being transferred through the shaft toward the propeller.
A simplified arrangement is:
Main Engine → Propeller Shaft → KYMA Shaft Power Sensor → Signal Processing → KDU-220 Display
Fuel consumption alone does not tell engineers how efficiently propulsion power reaches the propeller.
Accurate shaft-power information helps correlate:
Fuel Consumption + Shaft Power + RPM + Torque + Vessel Speed
to assess propulsion efficiency.
Danelec describes this relationship as central to optimizing the balance between fuel consumption, power output and ship speed. Its performance systems can also support emissions and operational-efficiency analysis relevant to EEDI, EEXI and CII requirements.
Danelec's current Kyma Power Meter uses strain-gauge measurement on the propeller shaft. Signals are transmitted contactlessly from the shaft ring to the stationary unit, while shaft revolutions are measured using magnets associated with the shaft ring.
Published system accuracy for the Kyma Shaft Power Meter includes approximately:
Torque: better than ±0.5%
RPM: better than ±0.1%
Power: better than ±0.5%
Thrust: better than ±2.0% when fitted as an option.
These are system-level figures from Danelec's Kyma Power Meter documentation rather than specifications of the KDU-220 screen itself.
The KDU-220 also appears in Danelec's Kyma SHaPoLi – Shaft Power Limitation solution.
SHaPoLi is designed to help ships comply with shaft/engine power limitation requirements related to EEXI while retaining access to reserve engine power when required for safety or navigation.
Danelec states that the system provides visual and audible warnings, tamper-proof logging and reporting when reserve power is used. The SHaPoLi system can integrate with Kyma or third-party shaft power meters.
This makes searches such as:
KDU-220 SHaPoLi • Kyma EEXI Display • Shaft Power Limitation Display • Danelec EEXI System
commercially relevant to the KDU-220 product family.
Danelec's published Kyma documentation states that Shaft Power Meter display data can be made available via:
NMEA 0183
Modbus
depending on system configuration.
Broader Kyma performance systems can also integrate information from:
Fuel Flowmeters • Speed Log • GPS • Wind Sensors • Alarm Monitoring Systems • Bridge Instruments • AIS • AMS
to create a more complete vessel-performance picture.
SM MARINE SERVICE™ already lists the earlier KYMA KDU-210 Ship Performance Monitoring Display Unit.
KYMA KDU-210 Ship Performance Monitoring Display Unit
The KDU-210 is another important search term because vessels with older Kyma installations may require replacement displays from different generations.
Published vessel documentation describes the KDU-210 as a flat LCD display and processing unit within a Kyma Ship Performance system, capable of being installed flush-mounted in an ECR console or mounted on a console bracket.
KDU-210 and KDU-220 should not automatically be assumed to be direct plug-in replacements. Hardware, software, communication and vessel-specific configuration should be checked.
SM MARINE SERVICE™ also lists:
KYMA KDU-110 Performance Monitoring System – Shaft Power, Torque & RPM Monitoring
The KDU-110 is an earlier Kyma display generation.
Older Kyma documentation defines KDU simply as Kyma Display Unit and documents KDU-110 installations with multiple display locations depending on vessel configuration.
Connecting KDU-110 → KDU-210 → KDU-220 through internal links is valuable for SEO because customers often know only part of the model or search broadly for Kyma performance monitor / Kyma display unit / shaft power display.
The Danelec KYMA KDU-220 may be used on vessels requiring accurate propulsion-performance information, including:
Bulk Carriers • Container Ships • Crude Oil Tankers • Product Tankers • Chemical Tankers • LNG/LPG Carriers • RoRo Ships • General Cargo Ships • Offshore Vessels • Passenger Ships
Typical users include:
Chief Engineers • Second Engineers • Technical Superintendents • Performance Managers • Ship Managers • Fleet Managers • Purchasing Departments • Marine Service Engineers
Check the vessel supply, external circuit protection, connectors, terminal strip and applicable power-supply arrangement before replacing the display.
Check:
A wrong reading does not necessarily mean the KDU screen has failed.
Check the complete shaft-power measurement chain and verify zero calibration.
Danelec recommends a periodic zero calibration, typically around every six months, for the Kyma Shaft Power Meter system.
Inspect the RPM sensing arrangement, shaft-ring magnets, stationary sensing hardware, signal processing and communication to the KDU.
Check:
KDU model • Software version • Communication protocol • Vessel configuration • Terminal arrangement • Existing controller/sensor generation
A physically similar KDU display should not be considered automatically interchangeable.
For reliable KDU and Kyma system operation:
Danelec states that Kyma shaft-power systems are designed with minimal maintenance requirements and that many systems have remained operational for decades.

KYMA Ship Performance Monitoring • KYMA Shaft Power Meter • Danelec Shaft Power Meter • KDU Display Unit • Shaft Torque Meter • Propulsion Power Monitor • RPM/Torque Display • SHaPoLi System • Vessel Efficiency Monitoring • Marine Performance Monitoring Equipment
This wider product coverage is particularly useful for older vessels where the exact equipment designation may no longer be available in current documentation.
Danelec reports that Kyma has developed ship-performance monitoring technology for more than 30 years, and its Shaft Power Meter systems have been installed on thousands of vessels.
A vessel with a working shaft-power sensor does not necessarily need to replace its entire performance-monitoring system when a display fails.
Correctly sourcing a replacement KDU-220 may allow the ship to retain:
Existing Shaft Sensor • Shaft Ring • Cabling • Stationary Unit • Junction Box • Performance Measurement Configuration
while restoring operational display capability.
That is why new, tested used and replacement KDU-220 units remain valuable marine spare parts.
The KDU-220 is a display unit associated with Danelec/Kyma marine shaft-power and ship-performance monitoring systems. Danelec's own system brochure identifies a KDU-220.1 Display Unit in the Engine Control Room.
In older Kyma documentation, KDU means Kyma Display Unit.
The associated Kyma Shaft Power Meter system presents shaft power, RPM, torque, optional thrust, total shaft energy and total revolutions.
Yes. Danelec's system diagram directly shows the KDU-220.1 as the display for a Kyma Shaft Power Meter installation.
Yes, thrust measurement is available as an option on applicable Kyma Shaft Power Meter configurations.
Danelec's published documentation states that serial output from the Shaft Power Meter display system can use NMEA0183 or Modbus.
KDU-220 appears in Danelec's Kyma SHaPoLi implementation, which provides shaft-power limitation monitoring, alarms and logging for EEXI-related compliance.
They belong to the Kyma display/product family but should not automatically be considered interchangeable. Exact installation and software requirements must be checked.
Compatibility must be evaluated for the specific Kyma installation. KDU-110 is an older display generation documented in earlier Kyma performance-monitoring systems.

These two pages should link back to this KDU-220 page as well. That gives the website a much stronger internal cluster:
KDU-110 ↔ KDU-210 ↔ KDU-220 ↔ KYMA Shaft Power / Ship Performance Monitoring
This structure is stronger for Google than keeping every KDU model as an isolated page.
