Measurements have been carried out on a sample of generic lights that are intended both for the indoor and outdoor use, to establish any likelihood of electromagnetic interference occurring. The results show some of the lights have higher emissions above the recommended limits, in which case risk-based EMC has been used to define mitigation measures for integration to achieve EMC.
Electromagnetic Interference Risk Assessment for the use of LED Lights on Board of Ships
The very high frequency band is a critical band that is used for safety and distress communication on board ships. Use of some commercial off the shelf equipment have been found to cause interference in this band. This paper describes the use of a risk-based approach to evaluate EMC risk due to commercial-offthe –shelf light emitting diodes in the wider band surrounding then very high frequencies, and define measures for the integration without causing disturbance.

RH Marine upgrades systems on the Royal Netherlands Navy ampihibious transport vessel Zr.Ms. Johan de Witt
RH Marine has started with a system upgrade and maintenance of the Zr.Ms. Johan de Witt, the amphibious transport ship of the Royal Netherlands Navy. All navigation, communication, and control systems on board will be renewed and all electrical components will be inspected.
RH Marine allows Royal Netherlands Navy to train emergency procedures on all ships with new MPPT simulator
RH Marine has developed the Multi Platform Procedure Trainer (MPPT) for the Royal Netherlands Navy. This allows the Royal Netherlands Navy Technical Training (KNMTO) to train the situations ashore in a safe situation.
