The joint proposal to applicate risk based EMC regulations has been accepted and will be implemented January 2017. The intention of this proposal is to reduce EMC related costs by applying a risk based approach combined with smart installation methods. The proposal has been submitted by the “EMC for future ships” work group. Partners of RH Marine in this work group are: Damen, Thales, DMO, Lloyd’s Register and University of Twente.
Risk based approach
EMC stands for Electromagnetic compatibility, meaning that equipment won’t be interfered by phenomena such as radio frequency fields and switching transients. Neither may the equipment cause such levels of interference that other equipment suffers from this disturbance. Complying with these regulations is often experienced as a challenge, for all markets.Until now, the Lloyd’s Naval Rules offers two options to deal with EMC. One option requires the application of equipment that complies with the maritime EMC standard IEC60533 (which is hardly available on the market); the other requires use of equipment that complies with an appropriate naval standard, MIL-SPEC (expensive and possibly outdated).
Wider selection of equipment
Neither of the two options considers that even when equipment complies with the standard it is still possible that interaction between equipment can cause interference. The new option, which can be used from the beginning of this year, is that a risk based approach is followed. This enables a more flexible selection of equipment, as long as the combination proves not to cause interference or to suffer from disturbance.
For now these new rules apply only for Naval ships built under the Lloyd’s Naval Rules. However, if the pragmatic and cheaper approach is suitable for the most demanding segment in ship building, it will also be a good solution for the other segments. Therefor the consortium will continue to promote this EMC approach for other types of ships, with other classification societies and in military and civilian standards.
Setting the standard
RH Marine is an innovative system integrator with worldwide leading EMC knowledge and in-field experts. RH Marine is completely ready to work according to this new option and advise you about the practical implications of this new regulation. The improved standard enables electrical system integrators with sufficient EMC knowledge to deliver reliable, up to date and easy to maintain installations for the right price.
This is a perfect example of RH Marine applying its in-depth EMC knowledge on a system level to improve the industry standard for the vessels of the future. RH Marine’s philosophy is to optimise the vessel as a whole for its mission, instead of optimizing individual components.
