Risk-based EMC Approach for the Ship's Semi enclosed Reverberant Indoor Environment to evaluate EMI generated by Wireless Devices

Ships are one of the most complex semi-reverberant electromagnetic environments. To lower the cost and weight of the cabling in ships, wired devices are being replaced by wireless ones. This increment, with the presence of the multipath reflective environment, will increase the chance of electromagnetic interference. Although the electronic devices placed within satisfy various electromagnetic compatibility standards, the risk of interference still exists because of the complexity of the environment. A full risk-based electromagnetic compatibility approach can significantly help to mitigate the interference risks. In this paper, we discussed how a semi-enclosed reverberant
environment increases the field strength below the deck of the ship and can cause electromagnetic interference within. We also discussed the risk-based electromagnetic compatibility approach using the Accessibility, Susceptibility, and Consequence cube to overcome electromagnetic interference risks.
