scope:

This document specifies installation specifications for ship communication networks for improving communication for shipboard equipment and systems that are independent from navigational equipment networks and engine-control networks. However, this does not exclude the application of this international standard to OT networks such as navigational equipment networks and machinery control networks in ship. This International Standard utilizes existing standards relating to protocols, and provides new specifications for such aspects as communication network-system architecture, administration, operation, and installation. The new specifications specifically include: redundancy if necessary for a shipboard communication network system; network administration that does not require experts; physical as well as logical security; and network installation. This standard uses the standard communication network internet protocol This International Standard applies to shipboard wired networks for IP communication, using First Ethernet and Gigabit Ethernet as specified in IEEE802.3 and to shipboard wireless networks for IP communication, using the unlicensed 2,4 GHz and 5 GHz bands as specified in IEEE802.11. NOTE - Other wireless technologies based on non-IP communication such as Bluetooth, Zigbee or wireless communication methods using 920 MHz band are not covered by this document
