Upcoming Helideck Regulation Revision
October 1, 2025, the CAA UK CAP437 Standards for Offshore Helicopter Landing Areas 9th Ed. & the Standard Helideck Monitoring Systems Rev. 9c. take effect.
Are you compliant?
Most moving helidecks must comply with CAP437 and/or ICAO Doc. 9261, which means there are important changes in the regulations that you need to consider, for example:
- The positioning of the MRU
- The sample rate of the wind sensor must be 4 Hz
- HMS 9c Software
- HMS 9c Site Acceptance Test

ShoreConnection International’s new HMS 900 9c software and documentation package is designed to meet the compliance requirements and will be ready to be rolled out during the first months of 2025. In the meantime, we can perform all upgrades and installations of new equipment so that you are compliant well before the deadline.
