New helideck regulations apply
As previously announced, new rules regarding helidecks and helideck monitoring systems apply from April 1, 2021. This new regulation, also known as the HCA Standard Helideck Monitoring Systems rev 9b, contains new requirements concerning algorithms and calculations. It applies to FPSO’s, FSO’s, offshore installation vessels, (mega) yachts, offshore supply vessels, diving support vessels and other moving objects, which are equipped with a helideck and operate in European waters.
If a helideck does not comply with the new regulations after April 1, 2021, helicopter operations will be restricted to stable deck conditions (1° pitch & roll, 0.3 m/s heave rate). To prevent this from happening, you need to update both the HMS hardware and software, and install helideck repeater lights, conform HCA rev 9b.
