SMC Helideck Monitoring System for offshore environment
The SMC Helideck Monitoring System meets all the criteria of the current international code requirements for offshore helideck operations, including all of the following standards:
- UK CAA CAP437
- UK HCA (Helideck Certification Agency) Standard Helideck Monitoring Systems Revision 8, Revision 9
- Norwegian requirements CAA BSL D 5-1
- Brazilian DPC Normam-27
New rules for helidecks and helideck monitoring systems
HCA Standard Helideck Monitoring Systems Rev 9b is the latest set of national and international standards, which are applicable to all moving helidecks operating in European waters.
The purpose of the revised standard is to ensure adequacy and uniformity of readings/registration of helideck movement and weather conditions. A helideck mounted on a floating unit such as a vessel or superyacht, floating production unit (FPU), semi-submersible rig or floating jack up rig and other helidecks shall be considered to be an unstable/moving landing area if the pitch or roll exceeds 1 degree either side of the vertical and if the vertical movement of the helideck exceeds 0.4 metres/second. The new standard requires updates on the hardware and software and installing helideck repeater lights to comply with HCA Rev 9b.Download Standard Rev 9b Download Standard Rev 9b Download Standard Rev 9b
New requirements on measurements, displays and indicators
The new standard requires the system to provide sufficient integrated information from sensors, numerically displayed in relevant locations on the vessel or installation, for easy communication with helicopters in flight and the helicopter land base operations.
To comply with new regulations, existing Helideck Monitoring Systems must be upgraded to display integrated information from sensors for helideck movement, wind and other meteorological data. Since the HMS operates in two distinct modes, ‘Pre-Landing’ and ‘On-Deck’, two separate displays are required. New graphic layouts with motion severity index (MSI), wind severity index (WSI) and measure of motion severity (MMS) are required to be presented. A repeater light system, which is identical to that presented on the ‘Pre-Landing’ and ‘On-Deck’ displays, must also be installed to indicate the helideck operational status to the helideck crew and helicopter flight crew.
Standard components of Helideck Monitoring System
Fixed installations, semi submersibles, crane/lay barges, FSUs, large ships, drill ships, FPSOs and jack up rigs all are required to have the full list of motion and meteorological instruments. Smaller vessels and vessels with less frequent helicopter operations, such as DSVs, support and seismic vessels along with tankers and super yachts, require only motion, wind, air pressure, temperature and dew point information.
