Kongsberg HMS 300 Helideck Monitoring System

Offshore helicopter operations are carried out in hostile environments.

The HMS 300 is designed to measure helideck motion during helicopter

pre-landing and on-deck operations to improve flight and passenger

safety in these conditions. The system monitors the helidecks

acceleration, heave velocity, inclination, roll and pitch together with

meteorological data in real-time.

The HMS 300 is fully compliant with the prevailing recommendations

and guidelines issued by the Civil Aviation Authorities in UK, Norway

and Brazil. The HMS 300 is compliant with the CAP 437 from

September 2018 and accompanying Helideck Certification Agency (HCA)

document revision 9b. This imply that the helideck must be equipped

with repeater lights connected to the HMS 300 system to indicate to the

pilot whether the on-deck or pre-landing conditions are within the landing

limits or not. The HMS 300 is compliant to NOROG ver. 9.2 for the

Norwegian sector and NORMAM-223/DPC for the Brazilian sector.

Data monitoring and presentation

The HMS 300 will calculate and present the Motion Severity Index (MSI)

and Wind Severity Index (WSI) data together with significant heave rate

(SHR), inclination, roll and pitch of the helideck in real-time.

The system utilizes the KONGSBERG MRU models (E, H, 3. 5 or 5+) or

the MGC models (R2 or R3) to precisely monitor vessel motion and

accelerations in the helideck center. These data are transferred to the

HMS Processing Unit that processes helideck motion data together with

MSI and WSI figures to determine whether the helicopter operation is safe

or not.

Web access

Live vessel data can be made available from the HMS 300 installation when

connected through the KONGSBERG K-IMS cloud based digital platform

(optional). The Web access will be available to customers through a paid

service. The Web service is developed to assist helicopter operators to plan

the flight prior to take-off from the heliport.

Both onboard and onshore personnel can monitor helideck movements and

meteorological data in real-time and see the same operational picture in

order to increase operational awareness. Cyber security is an important part

of the system. With this cloud-based service, storage of helideck data for

months is included.
