ILED Aquarius CIRCLE-H Helideck Lighting System

Why CIRCLE-H?

Helicopter deck signalisation lighting has now taken off into a new direction with the IMT CIRCLE-H Lighting System.

Throughout the industry, it is now fully agreed and accepted that the old method of illuminating the TD/PM Circle and H with flood lights results in the common dangerous problem of creating the disorientating ‘black hole’ effect and at the same time being a source of glare to the helicopter pilots.

Developed with close guidance from the CAA and in full accordance with the requirements of CAP437, IMT’s CIRCLE-H TD/PM Lighting System provides the optimum solution to these problems.

Cleanly and clearly indicating the TD/PM Circle and H, the IMT CIRCLE-H is the only fully certified system of its type – providing optimised safety – without compromise.

The unique integrated mounting plate is able to be customised to suit specific requirements and with a choice of fixing and installation methods to suit all deck types, the CIRCLE-H can be installed as a stand-alone system or as a fully integrated total helideck lighting and status light safety system solution.

IMT understand and fully appreciate that it is not merely about the CIRCLE-H system – but just as – if not more importantly – that it is installed correctly and proficiently. Therefore, IMT have teamed up with selected partners so as to be able to carry out pre installation surveys of helidecks – these surveys and inspections are carried out by fully certified and competent personnel. When installation is taking place off-shore and where the helideck is positioned such that working conditions are liable to be extreme and exacting, then our approved survey and install teams have the following base skill sets as an absolute minimum:

  • CompEx
  • BOSIET
  • MIST
  • Offshore medical
  • IMT approved intallerstatus
  • Mechanical fixing approved installer status
  • IRATA rope access accreditation lead by a level 3 accredited team member
  • Helideck landing area awareness

With regard to “new build and yard” installation – then the necessity for an extreme working conditions trained and fully certified install team is lessened somewhat. So, whatever your install requirements are, be it off-shore, yard, full turnkey or supervised, then IMT has the solution to best fit your needs and legal requirements.

In preparation for installation and to ensure that all issues relating to correct compliance of CAP437, ICAO Annexe 14 and IMO MODU are covered and adhered to, IMT can offer a comprehensive and extensive on-site helideck survey and report service. If you would like further information and advice as to how we can help you in the process of pre-qualifying and preparation for CIRCLE-H installation, then please contact us.

The light characteristics of the CIRCLE-H system are designed in compliance with CAP 437 so that the location of the helideck on the platform is easier to establish and increases its conspicuity. In line with CAP 437 requirements, our CIRCLE-H system has being independently tested and certified – by DEKRA – Attestation of Conformity No: 2168390.01 AOC.

CIRCLE-H is less than 25 mm high, even with the mounting plate. The system is comprised of just 4 main parts. The light unit is easily connected by an Ex-certified, patented plug system. Only cables and conduits are variable – to the D-Value of the helideck.

IMT’s CIRCLE-H system is manufactured from marine grade aluminium – which is by far and away the best material for marine applications and for temperature management control. The one-piece mounting plate is designed so that it can easily be adapted to suit all types of deck construction.
