CAP-compliant, low-maintenance helideck marking systems

Products are ATEX- and IECEx-certified and comply with the current CAP 437

By August 2018, all night-time operation of offshore helidecks under British jurisdiction requires marking systems that comply with the new CAP 437 regulations issued by the Civil Aviation Authority (CAA). A major player in oil exploration off the southern UK continental shelf is now taking the lead by retrofitting ten oil rigs with the innovative, CAP 437-compliant Circle & H Helideck Lighting System (CHLITE) from R. STAHL subsidiary Transberg AS. Approved by the Helicopter Certification Authority (HCA), the new CHLITE system is ideal for retrofits, since it can be very easily installed in only 2-4 days. All low-profile lighting products (22 mm) to mark the landing circle and “H” symbol come with fixed cables and require no on-deck junction boxes.

The illumination elements are equipped with six durable, energy-efficient TEF 2440 lights that feature fully redundant power supply. ATEX- and IECEx-certified for zone 1 operation, they provide IP66/67 ingress protection, a T6 temperature class rating, and tolerate environmental temperatures between -30 °C and +55 °C. Users can switch between two different lighting intensities as required. Since new CAA requirements have historically been a model for other countries, retrofits may well become necessary on rigs elsewhere in the world as well.

To complement this major innovation, the Norwegian R. STAHL subsidiary is also introducing two other new products: TEF 2460 dual-colour obstruction lights, which are installed at the helideck perimeter and can be switched from green to red to alert pilots in dangerous situations, and TEF 9970 LED floodlights featuring reduced glare, which minimises irritations for approaching aircraft. Both products are also ATEX- and IECEx-certified and comply with the current CAP 437.
