The HA OSH150 Helideck Perimeter Light is specifically designed to mark the touchdown and lift-off area (TLOF) on offshore helidecks, providing a reliable and essential safety feature for helicopter operations. This lighting solution ensures pilots have clear visual guidance during landings and takeoffs, even in challenging environmental conditions such as poor visibility or adverse weather. Engineered to meet stringent international safety standards, the HA OSH150 enhances operational safety by clearly defining the critical zones of the helideck.
This perimeter light complies fully with both CAP 437 and ICAO Annex 14 standards, underscoring its suitability for use on offshore platforms and other heliport environments. The light source is a high-power LED that offers a remarkable service life exceeding 75,000 hours, reducing maintenance frequency and operational costs. By default, the HA OSH150 emits a green light, chosen for its excellent color contrast that aids pilots during nighttime approaches and in poor weather conditions. Additionally, the light is available on request in yellow or blue, expanding its versatility for various marking applications. Optional inset perimeter lights are also offered in green and white to clearly mark the edges of the landing area and approach lines, further increasing safety and visibility.
The term Touchdown and Lift-Off Area (TLOF) refers to the designated and prepared zone on a heliport where helicopters safely land and take off. The TLOF is a critical element in heliport design, providing a stable and predictable surface to facilitate efficient helicopter operations. This area is typically situated within the center of the Final Approach and Takeoff Area (FATO) and is surrounded by a clear, obstacle-free zone to prevent interference with helicopter movements. The surface of the TLOF may vary widely depending on the location; it could be a concrete pad, a specially marked rooftop, or part of an offshore platform. Proper lighting, especially perimeter lights like the HA OSH150, plays a vital role in defining this area during night operations or poor visibility, helping pilots discern boundaries precisely and reducing the risk of navigational errors.
The HA OSH150 is designed to withstand demanding conditions, featuring dual M20 cable glands for secure connections and a robust construction that operates reliably within a wide ambient temperature range of -40°C to +60°C. Its compact dimensions of 160 x 244 x 150 mm make it suitable for various installation requirements. The power supply accommodates a wide voltage range of 90–264 VAC at 50/60 Hz, providing compatibility with standard offshore electrical systems. Furthermore, the device is certified under the ATEX Zone 2 standard (ATEX/IECEx II 3 G Ex nA IIC T5), ensuring safe use in potentially explosive atmospheres. Compliance with EASA ADR, UK CAP 437, and ICAO Annex 14 Volume II for Heliports guarantees that the HA OSH150 meets or exceeds all necessary regulatory requirements for aviation safety.
With a light output exceeding 30 candelas, the HA OSH150 delivers bright, clear illumination essential for pilot navigation and helideck safety. Its combination of durable construction, long-lasting LED technology, and compliance with international aviation standards makes it an ideal choice for offshore helideck perimeter marking, contributing significantly to safe helicopter operations in challenging environments.
