ORGA - Aids to Navigation and Helideck Lighting Packages

Operators of offshore oil and gas platforms require marking systems, namely aids to navigation, helideck and obstruction lighting packages that are certified for installation in gas hazardous areas, and are capable of functioning reliably with minimum energy demands and maintenance in harsh environments.

Orga has detailed knowledge of national and international standards, regulations and recommendations including IALA, ICAO and CAP437. We provide the optimum solution for the project’s requirements, and deliver high quality and low energy consuming products with low lifecycle costs. Our systems are reliable and long lasting with service intervals of up to 15 years.

Offshore navigation, helideck and obstruction lighting systems

Orga provides customised solutions for the offshore oil and gas industry, including marine lanterns, foghorns, visibility meters, radar response beacons, helicopter deck lighting and guidance systems, helicopter ground power units, remote health-monitoring systems and solar power-supply systems.

CAP437-compliant offshore helideck light systems

The December 2008 version of the CAP437 guidance of the UK CAA indicates changes to helideck light systems, which will have an impact on perimeter lights, floodlights and helideck status lights.

Orga can supply a system in full compliance with the new CAP437 requirements. A new requirement for CAP437 is the introduction of illuminated panels for the touchdown / positioning marking circle and heliport identification marking (H).

This system gives the pilot accurate cueing and positioning information during approach to the helideck.

CAA-compliant LED perimeter lights

Orga can offer green 30cd LED perimeter lights, which have a very long lamp life of 100,000hr, resulting in maintenance savings. The lights should be equally spaced at intervals of not more than 3m around the perimeter of the safe-landing area.

Xenon floodlights for offshore platforms

According to the letter sent by UK CAA to the offshore industry in March 2006, four xenon floodlights have to be installed on the deck at an angle of 90°, equally spaced around the platform, for optimal illumination of the deck.

Helideck status-light systems for offshore structures

A helideck status-light system should be installed if the condition on the offshore structure may be hazardous for the helicopter or its occupants, for example, gas alarms.

The system should be visible 360° around the offshore structure with a flash rate of 120 flashes per minute. It should also be fully automatic and controlled by means of a control panel in combination with the platform's gas-detection system.

Offshore illuminated wind-direction indicators

According to CAP437 requirements, a wind-direction indicator (windsock) should be provided and located to ensure visibility during approach and to indicate the wind conditions at the offshore location.

The windsock should be illuminated for night-time operations by means of an internal floodlight. As an option, Orga can supply windsocks with a low-intensity aeronautical obstruction light included.

Navigation systems for offshore structures

Based on more than 30 years' experience in the offshore industry, Orga will be able to offer you a navigational aid system to mark the offshore structure in line with the IALA recommendations and the European ATEX directives.

Central control panel for offshore navigation systems

Orga will soon be able to supply a compact microprocessor nav-aids central control panel (NCCP), suitable for the operation of lanterns, foghorns and visibility meters.

The inverter-controlled NCCP is based on a standard modular design, which has a lot of delivery, operational and maintenance advantages. The control panel can be supplied with a battery and charger to provide a back-up power.

LED marine lantern

Orga is able to supply an existing six-place lamp changer lantern with incandescent lamps or a new lantern comprising of LEDs. These lanterns operate from a solar system or from the mains-powered NCCP.

Offshore foghorn system

To comply with the IALA recommendation for marking offshore structures, a foghorn system should be installed. The Orga foghorn is designed to operate in harsh offshore environments. Omni-directional foghorns can be supplied in several configurations and sound outputs.

Stainless-steel visibility meters

The Orga visibility meter is based on the back-scatter operating principle, with a long-life LED providing a continuous visibility indication for direct read-out or via telemetry.

The unit is provided with two programmable output contacts for automatic control of the lanterns and foghorns. It is made of stainless steel and provided with self-monitoring functions to ensure long-term installation.

Heavy-duty radar beacons

Orga's heavy-duty radar beacon, in accordance with IALA and IMO specifications, can transmit Morse code characters, which appear on the radar display of a passing vessel. The unit operates in the X and S bands, and can activate the side-lobe suppression.

The radar beacon's built-in self-test and self-calibration capabilities mean it can work unattended.
