What happened
The provided documentation outlines the conclusion of an investigation into an offshore helicopter incident, focusing on the systemic safety gaps identified during the inquiry. While the specific flight details are not detailed in the provided excerpt, the investigation focused on the risks associated with passenger transport in the offshore sector, particularly regarding night operations and emergency response.
The investigation
The investigation examined the operational environment of offshore helicopter transport, specifically looking at the equipment, training, and procedures used during passenger transit to platforms and rigs. The inquiry assessed the adequacy of current cockpit technology, crew training protocols, and the effectiveness of emergency survival procedures for passengers and crew in the event of an immersion in seawater.
Findings
Several critical safety gaps were identified in the offshore transport sector. A primary concern involves the lack of standardized equipment for passenger flights, specifically the need for flight data recorders and automatic voice alerting devices to enhance situational awareness and accident reconstruction. The investigation also highlighted the necessity for better approach guidance systems for helidecks and improved visual cues for pilots.
Furthermore, the inquiry found that crew training lacks sufficient integration of Crew Resource Management (CRM), particularly given the diverse experience levels within the pilot community. Operational manuals were found to be lacking in specific guidance regarding night flying and visual approach procedures. Finally, the investigation noted risks regarding the accessibility of life-rafts and the need for more robust passenger training, such as HUET (Helicopter Underwater Escape Training), to mitigate the dangers of hypothermia and ensure the correct use of survival gear.
Safety action
The following safety recommendations have been proposed to the relevant authorities:
- Mandatory installation of flight data recorders and automatic voice alerting devices for all public transport helicopters.
- Implementation of CRM training as a core component of crew training programs.
- Enhanced requirements for night flying procedures and helideck approach guidance.
- Improved accessibility for on-board life-rafts and the consideration of automatic emergency flotation systems.
- Mandatory HUET training and specialized safety briefings for offshore passengers.
- A review of maritime rescue assets by the State Supervision of Mines and the Coast Guard to reduce survivor immersion time.
