Helicopter Safety and Escape

Helicopter Underwater Egress Training in the United States, and Helicopter Underwater Escape Training in most other countries, (often abbreviated HUET, pronounced hue-wet, hue-way or you-way) is training provided to helicopter flight crews, offshore oil and gas industry staff law enforcement personnel, and military personnel who are regularly transported by helicopters over water.As the name implies, the purpose is to prepare them for emergency exit in the case of a crash landing over water. While the training may be taken by crew and frequent passengers in all small aircraft that could ditch over water, a fixed wing aircraft such as a seaplane or small jet is not as prone to rollover as quickly or sink as rapidly as a helicopter with its main rotor on top of the aircraft. In addition, due to the slow speed of helicopters versus fixed wing aircraft and the lower height above the water, their cabins have a greater chance of being intact with passengers inside when ditched in the water.

The training involves simulated sinking in a pool while rotating the training module upside down and focuses students on bracing for impact, identifying primary and secondary exit points, avoiding smoke inhalation, surfacing for air, and head count. The conventional simulators simulate an immersed cabin rotating around single axis, usually lengthwise. While the traditional simulators can only be turned left or right in the horizontal plane, the new generation simulators can turn 360° in both the horizontal and vertical planes. The HUET training aims to increase time-saving awareness of situational characteristics that can prevent successful escape, such as the role of the seat belt to control excess buoyancy caused by the safety suits inside the helicopter, how to operate the external breathing system, and to carefully store away excess seat belt length.

This course in Undertake Helicopter Safety and Escape (HUET) teaches the skills and theory required to improve an individual’s chance of surviving a helicopter ditching in water.
Note: Trainees are required to supply a completed medical clearance prior to starting the course, using the HUET Medical form.
Prospective trainees should note that the Basic Offshore Safety Induction and Emergency Training (BOSIET) course includes the HUET competency along with the other required competencies to work offshore.
DESIGNED FOR: Personnel who are required to regularly travel by helicopter over water
CONTENT: It is essential that competence be demonstrated throughout the
duration of the course:
• Offshore helicopter operations and general safety
• Psychology and physiology of sea survival
• Personal protective and emergency equipment deployment techniques, lifejacket use and operation
• Helicopter abandonment procedures – surface and inverted
• Individual and group survival techniques
• Life raft operation and deployment techniques
• Personal protective and emergency equipment deployment techniques, lifejacket use and operation
Note: Denture problems may restrict participants ability to complete the EBS competency.
