Helicopter Operations

Outline Preparing for a helicopter evacuation Lift techniques: Direct lift High-line transfer Alternative small boat technique

General Considerations Helicopter operations typified by: Strong downdrafts / spray High noise levels Static electricity Always obey signals and directions from the helicopter crew

Preparing for a Lift Prepare boat As helicopter approaches: Wind direction Secure loose objects Remove obstructions Clear area for lift Wind 20o to 40o on port bow Wear facemasks for spray protection Maintain constant speed and heading As helicopter approaches: Obey helicopter crew’s instructions (radio or visual) Crew will determine type of lift Helicopter will position itself relative to the boat

Direct Lift Can be used on boats of all sizes Don’t touch the Winchman! Let the winchman or trailing line touch the boat/sea first

High-line Transfer (1) Used where obstructions/boat motion a problem Let the line touch the boat/sea first Don’t tie the line to anything Keep line clear of obstructions

High-line Transfer (2)

High-line Transfer (3)

High-line Transfer (4) Take up slack in the line Don’t try to pull the winchman towards you Use line to guide winchman over deck

High-line Transfer (5)

High-line Transfer (6)

High-line Transfer (7)

High-line Transfer (8) Pay out line as winchman moves away

High-line Transfer (9)

High-line Transfer (10)

High-line Transfer (11)

Small Boat Technique Preparation Boat deploys sea anchor or anchors Wind direction Wear facemask for protection from downdraft / spray Helicopter will position to winch directly into boat Sea conditions may dictate variations – always follow helicopter crew’s instructions

Summary Helicopter operations are typified by: Strong downdrafts / spray High noise levels Static electricity Prepare boat in advance: Loose articles / obstructions Wind direction Sea anchor / anchor Lift techniques: Direct lift - high-line transfer - small boat Always obey signals/directions from the helicopter crew
