2. Alpha Ventus - The Project
• April 6th 2009:
Positioning of an Eurocopter EC 135
P2+ at Emden (EDWE) airport
• Transport of Personnel to the Offshore
Instalation „Alpha Ventus“
• July 8th 2009:
Beginning with Hoist Trainings for the
Wind Power Plant Technicians (more
than 280 trained until now)
• Since October 2009:
Performing Offshore Hoist Missions at the Wind
Power Plants (more than 4400 performed since then)

3. Requirements by Law
JAR OPS 3
(Joint Aviation Requirements for the Safe Transport of
Passengers by Helicopter)
Offshore General
• JAR OPS 3.465
Weather minima for Offshore Operations
• JAR OPS 3.660 and 3.825 – 3.843
Required Equipment for Offshore Operation (such as Survival Suits,
Life Rafts, Survival Vest and Radar Altimeter)
Performance Classes
• JAR OPS 3 Subpart F to I (performance class I to III)
Hoisting
• JAR OPS 3.005 (h)
• Recomendations from the ICAR
(International Committee of Alpine Rescue)

3. Requirements by Law
Additional: National Draft Law
(NfL II-XX WKA, not implemented)
Suggested Requirements on Wind Power Plant:
• Power Plant not working, Rotor NOT turning!
• Rotor in Y-Position
• or: Rotor Blade horizontal, in Approach Direction

3. Requirements by Law
Suggested Requirements on Wind Power Plant (contd.):
Wind Direction
• Position of Generator Housing:
fixed and perpendicular to Wind Direction

3. Requirements by Law
• In case of a malfunction with maintenance action
required at the Wind Power Plant:
No possibility to comply with drafted requirements on
wind power plant (Position of Rotor, Position of
Generator Housing), requirements not acceptable!
• Test flights at WEA RePower 5M
in Cuxhaven on May 23rd 2009:
to establish safe operational
procedures and limitations

3. Requirements by Law
• Testing of following condions:
- Normal Hoisting (Generator Housing
in 90°-Position)
- Normal Hoisting, Rotor windmilling
- Predefined Positions of Rotor and Generator
Housing
- Dead Turbine (random position)
• Procedures and Limitations have been
defined, documented and submitted to
the Aviation Authority (LBA)

4. Principles of Operation
Minimum:
5 - 7m above platform
In case of OEI:
approx. 2m loss of
height!

4. Principles of Operation
- HH-Pax ready to hoist
- Door open (< 60 Knots)
- Equipment check
- Attaching the hoist hook
- Equipment check
- Attaching to the securing line
- Leaving the seat
- HH-Pax leaving the cabin
- Last Equipment check
- HH-Pax still attached to securing line
- Hovering appr. 5 to 7 m above the platform
- Powercheck
- Detaching the securing line
- Anti static line handed to the passenger
- HH-Pax is reeled down
HTM has adapted the ICAR
Standards to their Offshore
Operational needs
- HH-Pax on the plattform
- Signal: Hoist cable free
- Cable is reeling in
Next hoist cycle or departure

5. Procedures for Barges
Test Flight to establish Procedures for Hoist
Operations on Jack Up Barge „GOLIATH“
Established Procedures
contain:
• Hoist Positions
• Communication with Barge
Crew
• Power Check
• Danger evaluation on boat
• Hoisting with Harness or
Rescue Seat / Triangle

6. HSE Development example
Accident AV 5 on the
27th of November 09
• Technician suffered severe injury
• Due to location and weather:
difficult rescue mission
• Mission turned into a long lasting and sometimes
crtical operation
• Normal stretcher was used, hazardous
aerodynamic effects
• Reason for establishment of HSE procedures
for rescue missions from the jacket platform

6. HSE Development example
Developement of Hoist Procedure from the Jacket
Procedure from Jacket only perfomed, if:
• Transport by ship to transformator platform not
possible
• Helicopter Crew is briefed
• At least 2 trained persons on Jacket Platform
• Radio Contact between Helicopter and Jacket
• Preferably a doctor should be hoisted up with the
patient in the hoist bag
