Transport Equipment
Transporting systems increasing safety and
ensuring transport with less component damages
Tower transportTransport nacelle rear end
Transport frame for hub
 All handling / lifting performed without touching the component
 Transport equipment mounted at production facility and used until
pre-assembly / installation
 Transport damages reduced to a minimum
 Cost reductions and increased safety due to reduced number of
lifting operations
 Only one option for lifting the components
 Reduction of heavy lifts for personnel (slings, shackles etc.)
 Tower transportation equipment also used for lifting
What we achieve…
Transport frame for hub
Complete nacelle at the pre-assembly site ready for functional test
 Assembly of nacelle rear end, generator and hub
 Mounting of turner tool
 Functional test of the complete nacelle before it is shipped to site
On the pre-assembly site…

Transport Equipment
The art of transporting 75 m blades from
production to site in the safest and most cost-effective way
• All equipment mounted at production site and used during
transport to pre-assembly site
• Main lifting eyes for single point lifting, i.e. lifting operations
performed only in transport equipment without touching the
component
• Friction pads on tip clamp for ensuring optimal fixation of the
blade in correct position and elimination of transport
damages
• Possible to transport blade with stud bolts and blade bearing
cover mounted from production
 Transport damages reduced to a minimum
 Number of handlings reduced
 Reduction of heavy lifts for personnel (slings, shackles etc.)
 Cost reductions and increased safety due to reduced number of
lifting operations

How to move 75 m blades internally
without compromising flexibility and safety?
• Consists of two parts – root end and tip end mover
• Enables flexible blade transport at production facility / harbor
• Tuck master for root end / tip end remote controlled by technician on
ground = high maneuverability
• Cost reductions and increased safety due to reduced number of
lifting operations

Logistics / Sea-fastening
Logistics during load-out and installation
• Single blade concept chosen to utilize the space onboard the vessel
and at the quay side in the best possible way while at the same time
allowing for higher installation wind speed
• Deck layout is prepared to allow for towers and nacelles to be
loaded using the vessel crane while blades are being loaded
simultaneously using shore cranes
• All sea-fastening is pre-installed on the installation vessel and
prepared for main components and auxiliary equipment
• Fixed platforms incl. rails and stairways for the blade rack
ensuring easy access and safe working conditions for technicians
How it works…

Logistics / Sea-fastening
How to ensure safe fastening of towers while at the same time
reducing crane time and speeding up installation
• Towers secured by means of pin bolts which ensures easy and safe
mounting and demounting of the towers
• Everything is pre-mounted and the tower can be lifted directly from the
harbor to the installation ship thereby reducing crane time
• Platforms incl. rails and stairways for easy access also ensuring safe
working conditions for technicians
• Implementation of partly hydraulic sea-fastening solution has reduced
installation time even further
• The hydraulic sea-fastening is design approved by DNV
How it works…

Nacelle secured only by means of corner stoppers
ensuring shortest possible crane time
• Nacelle lifted from harbor and landed on the vessel deck where it is secured
only by means of corner stoppers (no other sea-fastening required)
• With no additional equipment needed, crane time is reduced to a minimum
• All sea-fastening is approved by the MWS
• All used equipment is returned on the empty nacelle frame
How it works…

Blade rack design reducing lifts and manual handling during
load-out while at the same time easing installation
Tip end sea-fastening
Root end sea-fastening
• Blades positioned slightly offset in blade rack making it possible to
always lift the top blade for installation
• Same interface used for transport and sea-fastening at the blade root
end
• When lifting the blade onto the vessel, blade root end is secured in the
blade rack by means of a pin ensuring no uplift and no sideways
movement
• For installation, root end equipment bolts are loosened, and the blade
can be lifted directly - without demounting sea-fastening
• At the tip end, the blade is secured by means of crossed slings which
can be opened to allow for direct lifting of the blade
• All in all – crane time is reduced to an absolute minimum
How it works…

How to ensure fast and safe
full tower lifts at high wind speeds?
• Gripper is designed for installation at an average wind speed of 14 m/s
• Stairways and platform integrated for safe and easy access
• Reduction of lifting brackets and loose parts improving safety and reducing
heavy lifts for technicians
• Only fiber pads touching the tower flange
• Tower cover remains mounted during lift
• Only mechanically operated - no hydraulics / electrical systems
• Traverse system enabling rotation of tower for alignment on TP, ie. no
manual handling
• Full GL approval – design, production and load test
How it works…
What we achieve…
 Reduction of installation time compared to traditionally bolted lifting
brackets
 No damages to towers due to fiber pads
 Increased safety and improved working
environment for technicians

How to safely install a 350 t nacelle 110 m above water level
• Designed for installation at average wind speed of 14 m/s
• Trunnion has the same design for all three lifting devices for our main
component lifts: tower, nacelle and yoke
• Integrated stairways for safe and easy access and preparatory work
• Three-point lift ensuring stable positioning of the nacelle
• Remote-controlled horizontal adjustment during lift
• Reduction of lifting brackets and loose parts improving safety and
reducing heavy lifts for technicians
• Full GL approval – design, production and load test
How it works…
What we achieve…
 Reduction of installation time compared to other known solutions
 Increased safety and improved working environment for technicians
 Future-proof – designed for next generation nacelles

A flexible giant enabling single blade installation
of B75 blades in average wind speed of 14 m/s
• Single blade installation in average wind speed of 14 m/s
• Dedicated sea fastening frame incl. stairways and platform
• Fully automatic - using a remote control, a technician is able to control the fixation of slings
around the blade
• Data collection allowing for documentation of all lifting operations
• Patented design
• Yaw function allowing for blade adjustments in height while maintaining tagline tension
• Active tilt function allowing horizontal adjustment during installation
• Pitch function is build into the yoke
• Full DNV approval – design, production and load test
How it works…
 No working in heights and no manual
handling of slings improving safety and
reducing installation time
 Preparatory work can be performed without
cherry pickers due to integrated stairways and
platform
 Yaw, tilt and pitch functions allowing for
adjustment of the blade during installation
What we achieve…
