Wind Turbine Import Sequence

 Turbine components manufactured overseas

 Nacelle (generator, yaw drives, controller, and housing)  Rotor (hub, blades)  Tower (2 to 3 sections,)

 Import by heavy‐lift geared ship

 Ship cranes handle minimum 350 ton loads  Wharf to storage by SPMT

 SPMT transport to storage and prep area

 Store on specialized ‘mafi’ units, or  Heavy‐lift crane unloads to ground

Wind Turbine Storage and Prep

 Nacelles adjacent to heavy‐lift crane

 Require minimum of assembly/prep  Moved and stored on “Transport Frame”

 Rotors partially or fully assembled on‐site

 Requires large working area for assembly  Assembled rotor are transported wharf‐side for loading

  • n delivery vessel

 Towers stored horizontally or vertically

 Tower segments usually stored horizontally  Staged vertically for loading on delivery vessel

Heavy‐Lift Crane

Liebherr SLDB 11350

  • Maximum rated load: 1,350 tonnes
  • Boom length: 334 feet (102 m)
  • Assumed maximum lift: 300 tonnes
  • Maximum reach at 300 tonnes: 170 feet
  • 400 tonne moveable counterweight
  • Approximate max concentrated load:

2o,000 psf

Wind Turbine Loading and Delivery

 Jack‐up Delivery Barge

 Capacity for three complete units (nacelle, rotor, tower)  Four to six legs  Lift 20 feet clear in 120 feet of water  Jones Act compliant per Maryland OREC regulations

 Turbine components loaded by heavy‐lift crane

 Crane “walks” 300 tonne nacelle from storage to wharf  Crane lifts and swings assembled rotors to clear legs  Crane lifts tower segments upright and loads on barge

 Tug and barge delivery to OSWE construction site

 Use Chesapeake Channel outbound, may use Chesapeake and

Delaware Canal on return

 Possibly two to three barges in rotation
