Staging Port Activities Wind Turbine Generator Import
Import turbine components Buffer import against installation
Wind Turbine Generator Installation Pre‐installation assembly and prep Loading installation or delivery vessel
Support Structure and Foundation Fabrication Import of foundation materials Foundation fabrication Loading foundation delivery vessels
Maryland Energy AdministrationSeptember 3, 2014
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
Maryland Energy AdministrationSeptember 3, 2014
Import Vessels and EquipmentHeavy‐Lift Geared Ship• Length: 452 ft.• Beam: 75 ft.• Laden Draft: 31 ft. • DWT Capacity 15,000 tonnes• Cranes: 2X 400 tonnes
(combinable to 800 tonnes)
Self Propelled Modular Transporter (SPMT)• Capacity: 25 tonnes/axle unit• Vertical adjustment: 2 ft.• Speed: 3 miles/hr (264 ft./min)
Maryland Energy AdministrationSeptember 3, 2014
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 on delivery vessel
Towers stored horizontally or vertically Tower segments usually stored horizontally Staged vertically for loading on delivery vessel
Maryland Energy AdministrationSeptember 3, 2014
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
