Maryland Offshore Wind Energy Stakeholders Forum

Agenda12:30 – 1:00 Box Lunch and Introductions1:00 – 1:30 Project Background and Objectives

‐ Project scope‐ Introduction to the MD OSWE site‐ OSWE staging port activities

1:30 – 2:30 Project Findings‐ Turbine installation sequence in MD‐ Turbine staging port requirements‐ Foundation construction requirements‐ Candidate port sites

2:30 – 4:00 Moderated Open Discussion‐ Port options and opportunities‐ Stakeholder input and recommendations‐ Selected action items and additional findings‐ Final Q&A

4:00 – 5:00 Networking and Refreshments


PROJECT SCOPEObjectives:• Identify Baltimore Harbor sites• Solicit expressions of interest

Tasks:• Definition of Needs and Port

Criteria• Inventory of Existing Terminal

Interest


Maryland Offshore Wind Energy Site

Ocean City Maryland Offshore Wind Energy Site

10 Miles


Navigation IssuesChesapeake and Delaware Canal Route• Vertical: 130 ft. at MHW• Horizontal: 450 ft.• Depth: 30 ft. at MLLW• Distance: 150 miles

Chesapeake Channel Route• Vertical: 182 ft. at MHW• Horizontal: 1,100 ft.• Depth: 50 ft. at MLLW• Distance: 290 miles


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


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


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)


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


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
