Washington State Assets and Infrastructure
1. History of Innovative, Major Offshore and Marine Construction Projects• Sealifts in 1970’s and 80’s supported Prudhoe Bay
Development and Alaska Pipeline Construction • Floating Bridges (new 520 bridge underway)• Tacoma Narrows Bridge – Cassion Installation
2. Major Marine Construction Firms with Equipment Based in Puget Sound• Manson Construction• Kiewit General• Cable Laying
3. Many Shipyards and Fabricators with Large Steel Through-put Capability, Supported by Strong Engineering Firms

Washington State Assets and Infrastructure
4. Oceanographic Research Support• U/W School of Oceanography and R/V Thompson• U/W Applied Physics Lab (APL)
5. Materials Transportation Infrastructure Strong• Tug and Barge Companies (Foss and Crowley plus
many more)• Rail Access to Waterfront Loading (Boeing Mukilteo
example)
6. Fabrication, Assembly and Staging Areas Plentiful (no water depth or air draft limitations)• Grays Harbor• Port Angeles

Research to Prove Feasibility• TRL 2 = concept development• TRL 3 = simulation
Technology Development• TRL 4 = basic model testing• TRL 5 = complete model test program
Technology Demonstration• TRL 6 = intermediate-scale prototype
deployed offshore
System Commissioning• TRL 7 = full-scale prototype deployed
offshore (“Relevant Environment”)• TRL 8 = full-scale prototype deployed
offshore (“Expected Environment”)
Closing Remarks
16
Floating Offshore Wind is Viable• Within 5 years we will see 4 full-
scale demonstration projects• Cost of Energy will be driven down
with technology developments• There will be a few platforms with
acceptable technology, each with advantages that suit different sites/turbines
European & Asian Initiatives will Develop Technology
When Washington State is ready for Offshore Wind, Floating Technology will be ready to apply
