The document summarizes a presentation about offshore wind energy opportunities in Washington State. It discusses Glosten Associates' work in renewable energy and offshore wind. It also outlines Washington's infrastructure assets that could support offshore wind projects, such as shipyards, engineering firms, and research institutions. Finally, it reviews various floating wind turbine concepts and the development stages required to advance floating offshore wind technology.

7. 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
7 Strong Engineering Firms

15. Development Stages
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”)

16. Closing Remarks
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
16 Technology will be ready to apply
