USCG Roles & Responsibilities for US Offshore Wind • Mission: to ensure the Nation's maritime safety, security and
stewardship.• Statutory requirements for:
–maritime safety, security, mobility–national defense, and –protection of the marine environment.
• Cooperating agency for NEPA purposes. Provide to the Lead Permitting Agency (BOEM) recommendations and identify potential impacts off offshore structures on:
–safety of navigation for the entire maritime community, –the traditional uses of the particular waterway (MTS), –other USCG missions (SAR, MEP, Security)
• USCG NOT A GO/NO GO AGENCY. WILL NOT APPROVE/DISAPPROVE PROJECT
USCG’s Collaboration with Offshore Wind Stakeholders
• Pre-application (bid):–Frank discussions–Identify potential challenges & problem areas–Ensures complete stakeholder outreach–Discusses process going forward
• Post award–Preparation of Site Assessment Plan (SAP)–Preparation of a Construction and Operation Plan (COP).
COP should include complete description of wind farm.–USCG provides guidance for a Navigation Safety Risk
Assessment (NSRA)–Preparation/submission of a NSRA
Navigation Safety Risk Assessment• A NSRA is an assessment of the risks to navigation and identifies and
evaluates potential mitigation measures.• NSRA completed by the developer• Coast Guard provided guidance /information
–NVIC 02-07 (being updated)–Marine Planning Guidelines (MPGs)–Atlantic Coast Port Access Route Study (ACPARS)–AIS data if available
• Reviewed by Coast Guard• Recommendations provided to Lead Permitting Agency and developer
concerning the assessment and identified mitigation measures
USCG & OSW•BOEM - overview of a preliminary framework to help determine where future renewable energy leasing areas may be considered on the Atlantic OCS•Balance competing interests offshore•Parse out the ocean
-Identifies where wind farms can be built-Protects the Marine Transport System-Assesses competing interests offshore-May require development of a formal routing system along the Atlantic coast-Protects mariners-Protects the environment
•GOLDEN OPPORTUNITY FOR MARINE (SPATIAL) PLANNING
Framing the Opportunity
Average turbine size trails latest technology. For example Europe:
2016: Average size turbine was 4.5 MW and in 2017: 5.5MW
Scenario for USA
2020-2025: 4000MW with average 8MW turbines = 500 turbines
2026-2030: 6000MW with average 12MW turbines = 500 turbines
Total 1000 Turbines

Synchronization and Multiple Wind Farms
Synchronization can be staggered and overlapping
•Mindful of weather down-time which impacts differently the range of vessels based on:
•Wind speed & wave height
•Vessel waiting conditions and loaded transit speed
Multiple Offshore Wind Farms:
•Proximity matters especially for Operations & Maintenance where there could be sharing of CTV and SOV (Taxi, Hotel, Store and Workshop) as well as occasional use of Jack-up Vessel
•Given O&M is ~ 30% of life time cost, vessel utilization has a significant financial impact to the operator’s bottom line.
