TAP-629-Assess the Design and Inspection Criteria and Standards for Wave and Current Energy Generating Devices

The objective of this project was to provide a description of wave and current energy generating device systems and subsystems and provide a functional taxonomy; identify criteria pertinent to the design, construction, installation, maintenance and operations of these systems, and review the criteria to determine applicability, adequacy, and suitability; identify existing codes and standards that can be applied to these devices; conduct a regulatory gap analysis; and recommend regulatory initiatives or approaches for addressing identified deficiencies.

TAP-628-Assess the Design/Inspection Criteria/Standards for Wave and/or Current Energy Generating Devices

Free Flow Energy performed a gap analysis to determine if modifications should be made to engineering specifications and regulatory standards to enable the placement of wave and current energy devices within the outer continental shelf (OCS) without compromising safety and performance guidelines.

The following tasks were accomplished:

Task 1. Acquire basic engineering information and generate a list of engineering concerns.

Task 2. Address safety and regulatory concerns and generate a checklist for the complete spectrum of unique safety concerns.

TAP-627-Assess/Develop Inspection Methodologies for Offshore Wind Turbine Facilities

The project developed preliminary guideline Integrity Management (IM) procedures for offshore wind turbine facilities appropriate for use in US waters. These procedures include guidance on frequency and method of inspection and address the platform structure, turbine tower, turbine and housing, and turbine blades.

TAP-618-Comparative Study of Offshore Wind Turbine Generators (OWTG) Standards

The objective of this project was to conduct an engineering study that addressed the requirements for standards that are suitable for the design of OWTGs in U.S. federal waters. This study reviewed the applicability and merits of at least two sets of standards that are relevant to offshore wind power development. These standards were the API recommended practice that is currently used for the design and regulatory review of structures used for oil and gas development in the U.S.

OSRR-636-Characteristics, Behavior and Response Effectiveness of Spilled Dielectric Insulating Oil in the Marine Environment

Planned wind projects on the U.S. Outer Continental Shelf could consist of wind turbine generators connected to a centralized electrical service platform (ESP). The ESP could contain approximately 40,000 gallons of dielectric insulating oil and approximately 2,000 gallons of assorted oil-based fluids (diesel fuel, lubricating oils, etc.) stored on site for facility maintenance. In addition, each wind turbines could have several hundred gallons of lubricating fluid.
