Summary of Key Findings and Recommendations - Structural Integrity of Offshore Wind Turbines - page 128

of the proposed standards and rules in meeting the objectives defined
in the BOEMRE goal-based standards. Although BOEMRE should con-
sider the documentation provided by the developer and the report of
the CVA, the responsibility for approval of the proposed standards and
guidelines and for determination of their conformance with the goal-
based standards should rest solely with the agency.
2. The scope of the BOEMRE third-party review process should include
the following:
- Blades,
- Blade controls (if reliance on active controls is required for load
reduction),
- Tower and structural support,
- Foundation and station keeping,
- Infield cables and connectors,
- Other structures—structural and electrical systems, and
- Export cables.
The third-party review should ensure the following:
Design: The design adheres to good industry practice, the basis of
the design is applicable for the location and stated objectives of the
project, site-specific conditions have been appropriately addressed,
and the identified codes and standards are adhered to.
Fabrication and manufacturing: Quality assurance/quality control
processes are in place to ensure that fabrication and manufacturing
comply with the design and the identified codes and standards.
Installation: All transportation and field installation activities are
performed in a manner ensuring that the facility meets the design
intent.
The third-party reviewer should provide periodic reports to
BOEMRE with regard to the review findings and should note any devi-
ations or concerns.
3. Type certification of a wind turbine may be substituted for portions of
third-party design review if the type certificate is appropriate for site
conditions [e.g., the International Electrotechnical Commission (IEC)
wind class].
4. BOEMRE should retain responsibility for final approval. It is essential
that BOEMRE have staff who are competent to select qualified third
parties (see Task III) and to approve projects.
