Qualifications Needed by Certified Verification Agents - Structural Integrity of Offshore Wind Turbines - page 120

c. Directed by a registered professional engineer (or international
equivalent). The intent of this requirement is to establish a baseline
level of experience and qualifications for the CVA lead. It is the opin-
ion of the committee that this goal can be achieved through both U.S.
and non-U.S. professional registrations.
2. A CVA for the design stage must have expertise in
a. Identification, specification, and implementation of design limit
states;
b. Fatigue and strength design approaches, including the effects of
coupled wind-wave dynamics;
c. Determination of the adequacy of proposed design environmental
conditions for the site;
d. Evaluation of foundation design;
e. Evaluation of interaction between the foundation and the turbine
system;
f. Determination of the adequacy of the geotechnical assessment; and
g. Performance of design calculations similar to those provided in the
design reports.

This is not a requirement that independent calculations be performed
but that the CVA be able to perform them as necessary.

3. A CVA for the fabrication stage will need expertise in
a. Fabricator quality control,
b. Material quality evaluation,
c. Welder qualifications,
d. Nondestructive testing,
e. Destructive testing (e.g., full-scale blade tests), and
f. Blade materials and fabrication.
4. A CVA for the installation stage will need expertise in
a. Evaluation of installation plans and procedures;
b. Witnessing of installation operations including loadout, towing,
launching, uprighting, submergence, and so forth;
c. Marine operations;
d. Subsea cabling activities including trenching, burial, and connections;
e. Offshore construction activities; and
f. Installation equipment.
