TABLE 2
Type of facility . . . The CVA must . . .

Make periodic onsite inspections while fabrication is in
progress and must verify the following fabrication
items, as appropriate:
(i) Quality control by lessee and builder;
(ii) Fabrication site facilities;
(iii) Material quality and identification methods;
(iv) Fabrication procedures specified in the approved plan,
and adherence to such procedures;
(v) Welder and welding procedure qualification and
identification;
(vi) Structural tolerances specified and adherence to those
tolerances;
(vii) The nondestructive examination requirements, and
evaluation results of the specified examinations;
(viii) Destructive testing requirements and results;
(ix) Repair procedures;
(x) Installation of corrosion-protection systems and splash-
zone protection;
(xi) Erection procedures to ensure that overstressing of
structural members does not occur;
(xii) Alignment procedures;
(xiii) Dimensional check of the overall structure, including any
turrets, turret-and-hull interfaces, any mooring line and
chain and riser tensioning line segments; and
(xiv) Status of quality-control records at various stages of
fabrication.
Ensure that the requirements of the U.S. Coast Guard floating
for structural integrity and stability, e.g., verification of
center of gravity, etc., have been met. The CVA must also
consider:
(i) Drilling, production, and pipeline risers, and riser tension-
ing systems (at least for the initial fabrication of these
elements);
(ii) Turrets and turret-and-hull interfaces;
(iii) Foundation pilings and templates, and anchoring
systems; and
(iv) Mooring or tethering systems.

(1) For fixed platforms and
non-ship-shaped floating
facilities

(2) For all floating facilities
