Code of Federal Regulations Title 30. Mineral Resources § 30.250.917 What are the CVA's primary duties during the fabrication phase?

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

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.

(2) For all floating facilities,

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 tensioning 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.
