30 C.F.R. § 250.917 What are the CVA's primary duties during the fabrication phase?
Title 30 - Mineral Resources
(a) The CVA must use good engineering judgement and practices in conducting an independent assessment of the fabrication activities. The CVA must monitor the fabrication of the platform or major modification to ensure that it has been built according to the approved design and the fabrication plan. If the CVA finds that fabrication procedures are changed or design specifications are modified, the CVA must inform you. If you accept the modifications, then the CVA must so inform the Regional Supervisor. (b) Primary duties of the CVA during the fabrication phase include the following: (c) Reports. The CVA must submit interim reports to the Regional Supervisor and to you, as appropriate. The CVA must prepare a final report covering the adequacy of the entire fabrication phase. The final report need not cover aspects of the fabrication already included in interim reports. The CVA must submit one copy of the final report to the Regional Supervisor within 90 days after completion of the fabrication phase but before the beginning of the installation phase. In the final report the CVA must: (1) Give details of how, by whom, and when the independent monitoring activities were conducted; (2) Describe the CVA's activities during the verification process; (3) Summarize the CVA's findings; (4) Confirm or deny compliance with the design specifications and the approved fabrication plan; (5) Make a recommendation to accept or reject the fabrication; and (6) Provide any additional comments that the CVA deems necessary.

§ 250.917 What are the CVA's primary duties during the fabrication phase?
------------------------------------------------------------------------ Type of facility . . . The CVA must . . .------------------------------------------------------------------------(1) For all fixed platforms and non- Make periodic onsite inspections ship-shaped floating facilities. 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 tolerences 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.------------------------------------------------------------------------
