(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 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. |
