Coast Guard Elements

Deepwater covers all items under the jurisdiction of Coast Guard regulations on the OCS (33 CFR 140.103, Title 33, Subchapter N, Outer Continental Shelf Activities, Parts 140-147). Deepwater ensures owners & operators comply with required documentation (form CG-5432).

Riser Survey

Riser inspection includes monitoring CP readings at both ends and close attention to continuity readings.

Transformer Rectifiers

When a structure has impressed current cathodic protection installed, Deepwater's inspectors take special care of the rectifier portion. Monitoring the output and maintenance of the rectifier is critical for the corrosion control system. Each is tracked as a separate asset in our online database,

Vessel Interiors

As part of an extended level 1 program, we include cathodic protection testing of the process vessel interiors.
