ONYX Services utilizes our in-house team of certified divers to perform inspections for pipelines and other assets in marshes, lakes, rivers, and other marine environments.
Underwater Based Services
We serve the oil and gas industries’ needs by providing fully trained and experienced personnel to conduct underwater pipeline inspections, repairs, and maintenance. Our underwater pipeline inspection and repair services are completed by our experienced personnel using the latest equipment. This allows ONYX Services to perform repairs quickly, efficiently and most importantly, in a safe and cost effective manner.
Inspections
Repairs
ONYX Services performs the same repairs in marine environments as we do on land. Media blasting, cutting, coating, and welding are some of the typical pipeline repairs we do every day.
Maintenance
ONYX Services conducts the required maintenance for assets above, on, and underwater. We have a team of certified divers and a fleet of diving and equipment vessels, including barges. This allows us to provide a true turn-key solution.
