Dive Inspection

With in-house commercially certified hard-hat divers, our team provides comprehensive dive inspections for a range of environments and conditions.

Our Underwater Inspection Capabilities

We can perform a range of underwater inspection services, from simple timber bulkhead inspections to large-scale marine facility structural evaluation with a licensed P.E. diver. So that we may quickly respond to your needs, we maintain a professional fleet of vehicles and vessels equipped with a full complement of state-of-the-art commercial dive equipment.

We have over 52 years of experience in providing diving services to the marine industry. In addition, we are qualified as an Association of Diving Contractors International underwater inspection company.

  • Ultrasonic Thickness Measurements (H-pile, pipe pile, steel bulkheads, and cells as well as vessel hull plating)

Pro Tips

Most industrial and commercial marine facilities require that those conducting dive operations on their property be certified hardhat divers from an agency like ADCI (Association of Diving Contractors International).

The ASCE (American Society of Civil Engineers) Waterfront Facilities and Inspection Manual No. 130 provides industry-accepted requirements for dive inspections and dive inspection reports.

A certified commercial hardhat diver or dive refers to dive equipment, dive training, and dive procedures that are compliant with standards set by a reputable professional diving association like ADCI (Association of Diving Contractors International).

To conduct a proper ASCE-approved dive inspection, the team usually includes 3-5 certified hardhat divers, a dive supervisor that is a professional engineer, a properly-equipped dive vessel, and a surface-supplied air delivery system.

Divers use underwater cameras to document the inspection process. Ultrasonic Thickness (UT) Instruments are used to measure thickness of steel structures.
