Underwater Inspections

Sterling delivers underwater inspections using purpose-built ROV (Remotely Operated Vehicle) technology, providing visual condition assessment of bridge piers, culverts, marine structures, and subsurface infrastructure without the costs and safety risks associated with dive teams. Our ROV capability enables inspections in zero-visibility environments, confined spaces, and underwater conditions where traditional diver-based methods are impractical or prohibited.

We deploy ROVs equipped with high-definition cameras and sonar for scour assessment around bridge foundations, structural condition surveys of underwater elements, riverbed substrate analysis, and confined space entry for culverts and drainage infrastructure. ROV inspections provide video documentation, still imagery, and dimensional measurements supporting structural assessments, remediation design, and regulatory compliance reporting.

Sterling's underwater inspection capability integrates with hydrographic surveying — combining ROV visual inspection with bathymetric mapping to provide comprehensive condition intelligence for marine and subsurface assets. This approach supports infrastructure owners in managing underwater deterioration, validating scour protection performance, and planning remediation works based on actual observed conditions rather than assumptions.
