Survey & Inspections

Detailed Assessments Above and Below the Waterline

 From aging infrastructure to unknown underwater conditions, clear information is the foundation of safe, successful marine work. Nemo Marine Group offers a full range of survey and inspection services for docks, vessels, waterfront structures, and submerged systems. Whether you're assessing damage, planning construction, or meeting regulatory requirements, our dive-qualified team delivers detailed reports, HD video documentation, and actionable insights — topside and below. 

Our Survey & Inspection Services Include:

Dock, Pier, & Marina Inspections

 Visual and structural assessments of pilings, floatation systems, bracing, hardware, decking, and moorage conditions. 

Floating Structures

 Inspection and documentation of floating homes, houseboats, and boathouses — including flotation, framing, anchoring, and alignment. 

Vessel & Barge & Leak Detection

 Hull surveys, zinc condition checks, fouling assessments, leak detection, and underwater hull inspections for all vessel types.   Air, pressure, or visual testing for hull breaches, pipe leaks, or system seepage — both above and below the waterline. 

Bulkheads, Beaches, & Vegetation

 Shoreline structure assessments, erosion monitoring, and aquatic vegetation mapping for compliance, restoration, or development. 

Non-Destructive Testing (NDT)

 Underwater and topside methods including ultrasonic thickness readings and magnetic particle testing to detect corrosion, cracks, or weld failures without damaging materials. 

ROV Inspections

 Remote Operated Vehicle surveys for limited-access or deep-water areas — capturing HD video with optional sonar or laser scaling. 

HD Video & Audio Documentation

 Professional-grade visual documentation before, during, or after work — ideal for insurance, permitting, or maintenance tracking.

Mechanical & Structural Inspection

 Review of moving parts, anchor points, framework, welds, flotation, and load-bearing components for integrity and operational safety.  

Welding Inspections

 Visual and NDT-based evaluation of underwater and topside welds to identify cracking, undercutting, or porosity. 

Land & Marine Surveying

 Partnership-based surveying for waterfront construction, permitting, and boundary assessments — integrating land and water features.
