Diving Services Incorporated

What Diving Services Incorporated does

Diving Services Incorporated (DSI) is a privately held commercial diving services company headquartered in Foster, Rhode Island, with operations covering the New England and East Coast markets. The firm has been operating for over ten years and provides fourteen specialized underwater services, including marine construction, underwater welding and cutting, potable water tank cleaning and inspection, underwater concrete placement, crack and leak repair, remote pipe inspection, in-house fabrication, P.E. diver assessments, underwater bridge inspection, dam inspections, hydrographic surveys, side scan sonar, NDT testing, and 3D modeling and CAD design. Service delivery combines commercial hard hat diving with real-time video, pipe inspection ROVs, Pierpoint P350 Flexitrac inspection cameras, side scan sonar, and hydrographic survey equipment with DGPS sub-meter accuracy.

DSI's technical stack spans field sensors, fabrication, and engineering analysis. On the inspection side, the firm deploys non-destructive testing (ultrasonic, magnetic particle, liquid penetrant), specialized ROVs, and sonar-based survey tools. For engineering deliverables, DSI produces 3D models with finite element analysis using Autodesk development software. The company has in-house fabrication capabilities including CNC plasma cutting and welding machines, allowing rapid production of custom dive tooling and structural components. Compliance is maintained across AWWA C652-92, AWWA regulations, NSF 61 for potable water contact, ADCI standards, NBIS (National Bridge Inspection Standards), and PONTIS rating systems — collectively covering the dominant procurement requirements for bridge, dam, and water infrastructure underwater work.

The business model is project-based professional services delivered on a direct or sub-contracting basis with quote-based pricing. Primary customer segments are government and municipal agencies and engineering firms; secondary segments include construction contractors and private owners/facilities operators. The firm is positioned as a specialized technical contractor for inspection, maintenance, and repair of underwater infrastructure, with the P.E. diver credential combination serving as a primary differentiator in the regional market.
