Underwater Welding & Diving Support

Certified commercial divers for wet welds/cutting, splash-zone repairs, anode installs, and subsea inspections.

Overview

Marine-grade fixes for critical infrastructure

From ports and intakes to river crossings and outfalls, our dive teams execute wet welding and mechanical repairs that restore integrity fast—without full dewatering or shutdowns where safe and permitted.

  • Wet SMAW/GMAW in accordance with AWS D3.6M (Class per project)
  • Splash-zone structural steel, risers, guides, and ladders
  • Mechanical seals, flanges, clamps, and spool piece installs
  • Intake screens, anode systems, and scour protection

Wet Welding & Cutting
  • Carbon steel patch plates and bracket installs
  • Thermal cutting for removal of damaged sections
  • Electrode selection and bead procedure per spec
  • Proof tests and NDT where feasible
Marine Maintenance
  • Intake screen change-outs & debris clearance
  • Riser guides, fender chains, ladders & handrails
  • Anode replacement & continuity testing
  • Scour mats and rock bag placement
Inspection & Survey
  • HD video, photo logs, measurements
  • CCTV/ROV support for lines and outfalls
  • Coating checks & cathodic protection surveys
  • Condition scoring and recommendations

HSE & Controls

Zero-compromise safety governance

  • Dive plans: hazard ID, currents/tides, visibility, entanglement & power isolation
  • Qualified dive supervisor, tender, and standby diver on site
  • Lockout/tagout and electrical bonding for wet welding safety
  • Environmental controls: turbidity limits, spill kits, protected species buffers

Case Study — Emergency Splash-Zone Repair

A storm damaged a riser guide and tore an anode cable at a river intake. We mobilized a two-diver team, installed a welded bracket and new anode, and completed continuity checks—all within a single tide window.

  • Topside isolation & LOTO confirmed prior to wet work
  • Video documentation and weld map delivered next day
  • Owner returned to full operation without dewatering

Underwater welding questions

Safety, feasibility, and documentation.

Wet welds can meet project requirements when procedures and classes per AWS D3.6M are defined. Where higher performance is required, we plan cofferdams or dry habitats.

We schedule around tides/flow windows, add hold-backs, and use tactile guides. If conditions exceed safe limits, we reschedule or change methods to maintain safety.

Dive logs, video/photo records, weld maps, NDT/test results when applicable, and a concise close-out report with recommendations.
