When it comes to underwater work, precision, safety, and experience aren’t optional — they’re everything. Nemo Marine Group provides fully certified commercial diving services across Washington State and beyond. Our team combines topside logistics with below-the-surface know-how to deliver clean, code-compliant work under pressure. Whether you need detailed inspections, critical repairs, or time-sensitive recovery — we’ve got the gear, grit, and training to handle it.
Safe, environmentally responsible removal of sunken vessels, debris, and submerged hazards. We handle permitting, containment, rigging, lifting, and disposal.
Underwater welding, underwater BROCO cutting, and topside fabrication support for critical structural repairs and marine steelwork.
Subsurface inspection, cleaning, leak detection, and repair of outfalls, intake lines, and utility conduits using SCUBA or surface-supplied diving.
Targeted material removal and hydro-excavation using diver-operated venturi, airlift, or water jet systems for construction prep, maintenance, or environmental mitigation.
Efficient removal of submerged construction materials, wood, rope, metal, trash, and abandoned gear from marinas, waterways, or job sites.
Remote visual inspections and underwater video using compact Remotely Operated Vehicles for limited-access or deep-water scenarios.
Lost propellers, anchors, tools, electronics, phones, keys — if it sank, we’ll find it. Fast response for private and commercial clients.
Diver-operated manual extraction and containment of invasive aquatic species in lakes, ponds, ocean, and shoreline areas.
Surface Supplied Air Diving for 0'-190' deep or longer-duration tasks where diver communication and safety redundancy are essential.
Lightweight, rapid-deployment diving for inspection, maintenance, and tight-access work where surface-supplied setups are impractical.
Baseline or pre & post-project surveys, video documentation, condition assessments, permitting documentation, and insurance reports.
Nemo Marine Group operates with full OSHA 29 CFR 1910 Subpart T and WAC 296 compliance, is fully insured, bonded, and state-licensed, and is staffed by experienced, DIT-trained commercial divers and supervisors. We bring a mobile, rapid-response team to every job and maintain a clean track record with both private clients and public agencies.
Based in Seattle, we provide commercial diving services throughout Washington State — from the busy ports of Puget Sound to remote inland lakes and rivers. Whether you're managing a marina, tackling a salvage job, or need urgent underwater repairs, our mobile dive team is ready to mobilize fast and get to work.
