Under Water Cutting Underwater Cutting with Onyx Engineering Precision Below the Surface. Performance Above Expectations. At Onyx Engineering, we bring the same level of expertise and precision to underwater environments as we do on land. Our underwater cutting services are designed to support complex marine, industrial, and infrastructure projects that demand accuracy, safety, and reliability — even in the most challenging conditions. Why Choose Onyx for Underwater Cutting? Specialized Expertise Our team includes trained commercial divers and certified technicians who understand the unique demands of submerged operations — from tidal currents to limited visibility and pressure differentials. Advanced Cutting Technologies We utilize a range of techniques including oxy-arc cutting, hydraulic shears, diamond wire sawing, and abrasive waterjet systems — selected based on material, depth, and site conditions. Applications Across Industries From cutting submerged pipelines and pilings to dismantling offshore platforms, ship components, and dock structures, our services support construction, decommissioning, and emergency response needs. Safety-First Approach We operate under strict safety protocols, ensuring all underwater work meets both regulatory standards and Onyx’s internal benchmarks for operational excellence. Environmental Responsibility Minimizing disruption to marine ecosystems is a priority. We implement best practices to control debris, turbidity, and contamination throughout the cutting process.
