Robotic tooling, bolting, and underwater structural rehabilitation.
Remote Subsea Mechanical Maintenance & Tooling
Subsea ROV hydraulic cutting, mechanical flange bolting, and anode welding.
Deep subsea mechanical repairs require specialized tooling packages capable of delivering high hydraulic power with surgical accuracy.
Chow Marine provides turnkey remote maintenance services utilizing custom-engineered ROV skid tools, diamond wire cutters, hydraulic torque wrenches, and subsea stud tensioners.
Our systems perform subsea pipeline cold-cutting, flange gasket replacement, underwater bolt torquing, and sacrificial anode installation without requiring divers in deep or hazardous waters.
All operations are tracked via synchronized high-definition video, multi-angle telemetry sensors, and digital torque-turn logging systems that certify every connection meets API and ASME engineering specifications.
Engineering CAD Tooling Design
Design and simulation of specialized ROV torque skids and reaction brackets for target asset.
Top-Side Testing & Calibration
Full-scale functional testing and pressure testing of all hydraulic actuators and cutters in test tanks.
Subsea Tooling Ingress
Deployment of ROV tooling package to subsea workface with dynamic positioning support.

01
What size pipes can your diamond wire cutters handle subsea?
add
What size pipes can your diamond wire cutters handle subsea?
Our mobile subsea diamond wire cutters can slice through multi-string pipes, concrete-coated lines, and heavy structural tubulars up to 48 inches (1,200mm) in diameter.
02
How do you verify subsea bolt torque accuracy?
add
How do you verify subsea bolt torque accuracy?
Our hydraulic torque wrenches interface with calibrated pressure transducers and digital telemetry that log applied torque in real time, generating an indisputable quality assurance certificate.
03
Can your tooling operate in zero-visibility conditions?
add
Can your tooling operate in zero-visibility conditions?
Yes. By utilizing acoustic positioning, tactile positioning jigs, and dual-frequency 3D sonars, our pilots execute precise mechanical docking and bolting without relying on optical visibility.
