From record-breaking high-temperature drilling motors for oil & gas and geothermal wells, to decontamination tools for decommissioning subsea oil storage tanks, to subsea trenchers and excavators for the offshore wind industry, in the last 20 years our research engineering team has produced world-leading technologies in a broad range of applications.
With a fully equipped workshop, in-house machine shop, and extensive test facilities, we control all aspects of new technology development through design, prototyping, testing and final production.
Previous and current projects include:
Rotech RS Excavator Range
The current state-of-the-art in subsea Controlled Flow Excavation and Trenching.
Rotech Aquaflow / 'T-shaped' Excavators
The original Rotech Subsea mass flow excavator fleet.
Aquaflow Application Software
A software package for the prediction of subsea excavator performance and progress rates.
The world’s first all-metal hydraulic motor for cleaning geothermal and oil & gas wells at temperatures up to 260°C (500°F). Licensed to Weatherford International Inc.
An ultra-short drilling turbine for use in hard-rock and high-temperature applications.
The Rotech Tidal Turbine, a research and development project which led to the design of a 1MW tidal energy electricity generator.
Rotech Downhole Gearbox
A high-temperature gearbox for downhole drilling and power generation tools.
The Rotech Gravity Base Decommissioning Tool, a tool for remotely cleaning out contaminated tanks at the base of large gravity-base structures or other subsea vessels.
A software package for the modelling of down-hole motor performance with compressible and incompressible fluids.
