Designed to undertake a broad spectrum of underwater tasks, the new vehicle is equipped with larger thrusters for increased through water performance and an improved buoyancy package, facilitating a market-leading 500 kg payload.
The vehicle has a new frame, which is now CNC machined and provides an improved layout for maintenance access and tooling capability. Through-frame lift has increased to 4,000 kg, a rise of over 30% from the EVO II.
The XLX EVO III also includes updated pilot chairs or consoles and FET’s latest control software, ICE Unity, which enables remote operations. Further enhancements are planned by the FET team.
Built at the firm’s UK manufacturing facility at Kirkbymoorside in Yorkshire and supported by the organization’s global network of bases, the ROV is now available to order.

Kevin Taylor, FET’s Vice President Operations – Subsea, said: “For over 50 years, our ROVs have been the standard bearer for heavy-duty subsea operations—and we’re thrilled to now bring to market the next generation.
“As FET’s Work Class ROVs are renowned for, the XLX EVO III is rugged and reliable, but it is also equipped with cutting-edge technology that enables operators to fly with poise, precision, and confidence.
“We are excited to see the results our latest ROV, designed for an optimized performance, will generate for customers now and in the years to come.”
FET is exhibiting at the 2025 Subsea Expo Exhibition & Conference in Aberdeen on February 18–20, with more information on the XLX EVO III available at Stand 55.
