AX-S System

Contracted under its subsidiary SALT Subsea, Fugro-TSM supports Expro’s groundbreaking subsea well intervention system AX-S™ on a worldwide basis.

AX-S (pronounced 'access') changes the way in which oil and gas companies can access and work on their subsea wells, saving them valuable time and money.

There are approximately 4,000 oil and gas producing subsea wells across the globe and this number is ever increasing. With many now over a decade old, these wells require ‘servicing’ to allow for maximum oil and gas recovery. Current methods generally require the use of a rig to be positioned above the well while this work is carried out, which is a time-consuming, costly activity, with rig costs running at up to $1 million a day.

Expro’s subsea solution is 35metres high and weighs 220 tonnes and is deployed from a monohull vessel. This system can be lowered on to any subsea well in up to 10,000ft of water which covers every subsea well in the world today. This allows Expro’s AX-S system to provide a safer and cheaper alternative to what is currently available.

Fugro-TSM proudly supplies the vessel, Dual Schilling UHD Workclass ROV systems, specialised tooling packages, survey and positioning and overall marine management of the vessel.

The choice of Schilling 4000metre rated UHD ROV systems by Fugro-TSM provides compatibility with the AX-S control systems and sub-assemblies, further enhancing the inbuilt redundancy and reliability of the system..

The AX-S system is currently installed on the Havila Phoenix - view the vessel specifications here.
