Subsea XMT from Aker Solutions ASA - modular tree for harsh North Sea fields

Subsea XMT from Aker Solutions ASA sits invisible on the seabed, a yellow steel frame slowly disappearing into green North Sea water as ROV lights flicker across its valves. For offshore engineers, this production tree is the quiet core of a whole field’s cash flow.

What the Subsea XMT is built for

The Subsea XMT is Aker Solutions’ modular subsea production tree for oil and gas wells in water depths typically down to 3,000 meters and working pressures around 10,000 psi. It is designed for harsh environments like the Norwegian Continental Shelf and deepwater projects globally.

The system sits on the wellhead and routes production fluids, injection streams and control signals, while allowing safe well access for interventions. Operators can configure valves, choke modules and control interfaces to match each field’s specific pressure, temperature and flow requirements.

Modularity and standardization offshore

Product lead Håkon Fure at Aker Solutions often highlights how the XMT uses a standardized core frame with swappable modules rather than one-off bespoke designs. That means fewer drawings, shorter engineering cycles and simpler inventory planning for operators.

Instead of ordering an entirely new tree design for each tie-back, a project team can pick from a catalog of valve blocks, chemical injection modules and control pods that bolt into the same frame. That reduces interfaces, which is precisely where many subsea delays and leaks originate.

How it feels in operation

On a drillship control chair, the XMT feels present only through screens and joystick resistance. When an engineer like Maria Jensen nudges a choke setting, the flow graph responds in a smooth slope instead of a jagged spike, a small but critical sign of predictable hydraulics.

Field crews tend to appreciate the clean layout of lifting points and ROV panels. Fewer protruding structures mean less chance of snagging an umbilical or tool, which matters when you are maneuvering 50 tons of steel in low visibility 1,500 meters below the surface.

Strengths and where it compromises

The XMT’s main strength is its balance between modularity and qualification depth. By reusing core components already qualified for high pressure and low temperature, Aker Solutions can offer quicker delivery than fully custom trees yet still satisfy strict NORSOK and API requirements.

The trade-off is that ultra-niche field concepts may still need additional engineering or deviations, for example for extreme high-temperature wells or unconventional wellhead geometries. In those cases, some operators may turn to more customized tree systems despite longer lead times.

Digital integration and life-of-field

The tree is designed to work with Aker Solutions’ own control systems and monitoring tools, feeding pressure, temperature and valve position data into topside and cloud analytics setups. That enables predictive maintenance approaches instead of purely time-based interventions.

For an operator, the value shows when a trending vibration signal on a choke lets them schedule an ROV campaign in a summer weather window, instead of sending a vessel in winter after a sudden failure. That kind of planning often saves more than the tree’s incremental cost.

Where Aker Solutions positions the XMT

Aker Solutions uses the Subsea XMT primarily in tie-back developments and new greenfield projects on the Norwegian Continental Shelf, the UK North Sea and selected deepwater plays elsewhere. The product sits alongside manifolds, umbilicals and engineering services in the subsea portfolio.

For investors, subsea trees are a visible indicator of subsea project sanctioning, since each new well typically requires its own XMT. Order intake here often foreshadows engineering and installation work that will hit revenue over several years.
