Subsea Trees & Wellhead Equipment

​

Legasea specialises in the refurbishment and supply of high-integrity Subsea Trees and Wellhead equipment for the offshore energy sector. Our focus is on providing sustainable, cost-effective alternatives to new build components—delivering certified, field-ready solutions while reducing environmental impact.

​

Refurbished Subsea Trees

​

Subsea trees (also known as Christmas trees) are a critical component in the production phase of subsea oil and gas wells. Legasea offers a wide range of refurbished subsea trees designed to suit diverse field requirements:

​

• Vertical Subsea Trees
  Ideal for shallow to mid-water applications, these configurations simplify installation and maintenance while ensuring reliable flow control.

• Horizontal Subsea Trees
  Commonly used in deepwater developments, horizontal trees allow easier access to the tubing hanger and tree cap, enabling intervention and workover operations.

• HPHT Trees (High Pressure, High Temperature)
  Certified to withstand extreme subsea conditions, our HPHT trees meet stringent industry requirements for safety and durability.

• Dual Bore Trees
  These are suited for complex field architectures, supporting parallel production or injection paths.

• Tree Cap Assemblies & Valve Blocks
  Available as standalone spares or integrated into refurbished systems, all components are pressure-tested and certified before dispatch.

​

Each tree is thoroughly refurbished by our in-house specialists, including complete disassembly, inspection, reassembly with new seals and elastomers, and full functional testing to OEM or client-specific standards.

​

Subsea Wellhead Equipment

​

Subsea wellheads serve as the foundation for safe and efficient offshore drilling and production operations. Our capabilities include:

• Conductor Housings
  Providing the initial structural support for the well, our refurbished conductor housings are inspected for fatigue and integrity before re-use.

• Wellhead Housings & Casing Spools
  These pressure-containing components are reconditioned to ensure structural integrity and compatibility with modern tooling and BOPs.

• Mandrel Hangers & Lockdown Mechanisms
  Refurbished to exact tolerances, ensuring secure casing suspension and reliable sealing.

• Running Tools & Test Stumps
  Fully functional and compatible with industry-standard installation systems, supporting safe deployment and testing offshore.

 

Our subsea wellhead solutions are ready for use in exploration, development, or late-life extension projects. All units are traceable, pressure-tested, and supported with full documentation and certification.
