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.
