Tree running tools and legacy well connectors

A TRT and legacy well connector connects to the top of a subsea tree, allowing the tree to be safely installed, recovered and accessed throughout its operational life. It also provides the critical interface between the tree and the equipment required for future intervention activities.

We supply TRTs for both vertical and horizontal subsea tree systems, including mono-bore and dual-bore configurations. Each solution can be configured around the specific tree interface, operating environment and intervention methodology.

This flexible approach supports a wide range of offshore operations, including riser-based intervention, wire-through-water campaigns, slickline and e-line activities. Depending on the project, the TRT or legacy well connector can interface with intervention risers, subsea lubricators and pressure control equipment, providing a reliable connection between existing subsea infrastructure and the equipment required to access the well.

From installation and maintenance through to intervention and eventual well abandonment, our TRT and legacy well connector systems help operators maximise asset value while maintaining flexibility throughout the field lifecycle.

We supply TRT and legacy well connector systems for both vertical and horizontal subsea tree architectures.

For vertical tree applications, we can provide mono-bore and dual-bore connector systems, including interfaces designed to engage with vertical tree entry mandrels. For horizontal tree applications, our TRT solutions incorporate adaptable stinger and connector arrangements engineered around the existing tree configuration.

The modular nature of our systems allows connectors, stingers and crossover arrangements to be tailored to different tree manufacturers, sealing profiles and interface requirements.

This flexibility is particularly valuable across mature fields and multi-field campaigns where operators may encounter several subsea tree designs. Rather than sourcing multiple specialised interfaces, a coordinated adaptable and configurable TRT solution can simplify access across the entire development.
