Jee Ltd
Independent subsea engineering company that also runs professional training in subsea systems, pipelines, risers, umbilicals and flexibles.
Jee provides engineering and training services across the oil and gas, renewable energy, and marine sectors, with a strong emphasis on subsea engineering and pipeline-related work. Its expertise covers the full asset lifecycle, from concept design and feasibility through FEED, detailed design, construction support, operations and maintenance, integrity management, lifetime extension, and decommissioning. That work spans offshore and onshore projects alike, and the company delivers bespoke engineering solutions rather than off-the-shelf products. A major part of the business sits in subsea and pipeline engineering. Services here take in pipeline assessment, pipeline inspection, pipeline design, asset integrity management, pigging, flow assurance, decommissioning, project management, and support for subsea intervention. The company works on subsea pipelines, flexibles and risers, subsea structures, sea-fastenings, corrosion defect assessment, freespan assessment, dynamic riser analysis, and cost and schedule estimation for subsea projects. It provides engineering support for offshore loading systems and for pipeline route definition, along with remedial and lifetime-extension work on existing assets. Jee serves the energy transition market too. It works on hydrogen, offshore wind, cables, and carbon capture, usage and storage, with services that cover the lifecycle of renewable projects from feasibility studies and design through to installation and maintenance. In the hydrogen area, Jee offers pipeline repurposing, pipeline design, pipeline inspection, decommissioning advice, and consultation on safety and regulatory compliance. It helps assess whether existing pipelines suit hydrogen applications, and it supports storage, transport, and distribution-related considerations. Training forms another core part of the offering. The company runs public and in-company training for delegates in the oil and gas and renewable energy sectors, with courses covering pipeline design, integrity management, offshore wind, hydrogen, carbon capture, and related technical topics. That training stays practical and interactive, aimed at graduates through to experienced professionals. Jee combines technical engineering consultancy with specialist training, and it distinguishes itself through its focus on subsea infrastructure, whole-life asset support, and energy transition subjects.
