  "term": "Subsea isolation valve",
  "field": "Oil and gas",
  "definition": "A large valve, or assembly of valves, installed on a subsea pipeline or flowline to stop the flow of hydrocarbons in an emergency. Actuated remotely from a control platform or vessel, it provides a means to isolate a section of pipeline, a manifold, or a well from the rest of the production system. These valves are a key safety barrier for preventing or limiting the scale of an oil or gas release on the seabed.",
