Caravel QR

The Caravel QR is a normally unmanned installation (NUI) in the Caravel gas field, UK Southern North Sea, consisting of a minimal facilities monotower structure installed to host wellheads and basic manifolding. It facilitates gas production tied back to the Leman Alpha processing hub via subsea pipeline.

Field

The Caravel gas field lies in Block 49/20b in the Southern North Sea, producing Rotliegendes sandstone gas with modest volumes. It was developed with Caravel QR and associated small NUIs tied into larger processing infrastructure at Leman Alpha.

Facilities

Caravel QR sits on a single-leg monotower jacket with well conductors terminating at Xmas trees and basic manifolds. There is no significant hydrocarbon processing; produced fluids are routed via a subsea pipeline (typically 36.6-km) to the Leman Alpha hub for liquids removal, compression, dehydration and export to shore. Onboard utility systems are minimal, limited to remote-operated shutdown valves, chemical injection for hydrate and corrosion control, and power for control instrumentation. Safety systems include fire & gas detection and ESD logic tied via umbilicals to Leman Alpha remote control. The installation is unmanned, with access for maintenance via crew transfer and helicopter landing scheduled as needed. The simplified design reflects small-field economics with reliance on central processing at Leman Alpha, including compression and metering facilities.
