L10-AD

L10-AD is the original drilling and wellhead platform of the L10-A complex on the Dutch North Sea shelf, installed in 1974. It hosts production wells and bridge connections to adjacent L10-A modules including L10-AP and L10-AR.

Field

Within the L10 gas field, L10-AD accesses Rotliegendes sandstone gas reservoirs. This field has been a major Dutch offshore gas contributor since 1976 and acts as a production and processing hub for the area.

Facilities

L10-AD includes drilled production wells feeding gas into manifold systems. It interfaces with the L10-A complex's processing and riser modules via steel bridges, facilitating centralized separation and export. On-platform systems include wellhead control, flow metering, and safety shutdown (ESD) networks. While it does not host large processing trains, AD is integral to the riser and header configuration feeding into central dehydration, compression, and dehydration facilities located on adjacent platforms. Utilities power instrumentation, communications and safety systems. Export gas flows through the L10 hub into the Noordgastransport pipeline to shore, and integration with satellite ties enables optimized field production.
