Intro
G16a-B is a fixed normally unmanned gas production satellite platform in Block G16a of the Dutch North Sea, commissioned in 2011. It produces natural gas and provides initial water separation before routing production via pipeline to the downstream G17d-AP platform for further treatment. The installation is part of the G16a cluster of offshore gas infrastructure.
Field
The G16a gas area is a shallow-water conventional gas province in the Dutch sector, with Rotliegendes sandstones targeted for natural gas. Development of the G16a blocks uses fixed platforms like G16a-B tied into a wider network of adjacent facilities to optimize recovery and export.
Facilities
G16a-B’s topsides include production wellheads with associated water separation to remove free water before exporting gas. Produced gas is metered and routed through a 14- main pipeline and a 2- piggy-back line to the G17d-AP platform for further processing and export. The jacket and topside were fabricated for unmanned operation with remote control, safety shutdown, fire/gas detection, and communications systems. Electrical power is supplied by local generator sets for control and essential systems. Utilities include instrument air, cooling, and emergency systems. The design emphasizes robust compression and separation interfaces to across the subsea pipeline network, with periodic vessel-based maintenance to ensure structural and pipeline integrity.
