Production Platform- Gas
The Leman Alpha is a Shell operated platform, lying approximately 43 miles (69 km) east of Lowestoft England, in block 49/26 of the UKCS Southern North Sea (SNS). It sits in 121ft (37 meters) of water.
The Leman field is jointly owned by ExxonMobil.
Discovered in 1966, the Leman field takes its name from its location- the Leman bank. The Leman Alpha started production in August 1968 and being. Being the only platform in its field to be manned, the Leman Alpha takes all produced gas and fluids from its outlying satellites before sending them ashore via pipeline to Bacton Gas Terminal.
The Leman Alpha's satellites include the Leman Bravo (previously manned) Leman Charlie (previously manned), Leman Delta (previously manned), Leman Echo, Leman Foxtrot, Leman Golf.
The Leman Alpha also imports and processes produce from the Corvette, Brigantine (BG and BR), Caravel and Shamrock platforms.
After recent upgrade projects, production is planned to continue to at least 2028.
Leman Alpha is of a steel jacket design.
The Leman Alpha like all platforms in the field produces gas product only. This does include condensate. All produce from its satellites and its own wells is processed on board Alpha, before being exported via subsea pipeline back to Bacton Gas Terminal on the Norfolk coast.
