Intro
Tyra SEB (Southeast B) is a fixed jacket satellite platform installed in 2014 at the Danish Tyra field in the North Sea. It provides additional wellhead and manifolding capacity tied into the Tyra complex for gas and condensate, connected via a pipe bridge to adjacent Tyra Southeast installations. Water depth is ~40-m.
Field
The Tyra Field is Denmark’s largest gas condensate field in the North Sea, discovered in 1968 and producing since 1984. It includes multiple platforms processing gas and condensate from Upper Cretaceous and Danian chalk reservoirs. Tyra SEB serves the Tyra Southeast area, complementing central facilities at Tyra East and West.
Facilities
Tyra SEB consists of a four-leg jacket supporting well slot manifolds, test facilities, and auxiliary systems. Its primary role is to collect fluids from drilled wells in the Tyra Southeast reservoir and route them via a pipe bridge into the broader Tyra processing complex. Major processing (separation, dehydration, compression) is conducted on central Tyra processing platforms (e.g., Tyra East/West). Satellite infrastructure integrates lift gas import systems, flow metering, and field utilities such as electrical distribution, chemical injection skids, and safety shutdown systems. The platform’s bridge link enables shared access, control systems, and optimized flow routing. Core stable design features include a rigid jacket with pile foundations, corrosion protection, and subsea tie-ins to central export pipelines that deliver processed gas to Nybro (Denmark) and Den Helder (Netherlands).
