FB Group recently supplied a Glycol Regeneration Unit (TEG) to one of our customers. The Glycol Unit will be installed on a newly built unmanned offshore gas production platform.
The unit complies with the highest environmental emission regulations and contains electric operated valves and sophisticated controls.
Complete design and fabrication was performed ‘in-house’ by FB Group.
After being tested the packaged unit was transported to the platform construction yard.
Built for unmanned offshore operation
Unmanned platforms place particular demands on process equipment, since the unit has to run reliably for long periods without operators present to intervene. To support this mode of operation, the Glycol Regeneration Unit was fitted with electric operated valves and an integrated control system, rather than relying on manual intervention or pneumatic actuation that depends on a dedicated instrument air supply. This allows the unit to be monitored and controlled remotely, so glycol regeneration continues automatically as part of the platform’s unattended operating philosophy.
Why glycol regeneration matters
Glycol regeneration keeps the platform’s gas dehydration system working continuously. As triethylene glycol absorbs water from the produced natural gas, it becomes saturated and needs to be reconditioned before it can be recirculated. This unit reboils and strips the glycol to restore its water absorbing capacity, so the dehydration process keeps meeting pipeline water content specifications without interruption, even on a platform with no permanent crew on board.
In-house design and fabrication
Performing the complete design and fabrication in-house gave FB Group full control over quality, scheduling and interface management throughout the project. Engineering, procurement and workshop fabrication were coordinated under one roof, which reduced handover risk between disciplines and made it easier to adapt the design to the specific requirements of an unmanned platform as the project progressed.
Testing and transport
Before leaving the workshop, the packaged unit underwent testing to confirm that the process, control and safety systems performed as designed. Only after passing these checks was the unit transported to the platform construction yard, ready for final integration onto the offshore structure. This approach limits the amount of commissioning work that has to be carried out offshore, which is particularly valuable for platforms designed to operate without permanent personnel.
