Civils works for new CMRU plant at Total SGP

Costain was awarded a contract for building the Condensed Mercury Removal Unit (CMRU) at the Shetland Gas Plant, commisioned by Total E&P UK.

EMN Plant were sub-contracted civil extensive services for the construction of the pile cap foundations for the modules of the new plant, including:

• Excavations
• Reinforcment
• Formwork
• Concrete placement
• Cable tracks

Due to the large number of cables, a vaccum excavator was brought in to reduce the amount of manual handling. A large number of foundations were pre-cast at EMNs Scatsta Quarry to minimise the amount of work onsite.

All work was controlled by the site ISSOW permit to work system.

Challenges onsite included deep excavations adjacent to existing structures and so a shoring system and temporary works design was used to minimise the risk.

Concrete was supplied from EMN's BSI accredited batching plant at the Scatsta Quarry.
