EPCM delivery for Shotton Biomass CHP Plant, UK

EPCM Services for 20 MWe Shotton BFB CHP Plant at UPM’s Paper Mill

When UPM-Kymmene (UK) Limited (“UPM”) decided to convert the Shotton Paper Mill to process 100% recycled newsprint they required a solution to recover the resulting sludge through combustion.

The concept chosen by UPM was a bubbling fluidised bed (BFB) design, supplied by Valmet, to provide a third of the power required on site and 90% of the process steam.
AFRY were commissioned to carry out the complete basic, detailed and implementation engineering of the plant including procurement services.

AFRY’s services included:

  • the initial conceptual design and feasibility study;
  • technical support with financial modelling; and
  • full engineering services for the EPCM multi-contract implementation.

The EPCM engineering services included the:

  • specification of individual plant packages (i.e. fuel handling, boiler, turbine);
  • interface engineering between the packages; and
  • detailed engineering of the balance of plant systems (i.e. electrical system, automation system, and piping).
