Oulun Energia Oy has awarded Pöyry with EPCM-services for the new Laanila OEBIO-project in Oulu, Finland. The construction of the new power plant will be completed in late 2020 and once in operation it will replace Toppila 1 unit. Capacity of the plant will be around 70 MW electricity and around 175 MW district heat with an option to supply steam to clients in the Laanila industrial area. The plant uses forest based biofuels, peat and solid recovered fuel (SRF) as fuels. This supply consists following piping systems:

— DH-condensate system,

— condensate treatment system,

— district heating system,

— DH expansion and pressurising system,

— condensate preheating system,

— closed cooling water system,

— cooling water system,

— raw water system,

— make-up water system,

— fuel oil system,

— compressed air system basic piping engineering result:

—— 6,5 km/160 tons of piping materials, and

—— 85 tons of primary/secondary supports.

Scope of work includes:

— pipes and pipe parts (including for example bends, elbows, reducers, Y-pieces, Tpieces, condensate pockets) material, prefabrication and installation,

— installation of piping related equipment, for example valves, pumps, filters, small vessels, etc,

— primary and secondary supports,

— scaffolding,

— all needed documentation according PED 2014 and EN13480.

The following detail design is included in the suppliers's scope of work:

— final stress analysis and strength calculations, the purchaser will deliver preliminary stress analysis,

— non-standard pieces, calculation and workshop drawings,

— the supplier will make detail design to the Purchaser's PDMS 3D-model on the purchaser's preliminary design,

— detailed engineering includes also updating 3D-model according to purchased equipment, valves, pumps, filters, small vessels, etc.,

— detail isometric and support drawings.

Piping supplier is the fabricator of the piping and shall give CE-marking.
