COMMISSIONING ENGINEERING / FIELD SCOPE
Hands-on verification of critical data center infrastructure.
This reference is limited to commissioning engineering performed within the FIN04 project environment. The scope covers field-level electrical and mechanical verification, functional checks, measurements and hardware inspection before systems are released toward integrated operation.
RoleCommissioning EngineerEnvironmentMission-critical data center constructionLocationUmmeljoki–Myllykoski, Kouvola, Finland
630 A power feeds
Verification of 630 A electrical feeds, associated hardware and field measurements supporting safe energisation and functional testing.
Chiller systems
Commissioning and functional verification of chiller-related systems and their electrical/control interfaces as part of cooling-system readiness.
Generator systems
Generator commissioning support, hardware checks and verification of interfaces within the resilient standby-power architecture.
Electrical measurements
Field measurements on buses and connected hardware, recorded against commissioning requirements and installation status.
Hardware verification
Inspection and verification of installed equipment, connections and system interfaces before functional and integrated test stages.

PUBLIC PROJECT CONTEXT
A Nordic-scale data center campus.
atNorth currently describes FIN04 as a 45-hectare Myllykoski mega campus in Kouvola with 430 MW power capacity and a path to several hundred additional megawatts. The campus is intended for both colocation and build-to-suit deployments. These figures describe the overall atNorth campus — not Determinova’s commissioning scope.

Scope statement. This case study describes commissioning experience within the Myllykoski FIN04 project environment. It does not state or imply that Determinova Oy designed, supplied, owned, operated or acted as the main contractor for the FIN04 campus. Project-owner and campus-scale information is based on publicly available atNorth material.
