Avspillingsmodulen

Avspillingsmodulen, or spill handling module, is a term used in Norwegian technical contexts to describe a component designed to manage the release or overflow of liquid in a system. The exact role varies by domain, but it generally refers to the part of a control system that detects high liquid levels or pressure, computes the amount to release, and actuates discharge paths in a controlled manner to prevent damage or environmental release.

Core functions include monitoring sensors, performing spill volume calculations, initiating alarms, controlling valves or pumps, implementing safety interlocks, and logging events for traceability. It often operates within a broader process control architecture (PLC/SCADA/DCS) and interoperates with data historians, alarm management, and maintenance interfaces.

Architecture and design typically involve a modular setup with input interfaces for level, flow, and pressure sensors; logic modules; output actuators; and communication links via standards such as OPC UA or Modbus. The module includes fail-safe modes, redundancy, and testing capabilities. In some implementations, it can simulate spills for training or planning purposes.

Applications span municipal stormwater overflow management, wastewater treatment overflow routing, chemical or oil and gas processing, cooling systems, and industrial safety relief systems. Design considerations emphasize reliability, fail-safety, regulatory compliance, sensor calibration, maintenance and audits, cybersecurity, and access controls.

Terminology related to avspillingsmodulen varies by sector, and the concept overlaps with spill containment, discharge management, and overflow routing. See also overflow, discharge control, SCADA, and PLC for related topics.
