Uusimaa, Finland

Job Description

The Instrumentation Engineer is responsible for the design, specification and implementation of process instrumentation in the field and in automation and control rooms.

Due to the high level of automation required for safe and efficient operations in refining, petrochemicals and renewable fuel production facilities, the expertise is generally essential starting from the study phases where the instrumentation engineer participates in scope clarification and feasibility assessments.

During the definition phase, tasks include participation in risk analyses, technical scope definition and the preparation of the basic engineering package.

During execution, tasks include produce the documents and services needed for purchasing, installation, testing, training, commissioning and maintenance.

Instrumentation Engineering has a central role in selecting appropriate field devices, specifying the required instrument and valve types, design of automation and control rooms, cabling, junction boxes, loop diagrams and participates in Factory Acceptance Tests (FAT) and Site Acceptance Tests (SAT) for the control systems.
