    High-Temperature Gas Reservoir Analysis - Germany

    Project Overview

    Arcus Engineering carried out finite element structural analysis and connection verification for an industrial gas reservoir operating under a combination of elevated temperature and internal pressure. The project required the structural response of 16Mo3 / 1.5415 material to be assessed at 520°C under an internal pressure of +110 mbar.


    Project Challenge

    The reservoir's behaviour was influenced by both pressure loading and temperature-dependent material properties.

    The numerical model therefore needed to represent the interaction between:

    • internal pressure
    • elevated operating temperature
    • material behaviour at 520°C
    • structural geometry
    • supports and restraints
    • connection behaviour

    Finite Element Structural Analysis

    Arcus Engineering developed a detailed finite element model of the reservoir structure.

    The analysis was used to evaluate the structural response under the defined operating conditions and verify the relevant components and connections.

    The engineering assessment included:

    • pressure loading of +110 mbar
    • operating temperature of 520°C
    • temperature-adjusted material behaviour
    • global and local structural response
    • connection forces and resistance
    • deformation and stress evaluation

    Connection Verification

    The connections were assessed using forces obtained from the numerical model.

    This ensured that the connection verification reflected the actual load transfer within the analysed structural system and the defined operating conditions.
