    Fabric Maintenance of Pipework on FPSO

    Overview

    iasgroup was required to perform a blast, paint and remediation scope on a FPSO in the north west of Western Australia. The FPSO produces around 20,000 - 30,000 barrels of liquids per day and therefore production uptime, asset integrity and safety were of the highest importance to the client.

    The pipework on the asset is exposed to high corrosion rates due to its operating environment. The client required significant life extension to this critical part of the FPSO by firstly working with the iasgroup to develop a condition assessment and repair strategy, and secondly engaging the iasgroup to deliver a prioritised and optimal abrasive blasting, coating and remediation campaign.

    Scope

    The project had the following specifications:

    Structure FPSO
    Application Type Blast, paint and reinstatement
    Operating Environment Offshore
    Quantity 1 - entire produced water system
    Remediation Length 32 linear meters
    Pipe Diameter Majority 300 NB
    Method

    Low Dust Dry Abrasive Blasting - SpongeJetTM

    Protective Coating

    FRP Wrap Repairs

    Solution
