Our highly experienced structural engineering and design team provide a multi-faceted service to our clients from consultation and conceptual studies, through FEED and detailed design to complex engineering analysis including Finite Element Analysis (FEA) and “react” scopes of work.

Our experience providing detailed design for clients covers a wide range of greenfield and brownfield projects. Examples include detail design of Living Quarters (LQ), support grillages, repair clamps, subsea support clamps, caisson & conductor engineering, equipment supports and ROV launch systems. Our experienced design team is capable of producing detailed engineering drawings on AutoCAD to tight schedules with the necessary quality control applied.

    Enabling Efficient Design

    We encourage collaboration between all engineers & designers. Our aim is to achieve safe, practical solutions using an efficient combination of detail engineering and analysis.

    Having these capabilities in-house minimises interfaces and can even remove all interfaces between anomaly assessment, mitigation and detailed design of remediation or repair.
