Atteris performed the Concept Select engineering for the gas export pipeline. Preliminary design included mechanical design, stability and spanning assessments, and preliminary linepipe and coatings material selection. Preliminary route selection was performed taking into consideration geohazards, constructability, bottom roughness, proximity to existing infrastructure and crossings, shore approach, shore crossing and onshore routing options. Various route options were developed and ranked in preparation for offshore survey. Atteris developed the scope of work for survey for the proposed pipeline export route, and cost estimates for the pipeline.
