To establish the change in risk profile a comparison of the original design metocean criteria with the revised metocean criteria was undertaken and a gap analysis performed. Where gaps existed within the current assessment matrix a reassessment was performed by Atteris. These assessments included stability, fatigue and extreme loading conditions for each of the asset components. When undertaking reassessments Atteris noted any synergies between previous assessments, this allowed Atteris to eliminate the requirement for additional detailed finite element analysis.
As a consequence the overall delivery schedule was shortened considerably resulting in a reduced overall cost to the client.
