The study considered an ultra-deepwater field development in 3000 metres of water, using 8 inch nominal pipe rated for 10,000 pounds per square inch pressure — comparable to the most challenging prospects currently being evaluated. It assumed a system of eight self-standing single leg offset risers (SLORs).
Previous analyses by Calash indicate that, when built using steel for risers, a full field development like this “typically carries a project budget of around $2.5
