SBM Offshore wanted the initial Fast4Ward semi-submersible design to have a light footprint but also be scalable, writes Kathrine Schmidt.

That meant an initial capacity of 60,000 barrels per day, but with the ability to expand to 120,000 bpd without significant redesign.

Gas processing capacity was initially fixed at 70 million cubic feet per day, but can be modified to go as high as 210 MMcfd.
