“We haven’t done any benchmarking, but for a newbuild like this — with all the facilities available at a typical yard — it should be cheaper than purpose-building (a GPP with CCS) somewhere on land ... The hull doesn’t drive costs much, and inshore, we might change to a different hull to be cheaper to construct.”
