Never been in war-canoe building AFAIK. The KBR contribution to CVF was mainly out of DML, who have some good lads, but not entirely au fait with building big ships (or any ships if we're honest).
What is more interesting is that Drayson appears to be using the Halliburton buyout as a lever to remove one of the obstacles to his cherished Maritime Industrial Strategy, if the bit about being forced to sell their stake in Guzz is gen dit. This paves the way for Subco which is fair enough, makes sense all round. Trouble is that Shipco makes as much sense as a chocolate fireguard.........
