I think there's a mistake here. This jackup rig was never commissioned as Maersk Goliath cos the owner cancelled the contract just before delivery. She was eventually bought over by Sandvig. West Lambda was only a proposed name for her, but eventually the name West Epsilon was used instead to commission her.
