The original contract signed on February 26, 2004 with Blackford Dolphin Pte Ltd (Owner), a subsidiary of Fred Olsen Energy ASA, for work to be carried on the Blackford Dolphin was $177m. The expected delivery date was in June 2007. On July 20, 2007, an addendum was agreed upon, which took into account changes up to that point in time by the Owner. The contract value was increased to $239.5m with the delivery date revised to February 2008. Since the addendum, there have been further revisions, including changes to the design of the rig, by the Owner. This has resulted in variation orders and a delay in the completion of the rig. While some variation orders were agreed upon and paid for by the Owner, outstanding and unresolved variation orders remain.
