This is a major innovation for Total, which regards this aspect as “the main challenge involved in the project”.

The STAD will provide storage, power, pumps and accommodation. For drilling operations on the TLP Total has devised a bespoke derrick equipment set mounted on its upper deck. Another challenge is the mooring of a pairing like this. The two units are 29 metres apart, linked by a gangway and a “high line” wire rope to transfer pipes.
