The king and queen of Spain visited the Statoil operated Troll A platform today, 8 June, along with Norway's king and queen.
The royal couples headed a delegation of 36 visitors, 18 of whom are from Spain, including Spanish foreign minister Miguel Angel Moratinos.
King Juan Carlos, Queen Sofia, King Harald and Queen Sonja were accompanied by Statoil's chief executive Helge Lund.
Platform manager Karsten Storebø showed them round.
Mr Lund talked to the delegation about Statoil's role as a reliable supplier of gas to Europe, of Troll's significance as the largest gas field on the Norwegian continental shelf and about plans for the future.
The royal couples were then taken down inside the platform shaft to 303 metres below sea level.
This was the first time Statoil hosted a visit to a platform by two royal couples.
Mr Storebø was also platform manager on Troll A the last time King Harald paid a visit in June 1998.
