This happened many years ago with a 212.
The "other" rig was very close to the Calabar field.
Visibility was very poor and the other rig was the sister rig to the one they wanted to fly to, which was also nearby.
I think once on the deck the crew noticed the name....woops!
They discussed the mistake with the rig and departed after all were happy.
If I remember correctly the crew immediately notified Lagos BHL of the mistake.
