The Norwegian offshore safety authority has granted Eni Norge permission to perform manned underwater operations on the Goliat field.
The company asked for permission to allow it to carry out repairs and improvements at the field.
Diving will take place to a maximum depth of 25 metres.
Planned start up at the field is June 2017, with the activities expected to last at least 21 days.
The Goliat field is in the Barents Sea, around 50 kilomteres south-east of Snøhvit.
The field has been developed using a floating production unit (FPSO).
