Aisus Offshore, based in Bridge of Don, carried out a workscope on Repsol’s Yme oilfield about 60 miles from the Norwegian coast.
Aisus, part of energy services group Valor, hopes it will pave the way for other overseas work and an increase in headcount.
Andrew Mitchell, managing director, said: “Not only is this (Repsol contract) the largest project completed by Aisus to date, but it highlights that our expertise can be harnessed regardless of location.
“Increased demand for our services internationally proves that our reputation for operational excellence is growing.
“This contract win and successful completion has been a major boost for the business, helping us achieve record-breaking results whilst gaining market-entry into the Norwegian continental shelf.”
The value of Aisus’ deal with Repsol was undisclosed.
The Yme field was initially developed by Statoil from 1996 to 2001 and is now being redeveloped by Repsol Norge.
