The shift to the bigger "Subsea Corridor" named premises provides space for 60 staff as Jee's profile continues to grow.

Trade association Oil & Gas UK is one supporter, with Jee's lifetime extension projects in the North Sea credited to have extended production life by more than 253 years - estimated to have saved operators more than £114 billion ($A204.9 million).

"The UK Continental Shelf is undoubtedly one of the most mature offshore basins in the world and therefore faces unique challenges," Oil & Gas UK CEO Malcolm Webb said.

"Lifetime extension projects such as those undertaken by Jee are vital to ensure the maximum economic recovery of the UK's remaining oil and gas resource."

Jee Aberdeen office head Dr Jonathan Lindsay said the company was moving away from being a niche pipeline engineering consultancy to becoming a fully integrated service provider.

"Aberdeen, as a subsea centre of excellence, has become the hub of this business activity, from which we market our subsea engineering expertise as we increasingly win engineering projects around the globe," he said.
