"This is the single-largest subsea contract that we've won in the UK," Alan Brunnen, head of Aker Solutions' subsea business, said in a statement on Monday.
"It further consolidates our position in the UK, which is our biggest hub outside of Norway."
The Norwegian company said it was gearing up for a 2014 delivery of 25 subsea trees and six template manifolds, along with associated controls, wellheads and tie-in equipment.
"The order includes subsea technologies that are new to the UK market," Aker Solutions elaborated, while declining to name its British client.
The company employs approximately 28,000 people in more than 30 countries.
