Wintershall has delayed an upcoming decision on concept selection for its Skarfjell project off the coast of Norway in a bid to cut costs further, the firm said Jan. 26.

“We are to choose between a tie-back to Gjoea, a semisubmersible or an FPSO,” project manager Astrid Edvardsen told an industry conference, explaining the different options.

Costs will be cut by some 40 percent from the original estimate, she said, adding that a concept decision is now expected to come in the third or fourth quarter of 2016.

Partners in the two licenses include Capricorn, Edison , DEA, Bayerngas, Explora and Repsol.
