Norwegian tycoon Oystein Stray Spetalen's SD Standard Drilling has made a $9.25m move into the drillship sector by investing in restructured Noble Corp.

Olso-listed Standard Drilling revealed a 1% stake on Monday, after buying 500,000 shares at $18.50 each.

London-based Noble completed its debt restructuring under a court-led Chapter 11 process on 5 February.
