John Fredriksen is in talks to buy four drillship newbuildings cancelled on Monday by his publicly-listed Seadrill.

A Seadrill court filing in the US cited by Bloomberg reveals that Fredriksen is negotiating a deal to acquire the vessels through an affiliate of his private investment company Hemen Holding.

This company was not named, but Fredriksen formed Northern Drilling last year to buy a semi-submersible rig that was cancelled by Seadrill at Hyundai Heavy Industries.
