Two John Fredriksen-backed companies are in talks over a reduction in drillship bareboat charters as day rates crash.

Fredriksen-controlled shipowner SFL Corp revealed in a share registration prospectus that it was contacted by the Oslo-listed drilling company on 3 April to start discussions about the leases.

The Oslo-headquartered ship lessor has three drilling unit chartered to Seadrill, where Fredriksen is a 27% shareholder.
