John Fredriksen’s Seatankers Group has urged bosses at International Seaways to work together to boost the US tanker owner’s performance.

The tycoon’s private investment company Famatown Finance made a presentation on Thursday to “certain members” of the management team, Seatankers said.

This followed up Seatankers’ letter to the board on 10 May after New York-listed Seaways introduced “poison pill” defences in its bylaws to deter a further increase in Fredriksen’s stake.
