New York-listed Diamond S Shipping has filled out its complement of directors who will join the board of an enlarged International Seaways once an all-cash merger is completed later this year.

Private equity executive Nadim Qureshi and independent director Alexandra Kate Blankenship – a long-time fixture in the John Fredriksen group – are slated to land on the Seaways board, where they will join current Diamond S chief executive Craig H Stevenson Jr.
