John Fredriksen’s Seatankers Management is said to have extended a VLCC newbuilding series at Dalian Shipbuilding Industry Co (DSIC) with the addition of two extra vessels.

Shipbuilding sources said the large crude carriers were options the Norwegian shipowner held at the yard.

Exercising them brings Seatankers’ tally of 307,000-dwt vessels on order at DSIC to eight.
