Frontline will keep to buying 10 tankers from Trafigura Marine Logistics, declining options to buy four more from the subsidiary of Singaporean trader Trafigura.

John Fredriksen's Frontline last month agreed to buy 10 suezmaxes built this year for 16.1 million common shares at $8 each and a cash amount ranging from $538m to $547m.

Frontline declined an extended option to buy two more suezmaxes by Wednesday, thus ending an option to buy two more by 24 September.
