A T/C provided that Charterers were to redeliver the Vessel with “about” the same quantities of bunkers as on delivery and “should…difference….exceed 5%, Charterers shall compensate Owners losses …”.Charterers redelivered with some 13% less FO and 50% less MGO than on delivery. The Owners claimed as damages the market rates for the entire shortfalls, contending that the 5% allowance was not applicable if exceeded. The Tribunal held that within 5% gave rise to no breach and only awarded damages for the net shortfalls.
