The end of the Middle East summer has come with senior management changes at several of the region’s largest tanker companies.

Former Gulf Navigation chief financial officer Duncan Sawyer has emerged as the new CFO of Dubai-based Al-Iraqia Shipping Services & Oil Trading (AISSOT).

AISSOT had recruited United Arab Chemical Carriers (UACC) CFO and acting CEO Ketil Ostern as its CEO in May.
