The Norwegian Shipowners´ Mutual War Risks Association (DNK) estimates that recent attacks on tanker tonnage in the Middle East have resulted in losses in excess of $100m for the war risks insurance market.

Speaking at a Wilhelmsen Ship Management breakfast seminar in Singapore today, DNK chief executive Svein Ringbakken said that the attacks on tankers have also pushed up the costs of operating tankers in the Middle East Gulf region.
