Insurers Should Control Ship Classification System: Broker

Insurers should control the ship safety classification process in the light of weaknesses exposed by the Erika’s loss, a senior tanker broker said. Insurance companies should hold the mandate over who inspected vessels’ structural conditions and passed them as safe, an official at Marinav Shipping and Trading said. Since insurers pay out the claim, it is therefore in their best interest to ensure that the vessel is maintained so that risk is minimized, the broker said.
