The International Maritime Organization updated the Salvage Convention protocols in recent years to address environmental liabilities, requiring salvors to consider the prevention of oil pollution and hazardous material release during operations. These changes directly impact insurance premiums, with P&I clubs now factoring wreck removal costs into coverage models, pushing annual premiums for large container ships above 100,000 dollars IMO.
