Important new measures and procedures to improve the safety of oil tankers and help prevent pollution of the sea from ships were adopted by the International Conference on Tanker Safety and Pollution Prevention. The requirement for segregated ballast tanks (SBTs) was extended to include new crude oil carriers greater than 20,000 dwt and new product tankers greater than 30,000 dwt. The concept of protective location of the SBT, rather than mandatory double bottoms, was adopted. All new crude oil carriers greater than 20,000 dwt must be fitted with an approved crude oil washing (COW) system. Improved drainage and discharge systems for new and existing tankers are required. The requirement for inert gas systems were extended to new and existing tankers greater than or equal to 20,000 dwt and product carriers greater than or equal to 40,000 dwt. New steering gear requirements were formulated. All ships of 1,000-10,000 dwt must be fitted with radar; above 10,000 dwt they must carry 2 independent radar systems. Unscheduled inspections of ships must be carried out if mandatory annual surveys are not undertaken. All tankers greater than 10 yr old must be surveyed annually. The Cargo Ship Safety Construction Certificate survey requirements were extended to include the cargo pumping, piping, and venting arrangements. Specific regulatory proposals to implement these measure will be forthcoming.
