Gross registered tonnage 1993 1994 Over 10,000 4,341 4,412 Over 20,000 2,435 2,513 Over 50,000 1,221 1,284 Over 100,000 140 133 Figures for net registered tonnage—NRT—and the number of double hull oil tankers are not available. As the regulations requiring new oil tankers to be fitted with double hulls, or similar structures, have only recently been introduced, the majority of existing oil tankers have single hulls.
