DNV proposes ballast-free crude carrier able to cut pollution while reducing costs

摘要

Det Norske Veritas (DNV), the Norwegian classification society, has unveiled an innovative design concept for a very large crude carrier (VLCC) that eliminates the need for ballast tanks. Such a vessel, according to DNV, would prevent the spread of invasive species and reduce air pollution, yet would be cheaper to operate than a conventional tanker.
