法国船级社GTT无压载船，消除了将有害生物和病原体从一个地区转移至另一个地区的风险。

The classification society Bureau Veritas (BV) has awarded approval in principle to French LNG containment specialist GTT for its ballast-free LNG bunkering and feeder vessel. Therefore, a considerable quantity of ballast water is carried by ships every day. Even when ballast water is treated, there is a risk of transferring harmful aquatic organisms and pathogens from one area to another.
