Turning the tide on ballast water

摘要

ClassNK believes that, in the future, ship designs will become Non-Ballast Water (NOBS) and Minimal Ballast (MIBS) Water Ship designs as an alternative solution to ballast water treatment. The new designs would be attractive because they will significantly reduce shipowners' capital costs. ClassNK has worked together with Japanese shipyards to develop NOBS and MIBS designs. "While our research has succeeded in showing that construction of a NOBS vessel is possible, MIBS is considered to be a much more practical solution".
