In the latter half of 1980's, YP40 steels by TMCP were newly developed and have been utilized for various types of large vessels. In this paper, application assessment on the YP40 steels in the NK-classed large vessels is discussed. Then the assessment comes to the following conclusions: (1) The YP40 steels have been widely applied to the NK-classed large vessels. In particular, the YP40 steels-applied bulk carriers (number of ships-based) reaches as far as 50%. (2) Heeding points on design and workmanship in way of hatch opening corner and hatch side coaming end are obtained from the damage review of the large bulk carriers applying the YP40 steels. (3) It appears that no unusual damages due to the application of the YP40 steels occur in the large container carriers and oil carriers.
