ASSESSMENT AND CALCULATION METHOD OF COATING DAMAGED  AREAS  FOR  BALLAST  TANKS OF SHIPS



Foreword


MSC.215(82) prescribes the preparation of steel substrates before application of paints and related products for ballast tanks of ships:
o        Sa2½ with abrasive blasting during block coating;
o        surface treatment of  butts (after erection) shall be carried out by means of tool grinding,
o        small damages up to 2% of total area: St 3.
o        Contiguous damages over 25 m 2 or over 2% of the total area of the tank, Sa 2½ should be applied.

This guidance notes is drawn in order to satisfy with the demands of modern shipbuilding and standard of IMO due to there is no assessment and calculation method of coating damaged areas for ballast tanks of ships all over the world.
MSC.215(82)船舶压载舱涂覆涂料前材表面定:
²       分段涂装采用丸(砂)理达到Sa2½
²       后表面理允拢对采用工具打磨,
²       小范积总和不超2St3
²       紧邻破损区域的总面积超过25 m22Sa2½
由于均没有压载舱估与算方法准,为满代造船的需求,适IMO定,特制定本指性文件。


Scope

This guidance notes prescribe the sorts, definitions of coating damages for ballast tanks of ships and the assessment and calculation method of defective areas of coating for ballast tanks of ships, etc.
This guidance notes are prepared to apply the dedicated seawater ballast tanks of new ships and double-side skin spaces of bulk carriers. Also uses for reference to other tanks.
本指性文件定了船舶压载舱的分、定及相区域面估与算方法等。
本指性文件适用于新建船舶的用海水压载舱和散船的双舷侧处所。也可供其它室参考。
