ClassNK Approves New Corrosion Resistant Steel
ClassNK has issued approval for Nippon Steel & Sumitomo Metal Corporation’s newly developed corrosion resistant steel (NSGP-2) for use on the upper deck and/or inner bottom of crude oil tanker cargo oil tanks (COT). Following earlier approvals of steels for the inner bottom plating of COTs, this marks the first time that approval has been granted for corrosion resistant steels for both the top and bottom parts of the COT, providing owners and shipyards with a practical alternative to coating systems. In order to reduce COT corrosion and improve crude oil tanker safety, new amendments to the SOLAS Convention were issued in May 2010 requiring oil tankers over 5…
ClassNK Type Approval for World First
ClassNK issued the world’s first class approval for an immersion testing system for coatings of the inner bottom of cargo oil tanks in line with the IMO’s Performance Standard for Protective Coatings (PSPC) for cargo oil tanks to the Japanese Paint Inspection and Testing Association (JPIA). Adopted by the IMO’s Marine Safety Committee in May 2010, the new PSPC for cargo oil tanks lays out clear requirements for coating preparation, application, and service life, as well as for coating testing systems and testing processes. As the top and inner bottom of the cargo oil tank are subject to different corrosive forces, however, JPIA began…
