| Abstract: | Some critical welding process problems of low temperature service steel on type-A cargo tank and secondary barrier of 83000m3 LPG carrier that is first built in China are discussed in this paper. The research about welding process tests of low temperature service steel, arrangement and mechanical property of welding production test pieces, NDT plan for type-A cargo tank and secondary barrier have been carried out. CCS has approved relevant design drawings, proposed some guide suggestions, and formed relevant stands. CCS has provided the technical support to ensure 83000m3 LPG carrier to be well built, and delivered on schedule. |
