DNVGL SHIP TECH I-1-5A
I-Rules for Classification and Construction Ship Technology Part 1-Seagoing Ships Chapter 5a-Supplementary Rules for Application of Steel with Yield Strength of 460 N/mm2 as well as Extremely Thick Steel Plates of Different Yield Strength
|Publication Date:||1 July 2014|
The application of hull structural steels with yield strength of 460 N/mm2 is limited to structural members of the upper hull of container ships. The implementation is associated with some innovations, which are addressed in these Supplementary Rules. Furthermore and particularly if no additional requirements are stated in these Supplementary Rules the application is to be in accordance with GL's Structural Rules for Container Ships (I-1-5) and the GL Rules for Metallic Materials (II-1) and Welding (II-3).
For ship types other than container ships the application of this steel has to be agreed with GL individually.
