DNV DNV-RU-SHIPS/HSLC PART 2 CHAPTER 2 PDF

This sub-section specifies the general requirements for hot rolled steel plates, strips, sections and bars to be used in the construction of hulls and other marine structures. These requirements are also applicable to seamless steel pipes intended for structural application.

The requirements apply to plates and wide flats not exceeding 150 mm in thickness and sections and bars not exceeding 50 mm in thickness. For greater thicknesses, variations in the requirements may be permitted for particular applications.

Where required by the relevant design and construction parts of the rules, steel shall comply with the requirements of Ch.1, the general requirements of A and the appropriate specific requirements of B to E. If the specific requirements differ from these general requirements, the specific requirements shall prevail.

As an alternative to 103, materials which comply with other standards or proprietary specifications may be accepted provided such specifications give reasonable equivalence to the requirements of this section or are approved for a specific application (e.g. seamless and welded steel pipes and hollow sections for structural application). Generally, such materials shall comply with the appropriate requirements of Ch.1.
