In order to fulfil the requirement regarding materials and material protection as mentioned in literas a, b and c, the following standards should be used in the area of health, working environment and safety:
- NORSOK M-001 for material selection,
- NORSOK M-101 for steel structures,
- ISO 13623 Chapter 8 and DNV-ST-F101 Paragraphs 6 and 7 for pipeline systems,
- DNV-ST-F201 Paragraph 7 for catenary metallic risers,
- API 17J Chapter 6 for flexible pipeline systems,
- NORSOK N-001 for concrete structures,
- NORSOK M-501 for choice of coating, pre-processing, application and inspection,
- NORSOK M-503 for cathodic protection,
- NORSOK M-601 for piping systems,
- NORSOK M-004 for insulation of equipment.
For
mobile facilities registered in a national ship register, the following standards can be used as an alternative in the area of health, working environment and safety:
DNV-OS-B101 for metallic materials,
DNV-OS-C102 Paragraph 2 Section 1 for ship-shaped facilities,
DNV-OS-C103 Paragraph 2 Section 1 for semi-submersible facilities and
DNV-OS-C104 Paragraph 2 Section 1 for jack-up facilities.
Methods for control of manufacture and assembly as mentioned in litera b, may include materials control where the sample materials represent the product with regard to manufacture processes, geometrical design and dimensions. Requirements regarding surface quality should be specified in connection with carrying out non-destructive testing of forged and cast goods.
When choosing materials as regards
fire-resistance characteristics as mentioned in litera d, non-flammable materials should be chosen. Where flammable materials are used, they should limit the spread of fire and produce little smoke, heat and toxic substances. In living quarters, electrical installations should be constructed of halon-free materials. The flame spread and smoke development qualities of the materials should be considered when textiles or surface treatment with paint or other coating is used. To determine the technical fire qualities of materials
NORSOK standard S-001 Chapters 20.4.5 and 20.4.6 should be used.
When choosing materials in light of the employees' health and working environment as mentioned in litera h, materials should be used which are not harmful to the employees alone or in combination with other materials or gases. When choosing materials and surfaces, emphasis should be placed on comprehensive solutions adapted to the intended use and cleaning and maintenance requirements.
