Foreword
The NORSOK standards are developed by the Norwegian petroleum industry to ensure adequate safety, value adding and cost effectiveness for petroleum industry developments and operations. Furthermore, NORSOK standards are as far as possible intended to replace oil company specifications and rve as references in the authorities’ regulations.
The NORSOK standards are normally bad on recognid international standards, adding the provisions deemed necessary to fill the broad needs of the Norwegian petroleum industry. Where relevant, NORSOK standards will be ud to provide the Norwegian industry input to the international standardisation process. Subject to development and publication of international standards, the relevant NORSOK standard will be withdrawn.
The NORSOK standards are developed according to the connsus principle generally applicable standards work and according to established procedures defined in NORSOK A-001.
The NORSOK standards are prepared and published with support by The Norwegian Oil Industry Association (OLF) and Federation of Norwegian Manufacturing Industries (TBL).
NORSOK standards are administered and published by Standards Norway.
Introduction
The principle standard for offshore structures is ISO 19 900 Petroleum and natural gas industries. General requirements for offshore structures has been approved as a European standard, and has been published as EN-ISO 19 900.
Below is a list of international standards published or under preparation. It is the intention to revi the prent NORSOK N-001 as soon as the ISO standards have been published.
ISO 19901 consists of the following parts, under the general title Petroleum and natural gas industries — Specific requirements for offshore structures:
•Part 1: Metocean design and operating considerations
•Part 2: Seismic design procedures and criteria诧异的意思
•Part 4: Geotechnical and foundation design considerations
•Part 5: Weight control during engineering and construction
The following parts of ISO 19901 are under preparation:
•Part 3: Topsides structure
•Part 6: Marine operations
•Part 7: Stationkeeping systems for floating offshore structures and mobile offshore units花园宝宝英文版
ISO 19901 is one of a ries of standards for offshore structures. The full ries consists of the following International Standards:
刘翔 伦敦• ISO 19900, Petroleum and natural gas industries — General requirements for offshore structures • ISO 19902, Petroleum and natural gas industries — Fixed steel offshore structure s
• ISO 19903, Petroleum and natural gas industries — Fixed concrete offshore structures
• ISO 19904, Petroleum and natural gas industries — Floating offshore structures
• ISO 19905-1, Petroleum and natural gas industries — Site-specific asssment of mobile offshore units — Part 1: Jack-ups
• ISO/TR 19905-2, Petroleum and natural gas industries — Site-specific asssment of mobile offshore units — Part 2: Jack-ups commentary

1 Scope
This NORSOK standard specifies general principles and guidelines for the structural design and the structural design verification of load bearing structures subjected to foreeable actions.
学威This NORSOK standard is applicable to all types of offshore structures ud in the petroleum activities, including bottom founded structures as well as floating structures.
This NORSOK standard is applicable to different types of materials ud including steel, concrete, aluminium, etc.
This NORSOK standard is applicable to the design of complete structures including substructures, topside structures, vesl hulls, foundations, mooring systems and suba installations.
This NORSOK standard specifies design principles that are also applicable to the successive stages in construction (namely fabrication, transportation and installation), to the u of the structure during its intended life, and to its abandonment. This NORSOK standard also specifies principles applicable to the re-asssment or modification of existing structures. Aspects related to verification and quality control are also addresd.
