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 serve as

references in the authorities’ regulations.

The NORSOK standards are normally based on recognised international standards, adding the provisions

deemed necessary to fill the broad needs of the Norwegian petroleum industry. Where relevant, NORSOK

standards will be used 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withdrawn.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 consensus principle generally applicable for most

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), The Federation of Norwegian Industry, Norwegian Shipowners’ Association and The Petroleum Safety

Authority Norway.

NORSOK standards are administered and published by Standards Norway.

Introduction

This NORSOK standard is the principal standard for offshore structures. The standard especially refers to

ISO 19900, Petroleum and natural gas industries - General requirements for offshore structures.

It is the intention to revise this NORSOK standard as soon as the International Standards adequately

covering the scope of this NORSOK standard have been published.

Changes since last edition are as follows:

 the reference list is updated;

 4.2 is changed;

 new 4.8 related to interface assessment;

 7.10 is changed, with new list items b) and i);

 new 7.13 Design of weak links;

 some minor editorial updates.
