FOREWORD
DET NORSKE VERITAS (DNV) is an autonomous and independent foundation with the objectives of safeguarding life, prop-erty and the environment, at a and onshore. DNV undertakes classification, certification, and other verification and consultancy rvices relating to quality of ships, offshore units
and installations, and onshore industries worldwide, and carries out rearch in relation to the functions.
DNV Offshore Codes consist of a three level hierarchy of documents:
—Offshore Service Specifications. Provide principles and procedures of DNV classification, certification, verification and con-sultancy rvices.
—Offshore Standards. Provide technical provisions and acceptance criteria for general u by the offshore industry as well as
the technical basis for DNV offshore rvices.
—Recommended Practices. Provide proven technology and sound engineering practice as well as guidance for the higher level
Offshore Service Specifications and Offshore Standards.DNV Offshore Codes are offered within the following areas:A)Qualification, Quality and Safety Methodology B)Materials Technology C)Structures D)Systems
E)Special Facilities F)Pipelines and Rirs G)Ast Operation H)Marine Operations J)Wind Turbines
Amendments and Corrections
This document is valid until superded by a new revision. Minor amendments and corrections will be published in a parate document on the DNV web-site; normally updated twice per year (April and October). To access the web-site, lect short-cut options "Technology Services" and "Offshore Rules and Standards" at /
The electronic web-versions of the DNV Offshore Codes will be regularly updated to include the amendments and corrections.
