Introduction

Analysis of the core content of the standard

Technical elements	Requirements for onshore equipment	Requirements for offshore equipment
Minimum design wind speed	12.7-38.6m/s	21.6-47.8m/s
Structural safety factor	α=0.93-1.07	α=0.91-1.09
Material impact test	Optional	Mandatory for low temperature environment

Key Technology Innovations

This standard introduces the special design load table for the workover rig derrick for the first time, adds a new chapter on ice load calculation, and uses a three-dimensional wind load piece-by-piece analysis method to replace the traditional overall coefficient method, with an accuracy improvement of 40%. Typical application case: Under unexpected storm conditions, a platform derrick in Bohai successfully withstood 70kn gusts through a dual load path connection design.

Implementation points

PSL2 grade materials need to trace the heat treatment batch number throughout the process
Key welds must be 100% visually inspected + 20% surface flaw detection
Wind speed relationship curve requires linear transition stress coefficient
Offshore structure overturning safety factor shall not be less than 1.5

Standard evolution comparison

Main changes compared with the 2010 version: 4 terms such as guide rails are deleted, nameplate requirements for workover rigs are added, shielding correction factor Ks_h is introduced into wind load calculation, and Appendix C procurement guidelines are added. Major adjustments: The concept of standard ratings is cancelled and the dynamic classification of structural safety level (SSL) is used instead.
