API Recommended Practice for Planning, Designing and Constructing Fixed Offshore Platforms – Working Stress Design
The purpose of this specification is to provide engineering design principles and good practices that have evolved during the development of offshore oil resources. In no case is any specific recommendation included which could not be accomplished by presently available techniques and equipment.
Design, Fabrication and Erection of Structural Steel for Buildings (see Section 2.5.1a). While the use of latest edition of this specification is still endorsed, the use of the new AISC Load & Resistance Factor Design (LRFD), First Edition is specifically not recommended for design of offshore platforms.
The load and resistance factors in this new code are based on calibration with building design practices and are therefore not applicable to offshore platforms. Research work is now in progress to incorporate the strength provisions of the new AISC LRFD code into offshore design practices.
