METOCEAN CRITERIA/LOADS FOR USE IN ASSESSMENT OF EXISTING OFFSHORE PLATFORMS

This paper discusses the basis for the metocean criteria and wave/current deck force calculation procedures that are included in the American Petroleum Institute (API) draft document RP2A-WSD, Section 17, "Assessment of Existing Platforms". The metocean criteria were developed in 1993 by Work Group 3 on environmental loads (WG3) of API Task Group 92-5 "Assessment of Existing Platforms to Demonstrate Fitness for Purpose". The deck force calculation procedures were developed by a sub-group of WG3. Procedures used by WG3 to obtain Gulf of Mexico and West Coast metocean criteria for various exposure categories are described in detail. The recommended procedure for calculating wave/current deck forces is shown to be validated by model-scale wave tank test data.
