PSE Petroleum Engineering Software, by Safi Quality Software, Inc. software

Wind loads, based on the velocity component approach, are defined according to API 4F Specification for Drilling and Well Servicing Structures (5th edition). The API 4F specifications for wind loads based on the velocity component approach is integrated into the PSE Petroleum Structural Engineering software. Accordingly, drilling structures are classified based on their Structural Safety Level (SSL) and their offshore or onshore location. The design reference wind velocity Vref value chosen should be a 3-second gust wind measured at an elevation of 10 m (33 ft) in open terrain or water, with an associated return period of 50 or 100 years.
