Design Criteria1. Design Code & Standards
API-RP-2A, Recommended Practice for Planning, Developing and Construction Fixed Offshore Installations, American Petroleum Institute (API)
Allowable Stress Design (ASD), American Institute of Steel Construction (AISC)
2. Materials Properties
ASTM-A36
Fy 36 Ksi
3. Loading Super Dead Load
Walkway 67 lb/ft2
Handrail 34 lb/ft
Live Load
Oil Pipe 60 lb/ft
Water Pipe 48 lb/ft
Pedestrian 75 lb/ft2
Wind Load (Base elevation is 75 feet above MSL)
Operating wind speed 25 mph
V (75) = 25(7510
