J. PETE 491 Project No. 5 Performed: 10/5/05 Submitted: 10/12/05 Graphical Representation of Wind Loading of Vertical Structures The awareness of wind loading and oilfield drilling equipment is necessary for protecting property and personnel. If a hurricane hit a rig with it’s pipe racked back in the derrick where side dimensions were 90 ft by 6 ft, then the area would be 540 ft 2 . This area multiplied by a perpendicular wind at 150 mph would have a horizontal load of
