Research Regarding Drilling Masts Reliability under the Combined Action of the Wind and the Hook Load
Journal Title: Tribology in Industry - Year 2015, Vol 37, Issue 1
Abstract
Portable masts are parts of mobile servicing rigs designed to work at drilling or extraction wells and are made of three sections: fixed section, lower section and upper section. During transportation, the mast is placed in a horizontal position on a truck chassis, with the upper section nested inside the lower section. Before putting into service the mobile servicing rig, the lower and upper sections are erected as a unit, in a slightly inclined position. In this paper, the authors present the results of a research regarding the safety in functioning for such a mast which is under the action of the wind with high velocities. The wind’s action direction with respect to the mast is analyzed in two cases: front-back and lateral, with stress and strain values that occur.
