CHAGOYEN-MENDEZ, César A. et al. MODELLING AND ANALYSIS OF TOWER INTERVENTION EQUIPMENT OF OIL & GAS WELLS. cen. az. [online]. 2015, vol.42, n.2, pp. 21-30. ISSN 2223-4861.

In this paper, the modeling and analysis of one tower Workover Rig belonging to a maintenance facility for oil and gas wells is presented. When performing the maintenance of this tower, it is detected that one of the elements of the structure has some deformation. It was decided not to put it into operation and submit it to research.The modeling of invariants as well as ways of modeling soil structure interaction is discussed. It was necessary to determine the material properties with the performing of test of some samples taken on two components of the tower.The structural behavior of the tower to operating loads are then studied, proving that the effect of the deformed element in the structure is not significant for the stresses to which are subject.
