Resumo:
The purpose of this graduation project is the design and structural evaluation of an adaptable clamp for several different flexible lines diameters. This kind of equipment is already being used by the petroleum industry, however, the typical clamps available are still facing limitations, especially regarding its restriction to fit flexible lines different diameters, since they are designed for a specific size. As presented in this project development, this component preliminary dimensioning was performed by bolt preload and pad eye analytical calculations, according to Shigley (1) and Petrobras standard N-2683 ( Oceanic Structures - Eyelet Lifting - Design REV. B Dec./2010) (2), respectively. Finite element analyses assisted by ANSYS Workbench 14.5 were also performed considering the most critical load generated by the flexible line weight, in order to define this clamp maximum dynamic capacity and evaluate its structural design. The results obtained by this project certifies that the design created based on this adaptable clamp concept is in accordance with the acceptance criteria established by internationally recognized standard codes, such as Lloyds (3) and DNV (4), which implies that the component must not exceed an allowable stress when in operation.
