Abstract
The increasing number of research regarding mooring systems promoted changes in the offshore industry, such as the replacement of steel cables by synthetic ropes, and the development of new types of anchors. In 2004 Petrobras designed the torpedo pile. The procedure of inserting the anchor to the seabed is a consequence of a free fall mechanism, however, during the installation of the torpedo anchor, an unexpected stop of the launching system might happen, causing an impact load to the synthetic anchoring cables. The synthetic cables are also used for others activities like towages of ships and climbing sports, and might eventually be submitted to abrupt axial loads. Mainly for climbing sports, the polymeric ropes are an important equipment to protect the climber in a fall situation. Addressing these issues, this work aims to assess mechanical behavior of polyester (PET) ropes, produced by manufacturers A, B and C, when submitted to impact tensile stress, analyzing their fatigue life after the occurrence of an impact load.
