Abstract

The present work presents the results of installation tests of reduced scale torpedo pile anchors assisted by fluidization process created by the application of circular vertical water jets. The influence of the imposed flow and the mass of the anchoring element were evaluated. The prototype analyzed was a 66-ton T66 torpedo pile type. The tests were carried out in an experimental field of sandy soil with models reduced in the length scale 1:12, according to the Law of Similarity by Froude Number. The flow rates applied were 10.35, 22.81, 30.71 and 41.60 L/min. The test results showed great agreement with similar research carried out in the laboratory with smaller scales than the one evaluated in this work. It was observed that the increase in flow increased the penetration depth of the models, as for a given flow, the pile with greater mass has greater penetration. The tests showed that the fluidization process contributes to increasing the depths of this type of offshore anchoring system and that the correct choice of flow rate and mass of the torpedo pile can improve the installation procedure.
