Investigation of Hydrodynamic Loading on Faired Towline,

Abstract

The results of an investigation of the steady-state hydrodynamic loads on faired towlines are reported. The lack of a firm basis for the engineering design of towlines is recognized as a critical deficiency in the existing technology and experimental procedures for attainment of data are presented. A test program and the experimental techniques and equipment utilized for an exploratory test are described. Test results obtained with a continuous, fully enclosed faired towline are presented. It is concluded that strong three-dimensional effects are present. Values of the resistance of the towline were observed to be approximately 2 to 2.5 times reported two-dimensional values. The possible influence of the aeration cavity on the observed results is recognized. It is recommended that additional fairing-types and at least one bare cable be tested. (Author)
