The Dynamic Behavior Of Mooring Lines

Abstract

In this paper th~oresults are presented of _a model study into the behaviour of anchor lines as used in the offshore mooring of a wide variety of floating structures. For this study model tests have been carried Qut with a buoy moored to four chains. The effect of model scale, pre~tension in the lines, wave height and wave period on the line tensions is discussed. Special attention is given to the dynamic behaviour of the mooring system, resulting into higher tensions than would follow from-calculations based upon the static catenary theory. The existence and significance of dynamic effects is confirmed by the results of forced oscillation tests with model anchor-chains in calm water.

A novel underwater measurement method for mooring system using self-contained technique

“…Numerical analysis methods and conducting model tests are conventionally employed in the study of mooring lines. [3][4][5][6][7][8] However, simplifying the model introduces uncertainties that are difficult to quantify in the calculation. Moreover, model tests have been challenged with the increase in the water depth of marine resources.…”
