Utilization of an Active Heave Compensation unit (AHC) induces an increase in a rope’s internal and surface temperatures. The primary purpose of this experimental research was to analyze the consequences of applying thermal fields on wires. Secondly, to measure the temperature generated, due to the rope’s back-and-forth movement over a sheave, while having certain inputs for the D/d ratio, the operation’s speed and the applied forces. A predictive tool to determine the wire rope’s temperature variances due to external conditions has been developed by merging the tests’ results and the analytical data.
