![]() ![]() ![]() The results show that under the same environmental conditions with the same tanker tonnage, the SALM terminal mooring system shows a greater fatigue life. For simulation, the hydrodynamic response characteristics of terminals and tankers are first calculated using ANSYS AQWA software, and then the outputs are imported into ORCAFLEX software for fatigue analysis. A comparison is made between CALM and SALM mooring fatigue designs based on the conditions of the Persian Gulf region. Stress amplitudes are calculated based on the tension amplitudes of the mooring lines under the combined loading process due to wave frequency (WF) and low frequency (LF) motion. T-N curves-based mooring system fatigue analyses for a CALM and SALM oil terminal are presented. ![]() Most of these failures have been caused by fatigue load. However, over the past few decades, mooring accidents of permanent floating structures have occurred quite frequently in the last few decades. Safety is crucially important for offshore terminals. There are several types of offshore terminals, including Catenary Anchor Leg Mooring (CALM) and Single Anchor Leg Mooring (SALM). Offshore oil terminals are a cheaper and safer solution than conventional shore terminals for unloading and loading tankers. ![]()
