Offshore backfilling ploughs are used to backfill when laying pipelines in seabed trenches, and fenders primarily consist of an offshore backfilling plough. Research on the flow curve of the fenders is essential to decrease the working resistance of the plough during backfilling. In this work, uniflow fluid–structure interaction is developed to investigate the joint forces of the fenders under different flow curves with different working condition. An onshore field study was carried out to validate the reliability of the curve. In terms of the force of the fender, the simulation results for the fender agree with the onshore field results within a certain range of trend. To analysis of the resulting data, a better flow curve for offshore backfilling plough fenders was found.
