Abstract:The size of the ships which navigate in seas and inland waterways is increasing, mainly for economic reasons. A bigger ship needs a bigger thrust force to push it forward. Large vessels with the powerfulpropellants usually equip a bow thruster for effective ship operation. Subsequently a higher velocitypropeller wash is induced. However these thrusters generate the strong current which may cause a local scour in front of a quay wall and affect its stability. The loads on bottom protection differ,because of diversity in shipping and tidal motion. This paper reports the development of a newremotely operated vehicle (ROV) based test facility and purpose-built by the authors to investigate unsteady dynamics of large marine thrusters on the profile of sedimentations near a quay wall ofShahid Rajaee harbor. Laboratory experiment has been conducted to measure the local scour due tojet-like strong current which simulates, the strong current due to main and bow thrusters. The demands of stability required to guarantee a stable and safe bottom protection, this bottom protection is studied with soundings.
