Azipods are increasingly being used particularly to large cruise vessels yet there is presently no established design method for scour protection subject to their action. These vessels can create high flow velocity to berths which makes rock protection impractical. Following scale model testing, design methods for scour protection will be presented for single and multiple azipods.<br \/>\nA \u2018falling hinged\u2019 edge detail has been developed for high velocity flows and as an alternative to rock falling edge aprons. The detail is used with insitu concrete mattress protection and comprises heavy in-situ concrete blocks which are linked to fall with edge scour. The relative merits of hinged edges and rock edges will be reviewed. A basis for the design and use of falling hinged edges is presented.<br \/>\nMaintenance dredging to berths with scour protection is an increasing issue with developing vessel size and often lower hull clearances, yet little up to date guidance is available. Views for the selection of resilient scour protection are given for common maintenance dredging actions with reference to PIANC WG22 (1997).<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The paper seeks to advance knowledge to three important aspects of berth scour protection.
