Innovations in Dredging set for February 26

WEDA’s next webinar – Innovations in Dredging – will take place on Friday, February 26, 2021, from 11 AM to noon EST. 

The Innovations in Dredging Webinar will feature two presentations by Aiden Horan, the Vice President Of Engineering & Innovation, J. Cashman, Inc., and Xiuhan Chen, the Vice President, ANAMAR Environmental Consulting, Inc.

A 3D Analytical Model for Linear Rock Cutting Process

This research explains the analytical derivation for upgrading the current rock cutting models from 2D to 3D, from cutting with sharp tools to cutting with wear flat.

The analytical derivation is supported by experimental research.

Innovative Scow Boarding System

A typical split hull dump scow has an air draft ranging from around 20ft (to the scow walkway surface) when empty to roughly 4ft when loaded.

This large range of vertical movement has made safe man access to the scow troublesome at times.

The traditional solution for access to the scows is either using a hinged ladder attached to the deck of a dredge which is swung into position when needed and placed in a storage position away from the scow when not in use or via the pigeon holes on the side of the scow.

This hinged ladder system is adequate for a lite scow when the ladder is used within normal ladder parameters, but the more a scow is loaded the shallower the angle becomes for the hinged ladder until it can no longer safely perform the function for which it is intended.

The use of the hinged ladder is sometimes not safe depending on the weather conditions or sea state.
