IADC Release Paper on Dredging Sound Levels

In their latest issue of Terra et Aqua, the International Association of Dredging Companies (IADC) has released a new article named ‘Dredging sound levels, numerical modelling and EIA’.

This paper was initially presented at the CEDA Dredging Days in November 2015 and was included in the conference proceedings.

Underwater sound from anthropogenic sources and its potential adverse effects on the marine environment is a topic of much global interest.

In recent years, there is recognition that sound from some shipping and dredging activities could have impact on the marine environment, particularly in deep sea areas where low frequency sound can travel long distances.

Dredging activities emit underwater sound in the marine environment.

Monitoring of sound from dredging equipment is occasionally carried out for an individual project and usually only to support research.

Because of the way in which sound interacts with the marine environment, the propagation of sound from individual dredging vessels will vary depending on the activity and location of the dredging.

The level of sound at the dredger, termed the source level, will also vary between dredgers due to a range of different environmental and mechanical factors.

3rd International Congress Hydraulic Engineering Structures and Dredging

Russia’s leading maritime industry Media Group PortNews (www.portnews.ru) holds a traditional annual Congress “Hydraulic Engineering Structures and Dredging” in Moscow. 

The two-day Congress includes the 7th International Forum of Dredging Companies and the 3rd Technical Conference “Modern Solutions for Hydraulic Engineering”.

Infrastructure development is among the real sources of Russia’s economy growth. Construction of port facilities and new hydraulic engineering structures on the country’s inland waterways constitute an essential part of all infrastructure projects. It is important to take into account the best international practices to implement these projects effectively.

The program of the Congress will be devoted to the latest technologies for dredging and hydraulic engineering works. Speakers and delegates will refer to real projects to discuss specifics features of dredging works, as well as dedicated fleet and equipment involved.
