Scour and scour protection
Description
Lecture evening on "Scour and scour protection around offshore structures - new concepts and installation practice".
Scour (local erosion around a foundation) is an important issue for the oil&gas industry, but increasingly also for the renewable energy market. This puts a demand for reliable scour predictions and/or effective countermeasures, such as scour protections.
Recently, Deltares developed state-of-the-art laboratory techniques and invested in new laboratory facilities, such as the Atlantic Basin (both current and waves). Findings from model tests are translated into formulae and implemented in dedicated engineering software. In this presentation, interesting new concepts for scour protection will be introduced. Besides research in the lab, Deltares investigates the performance of scour protections in the field to validate the developed design methods.
Van Oord has a long track record in placing crushed rock in various gradations around offshore structures and pipelines as erosion protection and support, besides installation of various types of ballast material into offshore structures. Van Oord will introduce to the market during early 2011 their new, purpose built flexible fall pipe vessel "Stornes". This vessel with a loading capacity of 27,000 t and a working depth up to 1500 m is capable of placing rock on the seabed with high accuracy and in large volumes.
An introduction into the state-of-the art fallpipe technology and corresponding working methods will be given by showing a short video on subsea rock installation
Speaker(s)
Tim Raaijmakers, Advisor & Researcher Offshore Engineering at Deltares, and Maurice de Kok, Manager Subsea Rock Installation and Teus Gijzel, Project Manager Offshore Structures at Van Oord.
SPECIAL NOTES
* There will be an opportunity to join the sponsored bread meal at 18:00.
* The bread meal beforehand and the drinks afterwards will be offered by Deltares and Van Oord.
