Local buckling collapse of marine pipelines

To keep up with the growing demand for oil and gas, the oil and gas industry ventures into deeper waters. For a deep water pipeline project, South Stream, a pipeline test program is developed. Part of this program is the investigation of the resistance of an externally pressurised pipeline against local buckling collapse. This is a decisive...

Update Offshore Wind Atlas: Implementing a variable sea surface roughness

In 2005 the Energy research Centre of the Netherlands (ECN) published its first version of the Offshore Wind Atlas of the Dutch part of the North Sea [3]. This version has been updated and improved using longer time series and another approach for the calculation of the roughness of the sea surface. In contradiction to other Wind Atlases which...
