Survey Sequence Important to Predicting Underwater Landslides
Submarine landslides can hamper the productivity of offshore installations, but researchers at Texas A&M may now be able to accurately predict the occurrence of marine landslides using underwater site characterization data.Although data from personnel with different expertise are needed to tell the story of the land below the sea, the order in which they perform their tasks toward site characterization is important, says Zenon Medina-Cetina, associate professor in the Department of Civil & Environmental Engineering. This sequence, if violated due to budgetary or time constraints, could lead to

Stakeholders Wary of Partial Decommissioning of Offshore Wind Farms
decommissioning can be considered in advance, rather than close to when it is due to take place. However, the researchers also acknowledge that today’s preferred decommissioning methods may become obsolete, and change depending on societal attitudes and ecological findings.In the Netherlands, two offshore wind farms are due to be decommissioned in the near future: Egmond Aan Zee (by 2027) and Prinses Amalia (by 2028). Dutch legislation requires that the wind farm owner should submit a plan for decommissioning to the Dutch government, which involves leaving the site “in an equal state&rdquo
