What happens after oil and gas decommissioning? A global systematic review of marine environmental effects. [PDF]
Ecol ApplAbstract The thousands of oil and gas (OG) platforms placed at sea for fossil fuel extraction have introduced new hard substrate to the marine environment. Over time, these structures can become colonized by a diversity of marine life, fostering novel ecosystems.

Centrifuge modelling of offshore monopile foundation [PDF]
, 2010 Today one of the most used concepts for wind turbine foundation is the monopile. The foundation concepts for these monopiles on deeper water is uncertain and consequently the design needs to be conservative leading to uneconomic designs. This paper describes a total number of 6 static and 5 cyclic centrifuge tests on a laterally loaded monopile in dry ...
