Abstract Floating offshore wind turbines are a nascent technology with demonstrated potential of harnessing the substantial prevailing wind energy in water depths beyond the commercial limits of fixed offshore wind farms. While the latter are competitive with conventional sources of electrical...

In this way, we define a sufficiently broad simulation space...

... by varying water depths from 100 to 1100 meters. All these constraints are included on the calculations that aim to verify the hydrate inhibitor injection rate needs in the well and define the best flowrates to swap. The results emphasize the critical role of tubing temperature in transient injection...

... criteria—equivalent strain and equivalent stress—are assessed to determine optimal design parameters. The study considers water depths up to 200 m and a 5 MW wind turbine exerting a 1,600 tf pullout load on an anchor. The results show that a minimum anchor body thickness of 28 cm is required to satisfy...
