WIND CONDITIONS FOR LNG VESSELS IN SEA CANAL FERROL, GALICIA, SPAIN

[back to main page]

 

 

Wind forces are an important factor for ship manoeuvrability in narrow sea canals. The aim of this project is assessing the possibility of CFD to provide predictions of the wind environmental conditions in narrow sea canals surrounded by complex topography. As a case study, Ria de Ferrol, a narrow sea canal in Galicia, Spain, is considered. Large LNG vessels such as the Nakilat Q-Flex LNG Vessel need to pass through this canal, and therefore knowledge of the wind conditions is important.

The CFD results are compared with full-scale measurements. A few results from the aerodynamic analysis are shown below. More results, including the validation of the CFD simulation with on-site wind speed measurements will be added later.
