Current blockage: Reduced Morison forces on space frame structures with high hydrodynamic area, and in regular waves and current

Abstract:: This paper revisits the phenomenon of current blockage in offshore engineering. Standard current blockage theory was first developed by Taylor (1991) and is suited for grids of obstacles in steady flow when Morison drag is assumed locally. This is confirmed by analysis of the published experimental data on drag forces for several examples of multiple grids of obstacles in steady flow. A more complex analytical model is derived to account for the considerable extra blockage which occurs when a...
