... ABSTRACT The subsea structure layed on the seabed has effect on the current flow in the ocean engineering. The complex current flow disturbs sediment around the subsea structure and scour the structure foundation. If the depth of scour hole is too deep and makes the foundation have uneven...

Model tests are often necessary to study and document such transient and complex flow phenomena. coanda effect thruster-hull interaction model test interaction thrust loss current flow...

... of a moored.float, whose prototype corresponding to a large-scale floating structure like a tension-leg-platform, under the actions of current flow has been conducted. The response characteristics due to fluid drag and lift forces are investigated. The models were placed in a circulating water channel under...

... of current flow. The traces of response vibrations were recorded and analyzed. The results indicate that the horizontal components of responses increase with flow velocity due to higher fluid drag forces. The variation in the vertical components is much more complex and is influenced by the eddies and other...

The inertia coefficient was found to be strongly affected by the variation of the cylinders" aspect ratio. In combined waves and current flow...
