MARIN (Maritime Research Institute Netherlands) is involved in several projects examining the effects of passing ships. Here we present the many ways MARIN helps to shed light on this phenomenon. MARIN’s Shallow Water Basin facilitates a wide range of model testing. A recent ship passing study again showed this versatility when two complete harbours were modelled, including more than 4,000 m of their surrounding shoreline. This ship passing study aimed to investigate the feasibility of two possible new barge dock locations at an existing terminal in Beaumont.
