Ship ModelsMarineSafety’s learning center in Newport, RI maintains a “fleet” of visual and hydrodynamic ship models. The MarineSafety commercial fleet contains almost every type and size of commercial vessel from yachts to Very Large Crude Carriers to tugs (conventional and Z drive) and barges, both ocean going and inland. The MarineSafety military fleet has a full complement of commissioned US Navy warships and two US Coast Guard cutters. MarineSafety can prepare a model for any ship, whether the ship already exists, is being built, or is merely a future concept. Our staff hydrodynamicist and center level ship modelers make maximum use of all available hydrodynamic data and, in most cases, actual ship prints to achieve the most realistic behavior possible for each ship model. Each hydrodynamic model is developed with six-degrees-of-freedom in a nonlinear mathematical simulation using 46 separate hydrodynamic terms. These coefficients are then adjusted to match sea trial and tank test data for the particular ship. Working with masters and pilots familiar with the individual ship type, the MarineSafety team validates the ship model under various load and sea conditions before it is used for training or operational research. Although MarineSafety can build any ship, many times we already have a model of the ship a client desires to use for training or research. In that case, the time and cost of preparation and testing can be saved. Specific ship specifications can be obtained from any MarineSafety learning center. We have validated ship response models for the following types:
