Ice Tank
An ice tank is a ship model basin whose purpose is to provide a physical modeling environment for the interaction of ship, structures, or sea floor with both ice and water. Ice tanks may take the form of either a towing tank or maneuvering basin. Many un-refrigerated ship model basins use ice simulants such as paraffin wax, plaster, and mixtures of foam or plastic beads. The cleanup and handling of such simulants often proves cumbersome. What differentiates an ice tank from other ship model basins is that an ice tank has purpose built provisions into its structure for handling such material conveniently. Use of a refrigerated basin containing mostly water allows freezing and melting to be a convenient method of model ice preparation and cleanup. Ice scaling Ship model basins often simulate full-scale processes in miniature. Ships and structures are reduced linearly in size, and cubic in mass, displacement, and volume. The challenge in ice modeling is correctly reducing the ice ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ship Model Basin
A ship model basin is a basin or tank used to carry out hydrodynamic tests with ship models, for the purpose of designing a new (full sized) ship, or refining the design of a ship to improve the ship's performance at sea. It can also refer to the organization (often a company) that owns and operates such a facility. A ship model basin company is an engineering firm that acts as a contractor to the relevant shipyards, and provides hydrodynamic model tests and numerical calculations to support the design and development of ships and offshore structures. History The eminent English engineer, William Froude published a series of influential papers on ship designs for maximising stability in the 1860s. The Institution of Naval Architects eventually commissioned him to identify the most efficient hull shape. He validated his theoretical models with extensive empirical testing, using scale models for the different hull dimensions. He established a formula (now known as the Froude nu ...

Krylov State Research Centre
The Krylov State Research Center (russian: Крыловский государственный научный центр) is a Russian shipbuilding research and development institute, which operates as a federal state-owned unitary enterprise.

CRREL
The Cold Regions Research and Engineering Laboratory (CRREL) is a United States Army Corps of Engineers, Engineer Research and Development Center research facility headquartered in Hanover, New Hampshire, that provides scientific and engineering support to the U.S. government and its military with a core emphasis on cold environments. CRREL also provides technical support to non-government customers. CRREL arose from a consolidation of three antecedent organizations whose purpose was to understand frozen ground, permafrost, snow and ice as factors which were important in strategic northern areas during the Cold War. In its first 25 years CRREL researchers contributed to the understanding of polar ice caps, permafrost, and the engineering technology for developing natural resources in cold climates, such as Alaska. More recently, CRREL researchers have made contributions to science in climate change, the understanding of wave propagation for sensor systems, the control of snow on ...
