The Large Towing Tank is mainly used for propulsion performance tests and seakeeping tests for ships and offshore structures.
Large Towing Tank
PCs set on the towing carriage automatically operate and control standard tests in still water such as resistance tests, self-propulsion tests, wake measurement tests, propeller open water tests, and data processing to improve the accuracy and efficiency of those tests.
Standard examinations in still water such as resistance tests, self-propulsion tests, wake measurement tests, and propeller open tests, are efficiently and accurately measured by unmanned operation of the towing carriage and automatic data collection system.
