SEAKEEPING QUALITIES OF SHIPS PART 2: THE MIT SEAKEEPING TESTING FACILITY

A facility was specifically designed and constructed for seakeeping studies of ships. This facility has the capability (limited to head and stern seas) of recreating typical ocean wave systems as well as regular seas. Model instrumentation has been developed allowing any significant measurements to be automatically recorded during an experiment. A facility has also been developed which will automatically analyze and process both this model data and suitably recorded full-scale ship data. In addition, facilities are available which will convert the data to a form compatible with a digital computer, such that the analysis can be carried out digitally. The computer programs necessary for carrying out the analysis have been written and tested. A study was initiated for the purpose of determining what is required to recreate the sea with sufficient accuracy for seakeeping tests. Preliminary work indicates that it is necessary to specify the statistical distribution of water surface elevation or wave height in addition to the energy density spectrum.(Author)
