Acceleration Measurements on Board of the Dock Express 11, 12 and 20 Heavy Lift Ships

摘要

In 1983 a project was initiated to measure accelerations on board of three practically identical ships in order to provide information on the long-term statistical behavior of 'accelerations on cargo.' In the report the measured acceleration levels will be compared with the 'characteristic accelerations' according to the DNV rules for these ships on the same route. Also comparisons will be made with the design values proposed by Dock Express and with the results of a long-term prediction method available at the Maritime Research Institute, Netherlands (MARIN). The measurements on board of the Dock Express 11, 12, and 20 commenced after installation of the equipment by MARIN technicians. The equipment was duly tested prior to installation. The measurement results were stored on diskettes which were converted to magnetic tape files by Troost Systems B.V. The magnetic tape files were stored at MARIN and used for analysis and investigation.
