Abstract:

The report contains an engineering and economical evaluation of eight different concepts of floating fenders to be considered for Navy docks. The engineering aspects involve discussion of different design criteria, such as vessel approach velocities, acceptable lateral dock loads, hull loads and stresses in structural timber. A description of the dynamics of a berthing ship is given, including a discussion of the various energy correction coefficients to be used. The hydrodynamic mass coefficient is especially emphasized. The results obtained on this coefficient by many different investigators are summarized, showing that large unexplained discrepancies exist. The economic criteria employed are stated and summarized. A short discussion on deterioration of camel materials is also included. Due to inadequate data on maintenance costs, these calculations had to rely mostly on engineering judgement and intuition. Fairly detailed engineering descriptions and calculations as well as economic evaluation of every concept is included. Conclusion and recommendations based on the study are given as well as a preliminary final design. Author
