Open sea berths for liquid bulk carriers

Abstract The transfer of liquid bulk through flexible transfer lines can be accomplished despite relatively large ship motions. For this reason, open sea berth terminals have replaced conventional harbors in many places. The thorough understanding of moored ships dynamics when subjected to waves, wind and currents, combined with the use of flexible dolphins, flexible fenders, asymmetric constant-tension winches and nylon tails permit us to design open sea berth terminals for relatively exposed areas. The design of an integrated system of marine sensors to continuously monitor all the critical elements-ship motion and mooring and fender forces-will enhance the operational procedure whilst insuring safe operations. A berth code can then be established for insuring the maximum efficiency of the terminal on the basis of the measurement of these critical elements.
