A Study on Ship Berthing Support System - Minimum Time Berthing Control -

Conference Proceedings IEEE International Conference on Systems, Man, and Cybernetics, 2008
In ship's berthing at a harbor, ship operator is required to derive the maximum maneuverability from the ship. The minimum time berthing method is one of the rational and effective maneuvering methods for such tedious problems. In this paper, development of automatic minimum time berthing control system is described. And, effectiveness of the system is

Precise Maneuver Planning for Berth-to-Berth Navigation of Modern Ships

at - Automatisierungstechnik, 2015
Abstract Modern steering devices for ships lead to an improved control capability and allow independent actions without tugs by mates in use with modern electronics. Within the project AdaNav developed MIMO controller enables DP equivalent functions for ships being able to traverse.

URANS prediction of berthed ship–passing ship interactions

Ships and Offshore Structures, 2017
In this paper, the unsteady Reynolds-Averaged Navier-Stokes computational method has been employed for investigating the hydrodynamic interactions between berthed and passing ships. Initially, simulations in model-scale were performed for validating the numerical modelling technique using available benchmark experimental test cases.

Analysis of moorings of a berthed ship

Marine Structures, 1995
Abstract Ships are moored to the shore structures with a system of multiple moorings. The determination of the forces in the cables is essential for the design of moorings and for berthing structures. An optimum number and length of cables can be arrived at for a given ship of known dimensions and environrnental conditions.
