State-of-the-Art Review and Future Perspectives on Maneuvering Modeling for Automatic Ship Berthing

open access: yesJournal of Marine Science and Engineering, 2023
Automatic berthing is at the top level of ship autonomy; it is unwise and hasty to hand over the control initiative to the controller and the algorithm without the foundation of the maneuvering model.

Optimizing ship berthing [PDF]

open access: yesNaval Research Logistics, 1994
Abstract : Ship berthing plans reserve a location for inbound U.S. Navy surface vessels prior to their port entrance, or reassign ships once in port to allow them to complete, in a timely manner, reprovisioning, repair, maintenance, training, and certification tests prior to redeploying for future operational commitments.
