Investigation on a Novel Support System for Automatic Ship Berthing in Marine Practice
For safe ship berthing, all steps involved, from bringing the ship to the fairway area to directing it to the final wharf position at a desirable speed, need to be performed properly. In this article, a support system is proposed to automatically bring the ship into the berth after completing the ma...
