Energy–Time Co-Optimization for Autonomous Ship Berthing in Complex Ocean Currents Using an Improved hp-Pseudospectral Optimal Method

Journal of Marine Science and Engineering
Berthing path planning for ships in the presence of ocean currents is a challenging task. Several relevant methods have been proposed, but they all assume a constant surge velocity for the whole path.
