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.

LP-DSG: A LiDAR Point-Based Docking Spot Generation System for Unmanned Surface Vehicles in Berthing Environments

Applied Sciences
We propose a LiDAR point-based docking spot generation system for autonomous docking using point clouds from a low-density LiDAR sensor in berthing environments. The system consists of four key stages: scan matching, 3D object detection, long-term object

Analysis of key parameters and study of protective measures for wharf collision accidents

Shuili Shuiyun Gongcheng Xuebao
Ship impact has become one of the main causes of wharf damage and failure, and the damage reduces the bearing capacity and durability of the wharf structure. In order to clarify the characteristics of wharf collision accidents in China, 54 ship collision
