Review of floating object manipulation by autonomous multi-vessel systems

The regulatory endorsement of the International Maritime Organization (IMO) and the support of pivotal shipping market players in recent years motivate the investigation of the potential role that autonomous vessels play in the shipping industry. As the complexity and scale of the envisioned applications increase, research works gradually...

Cooperative Control of Autonomous Multi-Vessel Systems for Floating Object Manipulation

This thesis provides a set of cooperative control schemes for autonomous multi-vessel systems to manipulate a floating object through physical interconnections in onshore (inland waterways and ports) and offshore areas. Thanks to the maturity and popularity of the advancing technologies in information, communication, sensors, automatic control,...

Multi-vessel cooperative speed regulation for ship manipulation in towing scenarios

This paper proposes a multi-agent control scheme for multiple physically interconnected tugboats performing a ship towing process. These tugs are coordinated by two control layers. In the higher layer, the supervisory controller outputs the desired towing forces and reference trajectories for the tugs. This information is used by a tug's...
