On 14 May 2024, the GSAB2 (Grimaldi Satellite Berthing 2) project started. This is the evolution of the previous GSAB project, which had been assigned to the Grimaldi Group by the European Space Agency (ESA).
This is within its Navigation Innovation and Support Program (NAVISP) in 2022, and whose aim was to develop and validate the first assisted guidance system with satellite technology for docking manoeuvres of large PCTC (Pure Car & Truck Carrier) vessels.
As explained, after the success of GSAB, the new project will verify the suitability of the designed system to achieve the Autonomy Level 2 as defined by Lloyd’s Register: this condition is met when all actions at ship level are taken by a human operator on board the vessel, but decision support tools can present options or otherwise influence the actions chosen. In addition, GSAB2 will study the prerequisites for reaching the Autonomy Level 3, where decisions and actions at ship level are performed autonomously with human supervision.
The project is coordinated by Grimaldi Deep Sea S.p.A., with collaboration from Kongsberg, a Norwegian technology corporation specializing in processing and signal reception technology, and RINA Services, an expert in testing, inspection, classification, and certification activities. Further collaboration comes from RINA Germany and Italy’s Radiolabs Consortium, which will contribute to the design, execution, and validation of the system under real-world operating conditions.
GSAB2 will adopt the latest innovations on satellite-based multi-sensor technologies, studied and developed as part of GSAB, and will contribute to improve the efficiency of manoeuvres in port while further increasing their safety while reducing CO2 emissions, in line with the Grimaldi Group’s strategy towards a greener and safer maritime transport. In addition, GSAB2 will also develop advanced algorithms based on Artificial Intelligence as well as an interface for the functions of the Ship Automation system.
Grimaldi Deep Sea S.p.A. intends to develop and test an advisory system for safe and efficient berthing operations of large vessels. Key features include vessel positioning, navigation, and timing for autonomous sailing and operation, berth planning for port maneuvers, advisory systems for optimal sailing in confined port areas, Situational Awareness Systems, and user interaction interfaces.
In addition, the GSAB2 team will study the prerequisites for reaching the Autonomy Level 3 by establishing an exhaustive set of requirements and verification criteria. This phase will involve a joint HAZID (Hazard Identification) study of an autonomous berthing operation, the development of Key Enabling Technologies, the analysis and definition of the user interaction philosophy and visualization, the identification of prerequisites for equipment and of requirements for interfaces for an autonomous control system.
