Project Summary
The aim of this project is to assess the feasibility of integrating a modular ISO container into the moonpool of the H-USV for the sustainable transportation of cargo in coastal and small island regions, and to offshore energy platforms, as an alternative to larger diesel crewed vessels or short-distance air transportation. The H-USV and Modular ISO Container configuration will give the vessel the flexible cargo capabilities that will ensure maximum vessel utilisation and deliver cost savings, safety improvements and emissions savings for ACUA’s end-customers.
Project Achievements
The project was divided into four work packages: Project Management, System Design, Digital Simulation, and Development Roadmap. Key tasks included defining the requirements for the container support system, producing the system design drawings in Onshape, and assessing vessel stability with various cargo loads. The assessment revealed the H-USV could support 7 tons of cargo, surpassing the initial 4- ton estimate. ACUA’s naval architecture team then optimised the system design and created a roadmap for future integration. A regulatory assessment and business model canvas were also developed, indicating that the cargo support system is technically viable with promising commercial potential.
Conclusions
The project successfully met its objectives, including designing the modular ISO cargo system, conducting the stability assessment, developing the integration roadmap, and producing a business plan for short-sea shipping. A key achievement was increasing cargo capacity from 4 tons to 7 tons, enhancing the H-USV’s, representing enhanced operational capabilities for use in the short-sea shipping and offshore support sectors. Further insights into ballasting requirements were also gained. Lastly, the project offers wider economic, social, and environmental benefits, such as supporting green logistics and creating skilled jobs. Next steps include integrating the system into the H-USV and conducting paid demonstrations for potential customers.
Next Steps
The next steps for the project involve integrating the ISO cargo support system into the moonpool of the H-USV, alongside the vessel’s final build, as part of ACUA’s broader flexible payload strategy. This strategy includes modular cargo systems as well as robotic payloads, such as ROVs and UAVs, which can be launched and recovered from ISO containers. Implementation depends on completing the H-USV build and the integration roadmap. ACUA plans to seek paid demonstration opportunities starting in Q3 2025, following vessel tests and trials in the first half of the year, aiming to reach Technology Readiness Level 8 by the end of 2025. Preliminary discussions with potential customers, including DHL, DPD, Streamline Shipping Group for short-sea shipping, and Oceaneering, ROVCO, and UTEC in the offshore renewable energy sector, have been positive, with letters of intent and support signed for future demonstrations. These partners see the H-USV’s potential for logistics, offshore support, and infrastructure maintenance.
