Austal Australia has taken possession of a de-commissioned Armidale-class Patrol Boat (ACPB), the former HMAS Maitland, from the Commonwealth of Australia, to commence planning, modification, and test and evaluation of autonomous and remotely operated systems.
The Patrol Boat Autonomy Trial (PBAT) is a collaboration between Austal, Trusted Autonomous Systems Defence Cooperative Research Centre and the Royal Australian Navy Warfare Innovation Navy (WIN) Branch.
The trial will aim to establish robotic, automated and autonomous elements on a patrol boat, providing a proof-of-concept demonstrator, for optionally crewed or autonomous operations for the RAN into the future. The trial will also explore the legal, regulatory pathways and requirements of operating an autonomous vessel at sea.
PBAT couples Austal’s experience as the designer and manufacturer of the Armidale-class Patrol Boat (ACPB), with subcontractor L3Harris’ experience in autonomous vessel technology. With co-funding from the Commonwealth of Australia, guidance and support is provided from the Trusted Autonomous Systems Defence Cooperative Research Centre.
Following the arrival of the vessel in Henderson, Western Australia, the re-named ‘Sentinel’ has entered the trial’s ‘modification phase’; which includes the fitting of a variety of monitoring and control systems and technologies that enables autonomous and remote operations. From July 2023 the vessel is expected to be registered under Australian Maritime Safety Authority (AMSA) jurisdiction as a domestic commercial vessel to enable sea trials to commence October 2023.
According to Austal Australia, the PBAT project aims to:
- Significantly progress the concept of remote operations and the autonomous certification approach;
- Increase the understanding of fuel management, communication, and navigation systems to be made autonomous;
- Investigate and understand the sustained operation of shipboard mechanical systems without crew intervention, including systems of redundancy and reliability to support operations at sea for extended periods;
- Provide input to long-term risk reduction for future naval projects, considering remote or autonomous vessels. This will be extended to other sensors and autonomous vehicles once the initial trial is complete; and
- Transfer lessons learned on the application of remote or autonomous systems to the Royal Australian Navy’s current fleet to potentially optimise crew workload. Remote and autonomous operation has the potential to reduce crew workload and increase operational safety by reducing human error.
“Austal understands the future of Australia’s maritime capability will partly depend on how quickly our naval enterprise can better understand and integrate autonomous and remotely operated vessels," Austal Limited Chief Executive Officer Paddy Greg said.
“Austal are pleased to be at the heart of Australia’s autonomous naval journey, working with our Industry partners, Navy and the Commonwealth, to complete the modification and trials, and share this data to improve the wider knowledge base.”
“Our expert staff are excited to be working to learn more about the challenges and opportunities in this autonomous and robotic space.
“Austal always strive to improve our designs and build ships that outsmart Australia’s adversaries, delivering capability into the hands of the Australian Defence Force to improve their ability to fight and win at sea,” Gregg said.
