Lake Macquarie, renowned for its picturesque waters, and over time the region has seen innovations in technology across many sectors. Aquatic activities are synonymous with this region, now Ampcontrol has provided another evolution in innovation. They have designed a hybrid propulsion system aimed at revolutionising maritime operations. Reducing noise, emissions, and eliminating operational range anxiety, they have collaborated with Steber International and the University of Newcastle, Ampcontrol have taken a pivotal step by developing a 43ft hybrid vessel showcasing the substantial performance and economic advantages of hybrid power systems. With potential applications ranging from law enforcement patrols to search and rescue missions.
The Steber 43ft Hybrid vessel stands as a testament to cutting-edge engineering, employing a series hybrid topology that optimally harnesses electric propulsion capabilities. The system integrates an on-board battery system with a marine-grade diesel engine, reconfigured to drive a high-power electric generator efficiently. Key components include two permanent magnet synchronous electric motors, each rated at 300kW continuous power, directly linked to the propellers. This setup not only embraces fly-by-wire technology but also delivers precise propeller torque and speed control.
One notable feature is the vessel’s docking mode, engineered to lower propeller speed while maintaining full control of operational range, easing navigation in confined waters and during docking manoeuvres. The 150kWh marine-grade battery system empowers the vessel to seamlessly transition to electric-only propulsion, exhibiting impressive range capabilities across varying speeds, from 4 to 20 knots.
The incorporation of closed-loop isolated glycol liquid cooling circuits for major electrical components ensures efficient heat dissipation, component redundancy, and pump size reduction. Rigorous testing has validated the system’s performance under challenging conditions, simulating operations in warm water environments exceeding 33°C, akin to regions like Cairns, Darwin, and Broome.
Furthermore, the Steber 43ft vessel integrates Aware Marine remote monitoring software, enabling real-time position tracking and system status monitoring. This enhances operational visibility and enables proactive maintenance strategies, ensuring optimal performance and longevity.
The successful deployment of the 43ft hybrid vessel has garnered attention across maritime sectors. The modular and scalable nature of the hybrid electric power system opens avenues for tailored performance profiles in both new builds and retrofitted vessels, promising a sustainable and efficient future not just for Lake Macquarie, but for waterways around Australia and possibly the World.
