They offer the flexibility to run diesel electric on high loads and use battery power at low loads. Most of the time hybrid tugs run on low load using batteries, with access to power available instantaneously as needed.
The main engine of tugboats is designed for high-power propulsion given the relatively small size of a tugboat’s hull, but most of their operation time is spent with low loads. In order to improve the performance of such ships, we came to the conclusion that a composite system was needed and developed a hybrid propulsion system.
Depending on battery size and the vessel operational profile, hybrid-powered tugs can typically reduce fuel consumption and emissions by 30-60% compared to traditional, diesel-powered tugboats. Other benefits of hybrid propulsion Hybrid-powered operations improve energy efficiency.
