Auxilia for Commercial Vessels
The document describes Auxilia's hybrid drive system for commercial vessels. The system uses electric motors and diesel generators to provide propulsion and ship power. Electric motors can be directly mounted or remotely mounted to diesel engines. This allows ships to operate quietly and efficiently at low speeds using electric power alone or together with one diesel engine, reducing fuel use and emissions. Auxilia's systems provide benefits like redundancy, lower maintenance costs, and can be retrofitted to existing vessels.

For the commercial vessels, Auxilia offers an auxiliary propulsion system consisting of e- motors, drivers, PMS (Power Management Sy- stems) gensets and control levers. Furthermore Auxilia could supply all components of the pro- pulsion system in a complete package (reduc- tion gearboxes, shafts and propellers or POD systems). The electric motor, up to 200 kW, is solid mounted with the diesel engine housing (direct mounted). For the versions over 200 kW only the clutch is coupled to the diesel engine but the e-motor is connected to the main engine through a shaft and installed on rigid mountings (remote mounted). Both versions act on the same shaft and on the same propeller; the clutch between the e-motor and the diesel en- gine permit to disengage the main engine from the propulsion system when the e-motor is on. Auxilia can be used in alternative to the main diesel engine. With the clutch disengaged, the e-motor can take the ship from the harbour out into the open sea (shutdown of main engines, power from gensets or batteries) and cruising at 6-10 knots with excellent fuel economy, low emissions, faster accelerations. If the captain then decides to go at full throttle, he will deploy the full power of his diesel engi- nes. The clutch will engage and the combustion engines take over the ship’s propulsion. During this phase the e-motor can works in two pro- pulsion modes: as a generator recharging the batteries or producing electricity for the ship load or in booster mode to increase the speed/ acceleration. For long distances when cruising at moderate speed, in order to save fuel (and CO2 emissions) the captain may shut down one diesel engine and drive the second propeller using the electric motor (e-shaft mode with two shaft line).
