Following our conversation at Asia Pacific Maritime — here is how we reduce auxiliary energy
consumption in real vessel operations
Reduce auxiliary energy consumption across your fleet
Delivered through control systems, variable speed drives and cloud-based
optimization
The challenge
On most vessels, auxiliary systems such as pumps, machinery fans, and HVAC operate at constant speed regardless of actual demand.
This leads to unnecessary generator load, excess energy consumption, and avoidable fuel costs.
At the same time, crews have limited visibility into how these systems perform in real operation — and limited ability to continuously optimize them.
How we solve it
Auxiliary systems are upgraded with control logic, variable speed drives, and cloud-based
optimization to match real operational demand.
Systems are continuously optimized based on live operating conditions — reducing
unnecessary load, lowering fuel consumption, and improving overall vessel efficiency.
