With tightening environmental regulations like EEXI, CII, and the IMO 2050 decarbonization targets, and rising fuel costs, shipowners and operators face growing pressure to optimize vessel efficiency. Hoyer ESS meets this challenge by combining Variable Speed Drives (VSDs), intelligent sensors, and automation to dynamically control engine room fans, seawater cooling pumps, freshwater cooling pumps and other marine applications. Not only does this mean energy and fuel savings, it also reduces CO₂, SOx, and NOx emissions, and extends the life of critical ship equipment.
"Hoyer ESS is not just another control system - it is a unique and scalable retrofit solution that delivers real, measurable results," says Palle Grankvist, Global Business Development Manager, Automation Solutions at Hoyer. "Shipowners today need solutions that are easy to implement, provide a fast return on investment, and deliver immediate operational and environmental benefits. With Hoyer ESS, we’re offering exactly that."
A recent installation with a European shipowner saw annual energy savings of over 1.4 million kWh, fuel savings of 290 tons, and CO₂ reductions of 628 tons, with a payback time of under two years. Designed for easy integration, Hoyer ESS installations are completed while vessels are in operation, ensuring no service interruptions.
The launch builds on Hoyer's focus to develop advanced automated solutions for motor applications for the marine, industrial, HVAC, and energy sectors. Earlier this year, Hoyer acquired software automation developer NowiTek, whose technology and industry knowledge lie at the core of Hoyer ESS.
