Top trends in marine generator sets

INCREASINGLY BEING USED FOR HYBRID APPLICATIONS, MARINE GENERATORS ARE EVOLVING INTO SOPHISTICATED, MULTI-SPEED SYSTEMS THAT CAN ALSO HARNESS RENEWABLES TO SAVE FUEL

JAKE KAVANAGH AND CRAIG RITCHIE REPORT

“BOATS ARE BECOMING more like houses,” says Riccardo Snaidero, sales manager for Italian generator manufacturer Volpi Tecno Energia (VTE). His statement reflects the general opinion of the marine off-grid power sector as it evolves to meet an almost insatiable appetite for AC power afloat. “Owners want their boats to be as comfortable as possible, with equipment such as air conditioners, watermakers, and modern kitchen appliances installed on board. All of these require a high consumption of energy.”

Ultimate power efficiency – the Volvo Ocean Race

TO ILLUSTRATE JUST how efficient power generation and management has become, take a look at the most recent Volvo Ocean Race. Each identical 65ft yacht had exactly the same Mastervolt set-up, with a Volvo diesel spinning up a pair of high-efficiency alternators. With limited fuel to save weight, the charge cycles were few and far between. “The boats went through a charge cycle every 24 hours,” says Mastervolt’s Ton de Winter, EMEA business leader at Mastervolt’s Dutch headquarters. “Each 59-minute cycle supplied roughly 240-280Ah of current to the Mastervolt Lithium-ion batteries at 24V, and is also used to run the watermakers. The two Mastervolt alternators produced 300Ah at 24V, so they could get the Li-ion batteries  Manufactuers such as Mase and Fischer Panda are all striving to reduce the footprint and noise of their recharged very quickly.

Variable-speed motors and the use of permanent ran through our Mastervolt CZone Digital magnets are all helping Switching Platform. This system needs the same resilience and redundancy as the Li-ion Expo now in its fifth year.

Small generator – Featured system schematic big battery bank

WITH THE MUCH greater storage capacity available from Lithium-ion technology, there is a move towards using an ‘energy bank’ in concert with a smaller generator. The idea is that the energy bank is recharged ‘off peak’ or when there is surplus energy, and then tapped into at times of peak demand to supplement – or even replace – the generator. One such system, called New School, has been developed by Dutch-based WhisperPower, and is reported to be enjoying considerable success following trials with Dickey Boats in Auckland, New Zealand. The heart of the system is a large bank of Lithium-ion batteries, equivalent to the total peak load of the boat. A variable speed ‘Genverter’ would be able to recharge this bank in around six hours, and would run during the day when noise is less of an issue. Everything is managed via WhisperPower’s DC Powercube, including input from any renewables. When peak power is required, the boat will run entirely off the battery bank, which can be deep-cycled up to 5,000 times. “Lithium-ion batteries aren’t cheap,” WhisperPower concedes, “so this system requires a considerably higher up-front investment that a conventional large generator with lead-acid batteries. But the fuel savings over the life of the system should pay for itself. In highly-regulated environments like Europe, the reduced emissions from such a system A large bank of Lithium-ion batteries are at the heart of WhisperPower’s New School system, may be essential for a vessel to meet the and are equivalent to the peak load of the boat necessary standards.”
