Switch tracks to DC distribution What if your next vessel could be built with dedicated all-marine DC drive train key components that would No need to wait. Our marine-specific components are proven and ready for your next vessel –simplified, optimized and uncompromised. And by getting the drives and electric machines from only one source, you’ll…

Looking at my email history, I see that the term “shaft generator” first appeared in my email conversations in May 2013. So, it has been exactly ten years to date from when we first started to think how we could utilize our permanent magnet technology originally developed for the wind industry in marine applications –…

Delivering a vessel with Dynamic Positioning (DP) classification can be challenging. And the higher the DP rating, the more difficult it can be. Luckily, there are experts delivering DP systems that can handle both the complex force calculations for the steering and the failure modes and effects analysis (FMEA) for such a complex system. But…

The Switch PMM2000s are rolling out! These giant permanent magnet machines meet the pressing need for more power and torque in shaft generator applications. The first one passed its customer string test in January 2023 with flying colors and is now on its way to the shipyard. Testing challenges all met Both the initial back-to-back…

Have you heard about our unique DC protection devices – 4 ultra-fast disconnect devices now available to safeguard marine DC electrical systems? When the marine industry faced increasing challenges with space and costs, people recognized DC would be more efficient. But new systems would be needed, and the issue of safety was a big concern.…

Since the beginning of this year, new measures introduced by International Maritime Organization (IMO) – called the Energy Efficiency Existing Ship Index (EEXI) and Carbon intensity Indictor (CII) – have taken effect. The purpose of these measures is to reduce the shipping industry’s greenhouse gas emissions on its path to achieve a net zero target.…

What does the future hold for electrification of the marine industry? A review of the past year’s trends shows a clear movement toward electrification. Green transition gathering speed The transition to using sustainable solutions in the marine market has clearly been on the industry agenda over the past year. And what’s more, our conversations with…

Early 2023 will see the first deliveries of our largest permanent magnet (PM) shaft generators to shipyards. Purpose-built for the shipping giants of the sea, the PMM2000M brings maximized torque capacity with the lowest mass and inertia to fulfill the power production needs of the very largest cargo vessels – and at the same time…

With future marine fuels as yet undecided and the looming pressure of IMO-mandated emissions deadlines, vessel designers and owners need good options. The Switch DC-Hub is a multi-source, multi-load DC system based on standardized power drive units. It offers a wide choice of power generation, energy storage, charging, propulsion power and clean power options for…

System integrators face many more complex requirements and challenges with today’s increasingly versatile and comprehensive systems for propulsion and the production of onboard electricity. As a result, system integration must now start much earlier. This means information on system components must be available earlier, especially in the case of unfamiliar new technologies and solutions that…
