New marine DC protection technology causes buzz at E&H marine expo

A record number of attendees and exhibitors came together last month at the Electric & Hybrid Marine Expo in Amsterdam to discuss the future of the marine industry. What a relief to be able to network face-to-face after the hiatus of the past few years! We were glad to have the chance to exchange information and catch up on important developments in person.

Yaskawa Environmental Energy / The Switch agrees landmark pact with Corvus Energy

Yaskawa Environmental Energy / The Switch is set to join forces with leading maritime energy storage system (ESS) manufacturer Corvus Energy to continue the development of its smart Battery Short-Circuit Limiter (BSCL) protection device for large-scale battery solutions and advanced DC power distribution.

“I didn’t know it existed!”

Such was the exclamation from at least 4 different potential customers who visited our stand at ASME in Rotterdam from June 14–16, 2022. “I’ve been looking for such a solution for the past few years – but just couldn’t find anything,” said one, coming up to the stand to start discussing our solid-rotor technology with…

‘Permanent magnet’ makes propulsion technology different

– An interview with Mr. Jonas Nyberg, Managing Director West, Berg Propulsion, and Dr. Jussi Puranen, Head of Product Line, Electric Machines, The Switch. By Zhao Bo, Journalist with China Ship Survey Although permanent magnet (PM) machines were invented more than 100 years ago, they haven’t been used in megawatt-class applications until the past few…

Dimensioning the shaft line for a shaft generator or propulsion motor

Patrik Holm If you’re considering a shaft generator or propulsion motor for your vessel design, you already know you’ll be saving on fuel consumption, improving efficiency, and complying with the current EEDI and EEXI emission limits. With an electric machine on the shaft line, we face new considerations in shaft line dimensioning. The bearings in…

Road to net zero

Reaching net zero by 2050 is perhaps the biggest challenge for humankind ever! Yaskawa Environmental Energy / The Switch has always been developing technologies and products that enable our customers to provide solutions that contribute to the journey toward net zero.

Why permanent magnet machines outperform induction machines?

A study we made during summer 2021 quantified impressive permanent magnet (PM) machine efficiencies for vessels like LNG and LPG carriers that often utilize slow-speed, direct-driven in-line shaft generators producing electrical power from two-stroke main engines.

Future tools are already here

The marine industry is looking for ways to comply with looming emission regulation deadlines and prepare for the future. Possible solutions include a host of alternative fuels, further electrification and greater efficiency of current solutions.

Are you ready for the hydrogen revolution?

Hydrogen is the fuel buzzword these days, and the landscape is changing fast. Hydrogen-fueled trains, ferries, heavy-duty trucks, cars, buses are already running in Europe and elsewhere.
