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…
‘Permanent magnet’ makes propulsion technology different
The April issue of China Ship Survey magazine published a five-page article about permanent magnet technology used in the propulsion application. Entitled “‘Permanent magnet’ makes the propulsion technology different,” the article covers the following main topics: Permanent magnet (PM) technology as a simple and efficient solution The importance of joining forces to collaborate and innovate…
LNG and beyond: box ships’ path to decarbonization
On April 13, Jussi Puranen was one of the panelists at Riviera’s Container Ship Tech & Ops Webinar Week. As one of the three panelists, Jussi discussed the potential for fuel savings in container vessels by using permanent magnet shaft generators as one of the ways to meet decarbonization targets. He highlighted the efficiency advantages…
New test center verifies large marine electrical drives
Panu Kurronen Marine engineers, investors and builders are in a tight spot these days. There’s the pinch of approaching regulation deadlines and the stress of using new technology rather than familiar, well-tried equipment. We understand. Change is costly and stressful. We’ve been exploring and expanding PM machine technology for two decades, first for wind power…
LNG and beyond: box ships’ paths to decarbonizations
On Wednesday, April 13, Yaskawa Environmental Energy / The Switch took part in the Container Ship Tech & Ops Webinar Week organized by Riviera Maritime Media. LNG and beyond: box ships’ paths to decarbonization From LNG and LNG-ready to bio-LNG, ammonia-ready, methanol and fuel saving technologies, container operators are considering an expanding range of fueling…
Solving marine DC distribution, selectivity, redundancy and safety issues
Teemu Heikkilä The marine industry is evolving rapidly to meet 2023 IMO-mandated emissions deadlines – and the ones to follow. To accomplish this, long-established methods and equipment are being reevaluated, upgraded or replaced. Making DC distribution the best choice for marine use Power distribution is a promising area for vessel efficiency gains. Although AC distribution…
How hybrid systems offer propulsion optimization
Asbjørn Halsebakke talks with Motorship’s Wendy Laursen about how hybridization does not in itself change propulsion choices, but it does offer opportunities for design optimization.
