As the marine industry moves toward more sustainable operations, the push for large-scale vessel electrification continues to grow. A critical component in this shift is the development of Rapid Charging Systems (RCS) for electric ferries, which transfer electrical power from shore to ship quickly and efficiently.?one of the greatest challenges lies in managing the movement of vessels relative to the dock while ensuring a safe electrical connection.

From Maggie Stagner’s perspective, an electrical engineer at Elliott Bay Design Group (EBDG), one of the greatest challenges lies in managing the movement of vessels relative to the dock while ensuring a safe electrical connection.

"We have to bridge the gap between the vessel and shore safely, even as the ship is constantly moving. RCS technologies and their associated mooring systems can help us do that, but often require significant infrastructure modifications," says Maggie. Countries like Norway have been early adopters of RCS, and North America is beginning to follow suit.?

Rapid Charging Systems: A Key to Electrification?

Maggie explains that RCS technologies are critical for electric ferries with short docking periods. Systems like Cavotec's Automated Plug-in System (APS), which has been successfully deployed in Norway, and 3mar's NECTOR ramp-mounted solution are examples of how innovation can meet the industry's growing need for efficient power transfer. These systems establish connections quickly and securely, supporting the transition to greener marine operations.?

EBDG is currently working with clients such as Casco Bay Lines and Washington State Ferries to develop some of the first plug-in vessels in North America. Maggie’s role is to evaluate vessel design, dock configurations, and power requirements to provide unbiased engineering analysis and ensure that operators have the best RCS solutions available.?

Solutions and Adaptations for Charging Systems?

"The challenge of securing a stable connection while minimizing infrastructure costs is a balancing act," says Maggie. Solutions like Shore-Link’s ramp-mounted E-Ferry Charger system, which compensates for vessel movements and charges up to 5 MW, offer flexible configurations that reduce the overwhelming extent of major modifications.

Similarly, the Stemmann-Technik davit Ferry CHARGER simplifies the mooring process by providing flexible connection points through a rotating arm. Where shoreside infrastructure modifications are infeasible, charging could be developed on a mobile platform, such as EBDG’s patent pending Clean Harbor Alternative Mobile Power (CHAMP) barge.?

In all cases, these charging technologies highlight the marine industry's commitment to reducing emissions while enhancing the efficiency of operations.

Maggie emphasizes that while vessel electrification presents unique challenges, the advancements in RCS technologies offer exciting opportunities for the future of sustainable shipping.?

A Sustainable Future for the Marine Industry?

According to Maggie, the path to more sustainable shipping is clear: "As RCS technologies continue to evolve, we’ll see more vessels relying on these systems to meet environmental goals and operational efficiency." With her expertise in naval architecture and electrical engineering, Maggie is at the forefront of EBDG’s efforts to help clients navigate the complexities of vessel electrification and implement cutting-edge solutions.?
