Seaspan Ferries Corporation is proud to announce that it has reached an agreement with Corvus Energy, of Bergen, Norway and Vancouver, Canada, for the first delivery of Corvus’ Blue Whale ESS, to be installed onboard one of their cargo ferries.

Blue Whale is a new large-scale energy storage system (ESS) – a groundbreaking battery system designed for large ships with high zero-emission energy demand, such as cruise ships, large Ro-Pax and Ro-Ro ferries, and cargo ships. Its unique rack-free design of stacking modular blocks provides the industry’s highest volumetric battery room energy density and, consequently, maximizes a ship owner’s passenger or payload opportunities.

For its inaugural field trial, the Blue Whale battery system will be installed on board Seaspan Reliant, a roll-on/roll-off drop-trailer cargo ferry built in 2016 that sails the Salish Sea multiple times a day, with terminals and service between B.C.’s Lower Mainland and Vancouver Island.

The Blue Whale ESS will replace an in-service first generation Corvus AT6500 ESS in the existing battery room, increasing the vessel’s energy storage capacity from 545 kWh to 1892 kWh.

“Seaspan Ferries is committed to caring for the environment, and this is an exciting opportunity to play a role in the transformation of shipping towards a greener and more sustainable industry,” says Gord Miller, VP Seaspan Ferries. “This trial will also provide valuable experience locally, as personnel from VARD Marine, BC Hydro and the University of British Columbia will provide integration design, shore charging from the grid infrastructure, and engine efficiency studies respectively—all important areas of expertise to develop as British Columbia develops its coastal emissions reduction plans.”

“The increased battery capacity will give us operational flexibility to enhance service levels while reducing emissions and fuel consumption,” says Harly Penner, Director of Fleet Renewal and Maintenance at Seaspan Ferries. “We are excited to partner with Corvus again. They have been outstanding collaborators in our quest towards decarbonization through fleet hybridization and electrification.”

Installation of the new Blue Whale system is scheduled for Summer 2021, at which time Seaspan also plans to relocate the AT6500 system onto sister vessel, Seaspan Swift.

“Seaspan has been an important partner for Corvus Energy. They were amongst the first to install our batteries in North America. Their extensive experience on our battery systems and knowledgeable team makes them the ideal field trial partner,” says Sean Puchalski, EVP Strategy & Business Planning at Corvus Energy.

“Although Seaspan Reliant is a relatively small vessel for a Blue Whale system and the retrofit will be done on a very tight schedule, the challenging conditions make it ideal for a trial site,” says Richard Wing, Chief Research & Development Officer at Corvus Energy. “Moving and situating the Blue Whale modules and pack controllers into the existing battery room will also test and validate the materials handling equipment and service tools we have developed. Moreover, during this time of restricted travel, being able to conduct the field trial in the same location as our Canadian development and manufacturing facilities is a huge benefit and allows us to stay on schedule for commercial product release.”

Blue Whale commissioning and trials will be carried out while the vessel is in full-service operation during the remaining months of 2021. With three and a half times the previous energy capacity, Seaspan will be able to expand the use of battery power beyond spinning reserve to also provide fuel-efficient peak shaving, load balancing, and even zero-emission operation on battery power only.

Once installed, performance data from the ESS will be collected automatically, analyzed and monitored remotely through Corvus’ cloud-based monitoring and optimization system, providing valuable feedback to the R&D team.

Seaspan is grateful for the generous support provided to both Corvus and Seaspan by Canada’s Ocean Supercluster, an initiative of Innovation, Science and Economic Development Canada. The field trial is an important pre-commercial activity that enables the development team to validate requirements for a high-volume robotic production line and a range of complex post-production processes.

The Blue Whale field trial and all key maritime authority certifications are expected to be completed by Spring 2022, at which time commercial deliveries will commence.
