UC San Diego’s Scripps Institution of Oceanography today announced that naval architecture and marine engineering company Glosten has been selected as the naval architect for the university’s new California coastal research vessel (CCRV). The new vessel will be an innovation in the maritime industry with a first-of-its-kind hydrogen-hybrid propulsion system.

With this selection, Glosten will provide the preliminary design, contract design, and detailed design for the research vessel to be operated by Scripps Oceanography. Glosten is a consulting firm of naval architects and marine, electrical, production, and ocean engineers with expertise in providing design and engineering support to the oceanographic research community. The firm was selected after participating in the university’s request for proposal process.

“This vessel will be the first of its kind, and the selection of the naval architect is a major milestone for Scripps,” said Bruce Appelgate, associate director and head of ship operations at Scripps Oceanography. “Fundamentally, our ships have to be reliable and capable in order to support the innovative research our scientists conduct at sea. On top of that, the ship we envision needs to demonstrate that zero-emission power systems work effectively under demanding real-world conditions. It’s the job of the naval architect to provide the necessary engineering, design, and integration skills needed for this project to succeed on every level.”

California legislators allocated $35 million towards the design and construction of this vessel last summer. When complete, the vessel will serve as a platform for education and research dedicated to understanding the California coast and climate change impacts to the coastal ecosystem.

The hybrid-hydrogen design of this new vessel represents an innovation in the maritime industry. Currently, emissions from diesel engines on ships contribute to greenhouse gases and pollution. Development of this and subsequent zero-emission vessels is essential to the University of California’s Carbon Neutrality Initiative, the goal to be carbon neutral by 2025.

This new vessel will feature an innovative hybrid propulsion system that integrates hydrogen fuel cells alongside a conventional diesel-electric power plant, enabling zero-emission operations. The design is scaled so the ship will be able to operate 75 percent of its missions entirely using a non-fossil fuel—hydrogen—with only pure water and electricity as reaction products. For longer missions, extra power will be provided by clean-running modern diesel generators. The vessel represents a major step in advancing California’s pledge to reduce global climate risk while transitioning to a carbon-neutral economy.

The proposed 125-foot vessel will be equipped with instruments and sensing systems, including acoustic Doppler current profilers, seafloor mapping systems, midwater fishery imaging systems, biological and geological sampling systems, and support for airborne drone operations. These capabilities, along with state-of-the-art laboratories, will enable multidisciplinary research, advancing our understanding of the physical and biological processes active in California’s coastal oceans. This new vessel will be dedicated to California research missions, with the capability to study issues vital to the California economy such as the health of marine fisheries, harmful algal blooms, severe El Niño storms, atmospheric rivers, sea-level rise, ocean acidification, and oxygen depletion zones.

Scripps Oceanography has worked with Glosten previously, initially more than 60 years ago on the design of Research Platform FLoating Instrument Platform known as FLIP. Glosten was also involved in the midlife refit of R/V Roger Revelle, a $60 million renovation that advanced the scientific capability and service life of Scripps’s largest ship.

The anticipated schedule for design and construction of the hydrogen-hybrid research vessel includes one year to complete the basic design. Following U.S. Coast Guard approval of the design, the university will select the shipyard where the design will be constructed. Construction and detail design will likely take an additional three years.

When completed, it will join the fleet of vessels managed by Scripps including the Navy-owned research vessels Sally Ride and Roger Revelle, which conduct global oceanographic research, and the R/V Bob and Betty Beyster, a nearshore scientific workboat. All research vessels are stationed and maintained at the university’s Nimitz Marine Facility in Point Loma.
