C-Power has announced it will commence a six-month sea trial in partnership with the US Department of Energy and US Navy, to test and validate the technical and economic capabilities of its SeaRAY autonomous offshore power system (AOPS).
Initially conceived during a US Department of Defense project, the SeaRAY autonomous offshore power system (AOPS) provides in-situ power, energy storage, and real-time data and communications support that will advance the marine economy toward a future of autonomous, connected and resident technologies, C-Power said.
It is designed to support unmanned offshore activities, including subsea vehicles, sensor packages and operating equipment. The system supports a range of potential applications that will spur innovation in critical industries such as defense and security, offshore energy, aquaculture, and science and research, according to a press release.
“The ocean is a power desert. Providing reliable power and real-time data communications through an AOPS is critical to unlock the full potential of the marine economy,” said Reenst Lesemann, chief executive officer of C–Power.
“The SeaRAY delivers these capabilities and enables a future of cheaper, safer, cleaner, more connected offshore operations. We are excited to work with our federal partners at the DOE and Navy, as well as our technical partners on the trials, which are key steps toward delivering the SeaRAY AOPS to the market.”
The sea trials will begin later this year at the Navy’s Wave Energy Testing Site (WETS), located off Marine Corps Base in Hawaii on the island of Oahu.
The SeaRAY AOPS at WETS is a moored configuration consisting of a surface wave energy converter; a single, combined mooring, data, communications and power cable; and a seafloor base unit that provides 100kWh of energy storage for payload operation.
The SeaRAY, which will support several payloads during the deployment, has been developed under a $3.2 million DOE-sponsored research and development programme.
The SeaRAY AOPS is scalable to capacities from tens of watts to tens of kilowatts. The AOPS is designed to survive the expected conditions of a 100-year storm off the Oregon coast and is easily transported worldwide in two standard ocean containers.
C–Power’s technology partners for the sea trials include EC-OG, RigNet, EOM Offshore and Saab Group.
“Saab is leading the industry toward achievement of autonomous residence, which is an absolute market requirement for delivering reduced carbon emissions, lower costs and increased capabilities,” said Peter Erkers, sales director for underwater systems at Saab Dynamics AB. “The SeaRAY provides the key operational support — power generation, energy storage and real-time communications capabilities — that enables system residency. C-Power’s AOPS is the missing piece of the puzzle.”
The SeaRAY’s seafloor base unit will be provided by EC-OG. EC-OG’s 100kWh Halo lithium-ion battery energy storage system is designed for the harsh subsea environment and will be fully integrated with the AOPS, providing the payload interfaces for power, data and communications.
After successful completion of the WETS sea trials, C–Power expects to complete commercial launch of the SeaRAY in 2021.
