Recently, the first SPP40 platform supply vessel equipped with SETH’s containerized power supply successfully completed its trial voyage, marking a new milestone in green marine propulsion technology. During the trial, SETH’s technical team collaborated closely with the ship owner and inspection agency to ensure a smooth and seamless process.

As a new-generation eco-friendly PSV, the SPP40 incorporates a replaceable containerized lithium iron phosphate battery system independently developed by SETH into its electric propulsion system design. With a battery capacity of 1,935 kWh, the system balances flexibility and high efficiency. It operates on a hybrid mode combining diesel-electric power with new energy batteries, retaining the energy efficiency advantages of traditional electric propulsion while integrating the rapid response capabilities of battery systems. This dual approach enhances both the vessel's overall energy efficiency and electrical safety. Its core functions include:

• Black-out Prevention: The battery can respond swiftly when encountering a sudden generator failure, ensuring continuous power supply to the grid.
• Dynamic Support: Capable of absorbing fluctuating power caused by sudden load changes or abrupt propeller load application/removal.
• Peak Shaving: Optimizes generator load to ensure operation within the most efficient and economical range.
• Zero Emissions in Ports: Supports pure battery mode, enabling zero-pollution operations during port stays.

Previously, SETH had obtained the world's first type approval certificate for a containerized power supply from Bureau Veritas (BV). Up to now, through robust technological breakthrough capability, SETH has achieved comprehensive coverage of its self-developed battery pack (S-Pack) (with modules compatible with brands such as CATL and EVE Energy), containerized power supply (S-Container), and the full range of BMS battery management system products. All these products have successfully obtained type approval certificates from two leading classification societies—the China Classification Society (CCS) and Bureau Veritas (BV)—pioneering an innovative "battery system+" marine propulsion solution.

Innovative technological breakthroughs such as the "S-DE + Battery System" and the "S-Shaft + Battery System" have opened up broad prospects for the green development of ships, laying a solid foundation for SETH to further deepen its presence in the domestic and international green shipping markets.
