China Aviation Lithium Battery (CALB) has made history by becoming the first Chinese company to receive Type Approval certification from the American Bureau of Shipping (ABS) for its marine lithium-ion battery system.

The certification follows successful sea trials of CALB's advanced battery system aboard the Karan8 hybrid offshore support vessel, developed for Saudi Aramco. The entire project—from initial design to final delivery—was completed in just 60 days, demonstrating CALB's rapid engineering and manufacturing capabilities.

The ABS-certified system meets rigorous international safety standards, featuring an intelligent liquid cooling thermal management system and redundant safety protocols to ensure reliable operation in demanding marine environments. Its ultra-fast charging capability and multi-layer protection systems set new benchmarks for hybrid vessel power systems.

Notably, this achievement comes after CALB previously secured DNV's Type Approval for its marine battery technology. The dual recognition from two of the world's top three classification societies (including Lloyd's Register) confirms CALB's compliance with the most stringent marine safety standards, including ABS Guide for Batteries and IMO requirements.

Classification societies like ABS, DNV, and Lloyd's Register play a critical role in maritime safety, establishing technical standards and certifying marine equipment worldwide. CALB's certifications validate the company's ability to meet these global benchmarks while supporting the industry's transition toward electrified and low-carbon maritime operations.
