“The seismic company has recently expanded its fleet of autonomous underwater vehicles (AUVs), while also noting its progress in battery technology. In November, Ocean Infinity said it had reached a milestone in battery technology for AUVs, in partnership with Kraken Robotics.

The improved batteries increase possible survey range for an AUV to nearly 700 km, with the vessels able to operate for more than four days without a charge. This has effectively doubled their endurance and capacity, a company official said.”
