Battery and Pressure Vessel Makers Partner at Oceanology 2026

Leading battery manufacturer Ultralife Corporation will be exhibiting at Oceanology International London from March 10-12 at the ExCel centre. On Stand L610, Ultralife will offer live demonstrations of its subsea battery packs. Meanwhile, its experienced technical team will also be available to discuss power solutions for oil and gas applications such as Logging While Drilling (LWD) and Measurement While Drilling (MWD), as well as pipeline inspection gauges (PIGs).

The SeaSafe Endurance battery module is an easy-to-configure battery system designed specifically to fit inside pressure vessels. Recently upgraded to provide 12 per cent more capacity, it can support long-duration missions and is suitable for applications including autonomous underwater vehicles (AUVs), unmanned underwater vehicles (UUVs), oil and gas applications and oceanography equipment.

SeaSafe Endurance will be on display at two stands: on Ultralife’s stand behind the exhibitor lounge, and near the main entrance, where Prevco Subsea Housings will be displaying pressure vessels containing the battery on its stand (D30).

"The SeaSafe Endurance battery appealed to us because each battery fits neatly into half of one of our pressure vessels," explains Stephen Ashley, technical sales manager at Prevco Subsea. "Where more power is required, another battery can be placed on top to fill the vessel, or additional batteries can be placed in adjacent vessels and connected. Also, the batteries are available in 24V, 30V and 37V configurations, and can be connected in series or parallel, allowing them to support a wide range of voltage and power requirements of vehicles or equipment."

"Prevco is an ideal partner for us because the SeaSafe Endurance battery requires a pressure vessel for underwater use," added Leon Adams, VP of Sales and Marketing at Ultralife. "Prevco manufactures vessels out of a diverse range of materials, from PVC and Aluminium to Titanium Grade 5 or AL7075, allowing them to support everything from shallow-water observation ROVs or monitoring equipment to deep-sea exploration AUVs."

Ultralife will also showcase pressure-tolerant subsea battery modules that can go as deep as 6,000 meters without a pressure vessel. These are SeaSafe Direct, which can be placed directly in water, and SeaSafe II, which is suitable for use in pressure-balanced oil-filled cases. These battery modules are essentially modular building blocks for battery systems, meaning operators can easily connect them in series or parallel to provide the required voltage or capacity/current. Furthermore, all SeaSafe batteries offer four-times longer run-time compared to sealed lead acid (SLA) batteries, and 100 per cent condition-based and safety monitoring with an integrated battery management system.

In addition to these subsea battery modules, Ultralife offers end-to-end, mission-critical power for oil and gas customers that combines primary battery cell manufacturing, custom rechargeable and non-rechargeable battery packs, pressure-tolerant subsea systems, downhole (MWD/LWD) and pipeline inspection power, and hazardous-area certification support. It also offers full lifecycle services, covering everything from design and manufacture to testing, compliance, application support, and product recycling. Visitors to the Ultralife stand can see how the company’s power solutions are serving the needs of subsea and oil and gas companies globally.
