newGear Safe, pressure-tolerant Lithium-Ion Subsea Battery System powers Innovative under-Ice rOV Advanced Testing Offers More Validation for SeaSafe Modules, BMS SAfE, RELIABLE, LoNGLASTING BATTERy PoWER for the deep subsea is a game changer. Proven battery management solutions in pressure-tolerant, tested subsea batteries can enable AUVs and optically tethered ROVs to master deep and remote oceanographic research previously unachievable, as well as unlock mysteries in the ocean depths, or even under ice caps. Offshore oil and gas production can now safely reach beyond the limits of traditional battery systems. The day is here when engineers can plan and implement subsea production systems in deeper locations that are continuously monitored and thus safer, using more reliable operations and safety mechanisms than previously available. The bottom line is that new technological battery solutions can help make offshore oil and gas more accessible and affordable. 42 UnderWater july/august 2014 SouthWest Electronic Energy (SWE), based in Missouri City, Texas, successfully tackled the challenges of how to safely provide higher peak electrical power that previously was only available in the old technology of sealed lead-acid (SLA) battery technology. SLA's 1900 technology is too heavy and too big and does not last long enough to meet current subsea challenges. SWE pioneered, researched and developed SeaSafe, a battery solution that delivers breakthrough safety, reliability and configure-to-order f lexibility. SeaSafe Smart battery solutions are proving they are poised to change the game in subsea applications, enabling electric-powered monitoring, sensing, propulsion and feedback control for more efficient, precise and reliable subsea operations. Other market segments such as automobiles, medicine, military, consumer and industrial products have migrated to lithiumion batteries. Now, a range of modern subsea applications requires lithium-ion solutions. For example, deep-sea oil and gas operations need more precision and long-life sensors and monitors. Manned Underwater Vehicles require safe operation, deeper dives, longer observation times and lighter weight. ROVs, whether they are hybrid or data tethered, require electric-powered motors, manipulators, high voltage, high power, light weight and smaller volume power. AUVs need longer survey runs, deeper dives and lighter weight. To meet these subsea application challenges, SWE has introduced breakthrough subsea-ready battery components to enable solutions: SeaSafe Smart Autonomous Battery Modules, SeaSafe Pressure Equalization Cases, SeaSafe Observer Software, and SeaSafe Parallel Integrator Isolators. SeaSafe incorporates SWE lithium-ion and a patented battery management system to deliver best-in-class safety and reliability that is autonomous. Successful Testing Provides Validation The SeaSafe Battery Module successfully passed 10,000-pounds-per-square-inch (psi) pressure testing, achieving an industry milestone for SWE and developers of subsea vehicles and infrastructure. Over several years of testing, eight separate pressure tests were completed, mainly at the Southwest Research Institute (SWRI), an independent research laboratory in San Antonio, Texas. The SeaSafe battery system in a 316 stainless steel case was lowered into a pressure chamber to undergo hyperbaric pressure testing. The exhaustive hyperbaric pressure test conducted in SWRI's
