Subsea Electrification: Subsea Power Evolves
are getting smarter and going untethered…and untethered subsea operations require batteries that are safe, smart, provide more capacity, deliver more power, are smaller and lighter, longer life, and highly reliable.For years, most electrical subsea operations were tethered, powered by umbilicals, which are costly, constraining, and require significant lead time. Untethered subsea vehicles used sealed lead acid, which made them heavy and bulky, or batteries contained within 1 atmosphere pressure vessels, which can be expensive and heavy.Six years ago, Southwest Electronic Energy Corp&rsquo

We are just touching the surface.”The ConceptAt the moment, subsea oil and gas systems are electro-hydraulic. Each power consumer is fed with power and communications via separate umbilicals from a topside variable speed drive (VSD). Such a system has limited flexibility, should an operator want to add in a new well or a subsea pump.The subsea power grid concept, however, would involve a single power line to the seabed equipment (in up to 3,000m water depth at present), potentially
