Subsea Power Supply Based On Submarine Propulsion Technology

摘要

The paper reports on the development of electrical subsea power generation and storage systems based onrnnon-nuclear air independent submarine propulsion technologies. Proven submarine technology representsrna promising base for innovative and high-performance subsea solutions. Reliable and cost efficient electricrnpower supply can be regarded as one of the most important factors for the successful development andrnoperation of future subsea facilities. Long step outs, large water depths and remote locations withoutrntopside infrastructure pose challenges to cable based solutions. Submarine technologies can help tornovercome these issues. Within the scope of the paper, an overview of conventional (non-nuclear) militaryrnsubmarine propulsion technology and its perspectives to be applied for civil subsea power supply systemsrnis given. The outlined technologies include diesel-electric propulsion, lead and lithium ion batteries, andrnair independent propulsion (AIP) systems. For the latter, fuel cells and closed cycle diesel systems arerndescribed. The present work highlights the potential of such technologies to be applied as an energyrnsupply for subsea systems. A modular concept is presented which is applicable for water depths up torn3000 m. It consists of battery components to satisfy large intermittent power demands as well as AIPrnmodules which will be able to offer moderate base loads. This way, tailored hybrid battery/AIP solutionsrncan be created which fit the needs of specific stationary and mobile subsea appliances. The concepts canrneasily be scaled in power and energy.
