Abstract
Applications ranging from deep water drilling rigs and wells to in-situ seismographs and AUV recharging require subsurface electrical power. Undersea thermal vents create opportunities to generate significant levels of at-sea power. Effectively harnessed, benefits derived from subsea power sources range from increased station-keeping to persistent surveillance. Mechanical Solutions, Inc. (MSI) proposes an approach that will result in compact and durable closed Rankine cycle systems that provide electric power in deep sea environments. A single high-speed rotating machine, with oil-free, process lubricated bearings in a hermetically sealed package forms the heart of a system that will be durable, lightweight and small in size. Successful development of the MSI technology will help meet the ever-growing demand for more electric power in subsea environments. The MSI system will be maintenance-free, easy to deploy, with simple yet practical means to negate the fouling effects typically encountered in hydrothermal vents. Phase II will provide a prototype of a practical and cost-effective thermal-to-electric power conversion system. MSI"s Phase I pre-proposal analysis work included assessment of a sample cycle using a standard power fluid with good results. Phase I work will verify the feasibility of the approach against a definitive set of hydrothermal and subsea specifications.
