The Submarine Safety Program ( SUBSAFE) is a quality assurance program of the United States Navy designed to maintain the safety of its submarine fleet, specifically, to provide maximum reasonable assurance that submarine hulls will stay watertight, and that they can recover from unanticipated flooding. SUBSAFE covers all systems exposed to sea ...

Subsea valves are used to isolate or control the flow of material through an undersea pipeline (submarine pipeline) or other apparatus.Most commonly used to transport oil and gas, they are designed to function in a sub-marine environment, withstanding the effects of raised external pressure, salt-water corrosion, and bubbles or debris in the material carried.
Unlike the steam engine or internal combustion engine, it has no valves or timing train. The heat source (not shown) would be placed under the brass cylinder. A Stirling engine is a heat engine that is operated by the cyclic expansion and contraction of air or other gas (the working fluid ) by exposing it to different temperatures, resulting in ...
