Title

Development of a Non-Explosive Ship Shock Testing System 

Abstract

Presently, at-sea ship shock tests subject the vessel to high-pressure pulses created by detonating large explosive charges in the open ocean. The process is highly disturbing to the environment and subject to a variety of operational restrictions. The results are severe costs and scheduling constraints. Legal challenges due to increasing environmental concerns are driving costs upward and may potentially prevent the Navy from performing this vital testing. DYNAFLOW INC., teamed with APTI and Anteon Corporation proposes to leverage previous research efforts to develop a completely non-explosive technology that will enable ‘in-situ’ shock testing in an enclosed facility such as a dry-dock or wet slip. This technology can also be applied to an open water near shore environment through the use of appropriate pressure mitigation techniques. 

Benefit

The concept, “DockShock”, involves employing an array of proprietary electrically initiated pressure sources that produce pressure pulses sufficient for full ship shock testing. Because these pulses are directed, only a small fraction of the open ocean energy is necessary to deliver the equivalent shock impulse. Consequently, an enclosed facility can be modified with protective measures to insure that the dock or surrounding structures are not damaged. The benefits include: · Environmental – eliminates unnecessary damage to ocean wildlife. · Cost – substantial savings achieved by eliminating at sea costs and time. · Flexibility – testing schedule no longer driven by weather and seasons.
