Title:  Advanced Emergency Leak Arresting Technology
Research & Technical Areas:  Materials/Processes

Acquisition Program:  PEO Ships, PMS 400D, Aegis New Construction Program, ACAT 1
  Objective:  Develop a device that can be rapidly applied and instantaneously seal water, gas, or petroleum based products leaking from shipboard piping systems of a variety of configurations while under pressure.
  Description:  The current US Navy emergency pipe patching and plugging procedure requires a multitude of different techniques to combat different leak situations. With the technology currently available, each pipe rupture scenario requires securing of the leak source as well as the use of highly trained individuals and cumbersome equipment. In most cases, more than one person is required to effectively control and repair the leak in a timely manner. When there are jagged or deformed edges or nonlinear pipe configurations involved, all of the US Navy patch repair kits currently available become ineffective. This topic seeks to explore the development and application of a universal pipe patch system that will simplify and expedite the pipe patching process. The ideal solution would be a system that is capable of immediately stopping leaks in pipes ranging from ½” – 12” in diameter, constructed from a wide variety of metals and composites. The innovative new system would have the ability to immediately seal all water or petroleum based liquid leaks and steam or gaseous pipe leaks while under pressure. The universal new system should meet or exceed the pressure and temperature limitations of the current multitude of US Navy pipe repair devices. The desired new product should have the ability to be applied with or without securing the leak source and should not subject the sailor to possible injury. The final product shall be fire resistant and continue to operate effectively while submersed. The device shall not be cumbersome in nature and be readily deployable using minimal manpower to dispatch and install. This single pipe patching solution shall work effectively on rough jagged surfaces, all pipe elbows, pipe tees, valves, and other pipe configurations currently used in US Naval shipbuilding with no pretreatment required. This device should be rugged enough to withstand storage aboard a US Navy Ship and have a shelf life of not less than 5-years.

  PHASE I: Demonstrate the feasibility of an advanced leak arresting system. Identify suitable candidate materials, equipment(s), and manufacturing processes and methods of installation anticipated to enable the developed and deployment of the proposed system. Establish performance goals and metrics to analyze the feasibility of the proposed solution. Develop a test and evaluation plan that contains discrete milestones for product development for verifying performance and suitability. Create required sketches and drawings to demonstrate the concept of operation.
  PHASE II: Develop, demonstrate and fabricate a prototype as identified in Phase I. In a laboratory environment, demonstrate that the prototype meets the performance goals established in Phase I. Verify final prototype installation methodologies in a representative laboratory environment and provide results. Develop a cost benefit analysis and a Phase III testing and validation plan. Create an installation training video and a device maintenance and storage guide.

  PHASE III: Construct a full-scale prototype based on the Phase II results for testing in a shipboard environment. Working with government and industry, demonstrate onboard a selected DDG 51 class hull and conduct extended shipboard testing. PRIVATE SECTOR COMMERCIAL POTENTIAL/

  DUAL-USE APPLICATIONS: Potential commercial applications include all classes of U.S. Naval and Commercial ships and land based manufacturing/utility plants. An effective emergency pipe patching and repair system would be applicable to any building or structure that have a multitude of piping systems.

Questions and Answers:
Q: Our technique to carry out efficient pipe rupture repair involves having Liquid Nitrogen available at the time. This would mean that Navy ships, to use the method, would have to have the cryogen there on a continuous basis.

1. Is it the case that ships carry LN? or would this have to be a new practice were this practice?

2. And, adding LN fire control as well, be adopted for the fleet by the US Navy?
A: 1. No. New Practice.

2. There is no work going on in the USN to add LN fore protection to a USN ship.
