Connecting deep submergence systems (submarines) in the field can be a dangerous and difficult task. The rigid piping systems used today have little flexibility to accommodate for variations in connection points and differences in tolerances between vessels. Atkins & Pearce, a 200 year old textile processing company, has developed a technology that uses a multi-layered approach to create a high pressure hose that is extremely flexible. Inspired by the human body, A&P’s technology uses a braided substrate in conjunction with high strength reinforcement rings. Taking existing technology and expertise in the field of fiber science, A&P developed the innovated concept of using compression resistant coils to withstand external pressures and a braided sub-structure to contain internal pressures. A&P’s technology combines burst protection, compression resistance, flexibility, and the ability to attach to a variety of connection points. The system can eliminate unnecessary spare parts and make the job of connecting Deep Submergence Systems easier and safer. Potential civilian applications include offshore oil platforms, deep-sea science research and other underwater systems.

There are many commercially available flexible hoses for use in non-rigid coupling of hydraulic, air, and other piping systems. However, these systems are currently not designed for operating under severe hydrostatic and dynamic pressures experienced by Deep Submergence Systems in their extreme operating environments. The pipes that connect the DDS to the sub are exposed to the water and experience the full compressive force of the ocean at whatever depth the submarine goes to. This high level of external compression will cause traditional hose systems to collapse and fail. A solution is desired that can deliver the required flexibility and withstand the high levels of compression. The United States Special Operations Command published SBIR solicitation topic SOCOM08-002 entitled, "Deep Submergence Rated Flexible Hoses and Piping System Connectors." Atkins & Pearce (A&P) developed a proposal, was selected for Phase I funding, and demonstrated feasibility of their technology during a Phase I SBIR contract (H92222 - 08 - P- 0012). The Phase I feasibility effort focused one developing a technology that can withstand high pressure environments, hydrodynamic, and other forces unique to Deep Submergence Systems operating environments. The design uses high strength flexible fiber based hoses to meet the functional pressure requirments.
