Advanced Structural Watertight Door System Navy SBIR FY2005.2 Sol No.: Navy SBIR FY2005.2 Topic No.: N05-133 Topic Title: Advanced Structural Watertight Door System Proposal No.: N052-133-0241 Firm: Juniper Elbow Company, Inc. 72-15 Metropolitan Avenue Middle Village, New York 11379 Contact: Elliot Wiener Phone: (718) 326-2546 Web Site: www.juniperindustries.com Abstract: New naval ship designs will result in faster & lighter vessels manned by fewer sailors. These design changes necessitate weight savings, reduced maintenance time, and life cycle cost reductions in all shipboard components. The objective of this project is to develop a new and improved watertight door system for future and existing ships that meet these requirements. Juniper Industries has been a primary supplier of standard navy watertight doors for several decades. Here, we propose to team with Walz & Krenzer, Inc. to focus on improving the primary areas of concern on all existing standard navy watertight doors, namely the the weight, the dogging system, the sealing system, the hinging system, and the life-cycle costs. The result will be watertight doors that are lighter, more durable, require less maintenance,and that are fully watertight. In addition, it is anticipated that the new door system will have the capacity to be used with a variety of panel materials, increasing the potential for both navy and commercial watertight door applications. Phase 1 research will demonstrate the economic and technical feasibility of two new dogging, hinging, and sealing systems, as well as investigating the use of composite door panels. Benefits: Both the military and commercial shipbuilding markets will welcome lighter, less expensive, and more durable watertight doors. High speed, lightweight commercial passenger vessels and ferries will benefit greatly from lighter weight watertight doors. Doors that require less maintenance and that retain their watertight integrity ensure the safety of passengers and crew aboard all types of vessels. Return
