LIBERATORE, DJBASKERVILLE, JELCdr. Donald J. Liberatore
USN: began his career in the U.S. Navy in 1965. He has had many diverse assignments involving surface ships and submarines during the past seventeen years. During his tour at Naval Shipyard Portsmouth (N.H.) he was Assistant Design Superintendent and responsible for the introduction of Heat Recoverable Coupling technology into the shipyard. Presently he is assigned to the Naval Sea Systems Command (NAVSEA) in the Sonar Dome Office. Prior assignments within NAVSEA have been as Assistant Ship Systems Design Manager for the SSNX and FA-SSN preliminary designs in the Submarine Propulsion Analysis Branchin the Submarine Hydrodynamics Branchand in the Gear
Coupling and Clutch Branch. He received his Bachelor of Engineering degree from Vanderbilt University in 1971 and in 1977 graduated from Massachusetts Institute of Technology with his M.S. degree in Naval Architecture and Marine Engineering and his Professional degree of Ocean Engineer. A member of ASNE since 1975 LCdr. Liberatore also is a member of IEEE SNAME the Naval Institute and Sigma Xi. Cdr. James E. Baskerville
USN: is presently assigned to NAVSEA as the Ship Manager for the DDG 51 the Navy's next generation surface combatant. In a previous tour at Naval Shipyard Pearl Harbor he was the Navy's Program Manager for Heat Recoverable Coupling introduction in ship repair and maintenance. A graduate of the U.S. Naval Academy Class of 1969 he is a qualified Surface Warfare Officer and a designated Engineering Duty Officer (ED). He received his M.S. degree in Mechanical Engineering and his Professional degree of Ocean Engineer from Massachusetts Institute of Technology and also holds a patent right on an Electronic Control and Response System. His naval assignments have included tours in the USS Ramey (FFG-2) as Aide and Flag Lieutenant to the Commander
Naval Electronic Systems Command and as Ship Superintendent
Surface Type Desk Officer and Assistant Design Superintendent at Naval Shipyard Pearl Harbor. Cdr. Baskervi

Although Heat Recoverable Couplings (HRCs), used to join pipe, may be labeled innovative “state-of-the-art” technology for U.S. Naval Shipyards, they have been in use in foreign ships and high technology industries for over a decade. HRCs provide a permanent leak-proof pipe joint in specified applications without the use of high temperature and the inherent hazards of an open flame. Manufactured from NITINOL, a nickel-titanium alloy developed by the U.S. navy, the couplings exhibit a “shape memory” characteristic. That is, they return (shrink) to a specified shape (pipe diameter) thus forming a mechanical seal when the expanded coupling is removed from a cryogenic environment and warmed above approximately —130°C. This paper provides background information into the development of NITINOL, technical explanation of shape memory metallurgy, and a summary of results, with specific examples, describing the trial use of HRCs at Pearl Harbor and Norfolk Naval Shipyards. Limited return cost data and recommendations for future use are presented. Then, using the HRC Program as a basis, the Authors discuss the conservative nature of the ship repair and maintenance environment. This environment, in the Authors' opinion, couples with complex contractual constraints and requirements which serve to restrict the introduction of new ideas. An analogy is made to Russian tenacity of recent years which promotes “exploring and doing” while we in the U.S. navy are frequently content to study.

Ship design directions are towards closure of net design objectives in surface warships on direct measures of combatant capabilities. Simulation techniques are employed to model design conditions encompassing the dynamics of the ship system including its human action network; of the system environment; and of threat stresses. Capability objectives can then be evaluated in traceable relationships to working level design parameters of the mechanical system (“ship”), hardware, and software, as modified by system-level variables. This paper describes the technical rationale which underlies the initial development of the prerequisite methodology in application to a surface warship taken from the waterline up. This application is dominated by the large class of system dynamics known as EM effects. Hence, the relationship of the general case to the particular area known as EM Effectiveness is considered.
