Some fairly radical changes to the naval ship design process occurred during the 1970s. The decade of the 80s has also witnessed a steady stream of changes. One of the most significant was the establishment of the Ship Characteristics Improvement Board (SCIB) in the Office of the Chief of Naval Operations (OpNav), and the resulting influence on the dialog between the military requirements decision makers and the Navy's ship designers. Other changes have occurred for which the impacts are less clear. These include establishment of the chief engineer of the Navy (ChEng) position, creation of the Space and Naval Warfare systems Command (SpaWar) and OpNav's “Revolution at Sea” initiative. This paper will describe and discuss these and other changes, and comment on the resultant impact. The authors will attempt to present a global view of the total pattern of changes and try to discern if we are on a path of revolution, or merely normal evolution.

This paper presents improvements in logistics support of hull, mechanical, and electrical (HM&E) components through standardization to the piece part level. The process of component standardization is outlined and compared with traditional HM&E acquisition approaches. The impact of standardization on logistics support is presented with case examples cited to graphically demonstrate how logistics improvements are derived. The paper also presents standardization costs and benefit analyses. A compelling case for increased HM&E standardization efforts is made from a logistics improvement perspective.

The small-waterplane-area-twin-hull (SWATH) ship has long been recognized as a promising high performance ship because of its superior seakeeping characteristics as compared to the conventional monohull or the catamaran ship. Over the years, many advancements in prediction methods for motions and wave loads of the SWATH ship have been published. Using this knowledge, a computational procedure for predicting structural load and response of the SWATH ship was developed and is presented here. The analytical method for wave load determination is based on a linear seakeeping theory where hydrodynamic interaction between the twin hulls has been included. The structural response of a SWATH ship can be calculated by using finite element models and hydrodynamic pressure distributions along the ship hulls. A correlation study has shown good agreement between calculated results and model test data of a 3,000-ton SWATH ship in motions and loads, indicating that the analytical approaches could be used in assessing the seaworthiness and structural adequacy of SWATH designs. To demonstrate the computational procedure, a case study of a T-AGOS 19 SWATH ship in sea state 7 was carried out. The calculated results of motions, loads, deflections, and stresses are presented and discussed. However, the fatigue life of the vessel has not been investigated in this paper.

The design of the new 108-ft yard patrol craft (YPs) for the U. S. Naval Academy is described from its beginnings as a senior midshipman design project, through its preliminary and contract design development at the U. S. Navy's small craft design team headquarters, Naval Sea Combat systemsengineering Station, Norfolk, Virginia (NAVSEACOMBAT-SYSENGSTA-Norfolk). During preliminary and contract design the Naval Academy Hydromechanics Laboratory (NAHL) provided experimental data to support NAVSEA-COMBATSYSENGSTA-Norfolk's design analyses in powering, seakeeping, and maneuvering. Several tradeoff studies of interest to patrol craft designers are presented. Major events in the detail design and construction of the first boat are described from both the designer's and the shipbuilder's points of view. The launching, builder's and sea trials of the first boat are described.

The uncontrolled proliferation of flammables and combustibles aboard ship, in addition to posing an obvious fire and explosive hazard, has seriously degraded the survivability and increased the vulnerability characteristics of U.S. Navy surface ships. This problem for the most part has been superficially attributed to a widespread shortage of flammable and combustible stowage capacity. As a result, current solutions have been limited to increasing stowage capacity through additional storerooms and development of more efficient stowage aids. Unfortunately, these solutions simply address the symptoms, are of a corrective nature, and do not eliminate the fundamental causes of the problem. The paper conducts a more systematic and comprehensive investigation into identifying and resolving the flammable liquids problem by considering it from a ship life cycle perspective. In this way, the problem is shown to be the resultant accumulation of a number of causes which occur during a ship's design, construction, and operational phases, and which collectively manifest themselves as a major shortage of flammable and combustible liquid stowage space aboard current fleet ships. Actions are then formulated to eliminate or counteract these fundamental causes, and validated by application to a hypothetical case study.

In 1980, at the Ship systems Technical Symposium in Cherry Hill, New Jersey, a paper was presented entitled “Reliability of Shipboard Elevators — Is There Hope for Improvement?” It painted a bleak picture of elevators and their future. The history of Navy cargo/weapons elevator installations does reveal a wide variety of equipment sizes and con figurations developed by numerous vendors working to different performance specifications for each contract. The result has been poor reliability, a proliferation of spare parts requirements, and logistic and maintenance nightmares. To correct this, NAVSEA has initiated various efforts, including a program to develop and test improved, standardized designs. The improvements expected by that program include standard capacities and speeds, lightweight construction and easy removability for maintenance. This is being accomplished through standard drawings and detailed, as opposed to performance, specifications. But the key to the success of this effort is to design and test for reliability, maintainability and safety. This is being accomplished by following NAVSEA Quality Assurance Plan 200, which specifies failure mode, criticality, stress, worst case and sneak circuit analyses. New equipment will be tested and evaluated at the new land based engineering site (LBES) at the Naval Ship systemsengineering Station (NAVSSES), Philadelphia, Pennsylvania. This site has been designed to test elevator systems and components and simulate shipboard conditions including temperature and humidity. Initially, equipment intended for the new AOE-6 and AE-36 classes will be tested. The site will also be able to test cargo and weapons elevator doors and hatches in an aircraft carrier configuration. The site includes a standard hydraulic power unit (HPU) to operate flush deck and in-trunk hatches and different door types. This paper describes the philosophy and methods for the overall standard elevator RDT&E effort and how it will improve the rel

This paper discusses the need and processes for designing warships to meet cost constraints and for managing warship acquisition programs during the design phase to assure effective adherence to production cost constraints by the design team. The resource control methodology used during the contract design of the Arleigh Burke class destroyer, DDG-51, is examined as a potential model for controlling the cost while maintaining the combat effectiveness of warships. The paper begins with a summary of the basic issue — the relationship among unit cost, unit capability, force level numbers, and force capability — showing recent trends in destroyer costs and force levels. This introduction also includes a discussion of the cost constraint for the DDG-51 in relation to historical trends and ship construction funding allocation. The resource control methodology used to reduce and control costs of the DDG-51 is discussed with a summary of the approach, key concepts and tools, chronology of key events, examples, and results achieved. A number of observations on this methodology are then made which are followed by comments on life cycle costs. The paper concludes with remarks on the future application of the resource control methodology and areas for further work to improve future resource control efforts.

Phased maintenance has expanded from a one class, three ship experiment to a viable maintenance strategy for the auxiliary and amphibious forces of the U.S. Navy. An evaluation of the program on the AFS class on the East Coast concludes that phased maintenance has solved the Atlantic Fleet AFS deployment problem, all PMAs have completed on time or early, IMA time and emergent voyage repair time are dramatically shorter, operational readiness has been enhanced, repair costs are declining moderately, the repair work definition process has evolved into a well-managed, streamlined and efficient process, and the port engineer concept continues to be as critical to the success of Atlantic Fleet phased maintenance as any single program element. Critics of expansion of the program charge that too much authority is being placed in the hands of a single individual, modernization will be inadequate, contractors will gouge the Navy with cost reimbursement contracts, a separate supply system will evolve, the Navy will saturate the industrial capacity of certain ports, and competition for Navy repair work will be eliminated with multiyear cost reimbursement contracts.

There is a great deal of emphasis currently in the Navy on the issues of reliability and maintainability. If a system or component is out of commission, it obviously cannot perform its mission. Thus, systems and components must be reliable, with low failure rates, and maintainable, with short repair times when the system does become inoperable. To be effective, these attributes must be incorporated into new ship systems early in the design stage. The Rankine cycle energy recovery (RACER) system is a heat recovery steam cycle designed to recover energy from the exhaust of an LM2500 gas turbine for augmentation of a ship's propulsion system. The RACER system provides several advantages to a gas turbine powered ship, one of which is improved fuel efficiency for significant annual fuel savings. This saving does not come free, however, since, in general, any additional system installed in the ship will have some maintenance requirements. In keeping with the Navy's current emphasis, a key philosophy in the design of the RACER system has been to minimize this maintenance burden. After a brief description of the RACER system and its design philosophy, the techniques being used during the design phase to minimize the maintenance burden on the fleet are presented. Trade-off studies concerning acquisition versus life-cycle costs, including fuel and maintenance costs, are discussed. Innovations incorporated into this state-of-the-art system are reviewed with an emphasis on design for affordability.
