CBM (condition-based maintenance) was instituted by the US Navy in 1998 the goal being to move from time-directed preventive maintenance to condition-directed maintenance. The use of sensors algorithms and automated reasoning and decision-making models to monitor equipment operations provide critical analyses to operators that will help prevent impending failure. CBM technology should detect and classify impending failures; predict the remaining life cycle of equipment interface with the control system to take action; provide support in performing corrective maintenance; provide data to life cycle management activities and update logistics support systems. It is anticipated that this should result in significant improvements in safety reliability and affordability. AUTOLOG is offered as an application and process to gather more real time data needed for CBM from one source that can be quickly and easily provided to distant engineering support activities for gas turbines systems while also easing record keeping and data transmittal requirements for the fleet.

Naval propulsion requirements and the development of a standard gas turbine marine propulsion machinery package (based on marinised aircraft engines) for use in Royal Navy destroyers and frigates are discussed. Mention is made of design testing and trials with the Rolls Royce Olympus (TMIA) and Tyne (RMIA) gas turbines; the Olympus/Tyne main propulsion machinery package; the module concept of turbine enclosure and installation; maintenance evaluation and design modifications.

Development details of the modern Royal Navy of Oman (RNO) which evolved in the 1970's as a collection of armed dhows and other small craft. As the RNO must patrol large coastlines and the Straits of Hormuz a new purpose built naval base has been proposed to maintain the growing fleet. This paper examines the function of this new base; the upkeep philosophy maintenance defect repair of vessels; individual equipment overhaul; and personnel concerns.

US Navy ships generate used HM (hazardous material) during the operation and maintenance of machinery and equipment and the cleaning and preservation of ship spaces. In order to protect the environment and prevent the unnecessary release of harmful products to the world's oceans the Navy established a policy that requires most used HM to be retained on board (with a few exceptions) until it can be turned over to a shore activity for processing. The shore activity is responsible for determining whether the material may be reused as is processed and then reused or has no further use and must be disposed of as an HW (hazardous waste). Several problems result from the Navy's used HM policy. These issues are addressed and solutions are discussed. These solutions will enable the Navy to reduce the amount of used HM generated by its ships effectively removing the material from the ship to a supporting Navy shore activity streamline and standardise the ship-to-shore transfer process and train shipboard personnel involved in the offload of used HM.

The Functionally Identified Maintenance System developed by the Royal Navy and taught at HMS Collingwood is described in detail. Fault diagnosis is approached with specially prepared proceedings and documentation and similarity between FIMS and the use of algorithms is discussed.

The increasing use of simulators for naval and merchant marine crew training and experience is discussed. Examples of equipment in use for procedure training maintenance training total environment (heat noise etc) simulation simulation of specific plant (Boiler turbines engines etc) and experience of malfunction are described.

Annual corrosion control costs have led the Navy maintenance community to institutionalise state-of-the-art surface preparation coating and inspection procedures for seawater ballast potable water and other critical internal tank and void areas. These areas are very expensive to maintain in a corrosion-free condition and often succumb to varying degrees of structural damage. This new direction will double or triple the current service life of the tank corrosion control systems. Here the implementation of such state-of-the-art processes and materials to various surface ship tank-coating operations is commented upon.

The book covers the fundamentals of boiler development, design, construction and operation associated with post- World War II vessels of the United States Navy. The first two chapters provide a background to steam generation and ship propulsion. Chapter 3 is a fundamental study of naval boiler design and construction. The last four chapters deal with basic operating equipment and techniques (boiler types: furnace boilers, superheat, circulation boilers, nuclear power ship propulsion) and boiler water treatment, supplying heat to the boiler and principles of boiler operation and maintenance.

A managed programme to review engine failures and take necessary preventive measures has been in place successfully in the Royal Navy since the introduction of gas turbines into service in the 1970's. One of the more prominent failure mechanisms with the Tyne RM1C and Spey SM1A engines has been the degradation of main line bearings accounting for 25 percent of all engines rejected. Historically since the first recorded incident in March 1987 the failures pointed to poor performance of the bearings themselves. However maintenance studies and recent analysis indicates that a vast proportion have occured through previously unidentified chloride corrosion as a result of contamination of the lubricating oil system with salt water from the seawater lubricating oil cooler (SWLO cooler). Despite joint ownership of both engine variants with the Royal Netherlands Navy there was no clear evidence until about six years ago to suggest why the tube perforation was occuring. Indeed the fact that failures have only occured in Royal Navy service is an interesting twist to the problem.

An attempt is made to explain how ships under the Australian White Ensign are operated and maintained. In this case 6 ships are looked at the youngest of these being fifteen years old and the oldest being nearly thirty. After some introductory information a look is taken at the history - past present and future. Next each of the 6 ships - one off types of ships (orphans) under the control of the Amphibious and Afloat Support System Program Office or AASSPO - are listed with brief information. This is followed by consideration of some differences between merchant and naval practices. Lastly the challenge of the AASSPO to manage the process of maintenance and sustainment of this aging group of ships is looked at.

Pollution prevention is a key element in meeting the challenges of the Navy's Fleet in the new millennium. The P2 (pollution prevention) Afloat program was established in 1995 to develop pollution prevention strategies for the US Navy Fleet. Its goal is source reduction of HM (hazardous materials) used in standard shipboard maintenance and other afloat activities. Executive Order 12856 requires federal facilities to reduce the release of hazardous substances by 50 per cent by 1999 compared to a 1994 baseline. Studies show that up to 70 per cent of the hazardous waste processed at Navy facilities is obtained from HM offloads from ships. The P2 Afloat Team is achieving source reduction goals by identifying assessing and implementing source reduction opportunities aboard ships and focusing on the direct use or minimal re-engineering of COTS (commercial off-the-shelf) products. There have been many challenges and lessons learned during research procurement test and evaluation installation and return on investment analyses of P2 Afloat equipment. Applying these lessons learned regarding pollution prevention in the maritime environment is essential in order to meet the challenges of the Fleet in the new millennium.

Navies around the world are increasingly aware of the need to prove to the public and politicians that their submarines are safe - for their crews and the environment. The trouble is that only the world's biggest navies have the personnel and know-how to test the safety of their submarines in service or any new buildings and check the quality of maintenance work. The solution is to put the quality assurance process in the hands of a classification society. That is precisely what the South African Navy did with GL (Germanischer Lloyd). GL have been involved with submarines for many years and with the naval sector for some 30years. GL (Germanischer Lloyd) is now proud to announce that they have certified the world's first naval submarine with a Certificate of Class. The classification of a submarine involves an independent review of the design and the safety during the construction and in-service phase which releases the navy from the pressure to prove to the public that their submarines are safe for the crew and the environment. Here the benefits of classing a naval submarine are highlighted and the experience made with classing the first naval submarines is reported.

This paper will address the through life support program for the Victoria Class Submarines (VCS). Consideration will be provided for cost of ownership maintenance optimization working with industry performance metrics and Extended Docking Work Periods (EDWP). The backbone for future long term support of VCS will be Victoria In-Service Support Contract (VISSC). The VISSC infrastructure is aligned with five main pillars: Project Management Records Support Services Engineering Support Services Material and Logistics Support Services and Maintenance Support Services. The paper will discuss the ongoing sustainment of the Victoria Class platform focused on being able to meet its operational objectives and the dependence on a proactive technically competent team interacting with a host of marine system specialists within the Canadian Navy and abroad.
