Maintenance is given a high profile in safety rules yet it is given little consideration during the design and construction of ships. The composition of direct maintenance costs is outlined and is subdivided into personnel equipment and material loss of hire and direct costs for dry docking shipyard use etc. Maintenance activities are then considered in terms of routine medium and great maintenance in which the latter includes intervention to significant parts of the vessel for example the keel or the hull. The connection between maintenance and safety is addressed in the light of the ISM Code. Finally a design approach to maintenance is presented.

An overview is given of the approach taken by the Amoco Orient Petroleum Company (AOPC) in developing a maintenance system and programme for the Liuhua Field in the South China Sea. The maintenance development plan has five phases. First was the development of detailed policies for equipment identification commonality and data acquisition. Next was the development of a detailed maintenance strategy and definition of the role of MAXIMO a commercially available maintenance management program. This was followed by the development of an equipment and spare parts database. Fourth on the list was the development of the preventative maintenance programme. The final stage was training and implementation.

Like many government departments the MoD (Ministry of Defence) is under ever-increasing pressure to reduce costs whilst maintaining or improving its outputs. A number of initiatives have been put in place to improve operational availability whilst also reducing costs. One key methodology introduced more than 10 years ago to reduce through-life maintenance costs was RCM (reliability-centred maintenance). However this change to maintenance regime was not without difficulty and consequently a number of problems arose. The MMSG (maritime maintenance support group) was formed in early 2008 to group together a number of different teams involved in the maintenance administration and delivery process whose work had until that point been done in isolation and in an incoherent way. This paper examines the problems that were identified the programme of work that has commenced to reduce maintenance costs sharpen its governance and administration and improve the operational availability of the platforms. All this has to be done whilst providing value for money and without compromising safety.

Maintenance of technologically advanced systems is costly due to the high costs of spare parts and the required labour hours. At the same time maintenance is of vital importance to keep the system availability at an acceptable level. This paper shows how understanding the physics of failure can be used to improve the efficiency of the maintenance process and to assist I keeping the future fleet affordable. In this paper it is shown how technical innovations especially those exploiting the physics of failure can lead to more efficient maintenance processes and keeping the fleet affordable. Three aspects are discussed. Firstly condition monitoring is mentioned as a technique that enables just-in-time maintenance. The recent development of innovative sensors provides the opportunity to set up new condition monitoring systems but knowledge of the failure mechanisms is required to select appropriate sensors and suitable analysis methods. Secondly understanding the failure mechanisms enables the application of usage- and load-based- maintenance which can be very effective as is shown by a case study.

This paper describes a quantitative model for risk-based integrity maintenance planning for offshore pipelines. The model calculates the risk level as the product of failure consequences and failure probabilities. The model quantifies the benefits associated with different maintenance alternatives by calculating their impact on the probability of failure and risk level. A formal decision analysis approach is then used to evaluate the costs and benefits associated with each alternative and identify the best overall maintenance strategy. This model differs from previous work in risk-based planning in that it uses structural pipe failure models and reliability analysis techniques to calculate failure probabilities quantifies the impact of maintenance on risk and uses a methodology based on decision theory to identify optimal choices. The paper includes the results of simulations dealing with maintenance optimization for corrosion and mechanical damage. The most significant aspect of this work is that it provides a novel approach to managing pipeline integrity in a cost-effective manner.

Session Reports on Welding and allied processes in maintenance and repair, showing the wide range and variety of the application of welding to maintenance and repair. The papers have been divided into five groups: study of techniques used in repair work, problems raised in repair work by the nature of the base and filler materials and by the properties to be obtained in service, typical examples of the repair of parts of the maintenance of equipment in particular industries, organisation of maintenance and repair work and economical questions relating to the use of welding and allied processes in maintenance and repair work. The fields covered by the papers are small repairs of a great number of various objects, important repair work of a great number of the same or similar objects, and special cases of repair of particularly large cast parts in rolling mills, presses and the like. The problems dealt with include weldability in all its aspects, fatigue, influence of residual stresses and quality control.

Maintenance encompasses all efforts done to restore a system or equipment's inherent reliability. The basic maintenance philosophy began with the concept of failure maintenance. This involved corrective or breakdown maintenance and preventative maintenance. With the advance of technology has come the concept of CBM (condition-based maintenance). This involves regular measurement of diagnostically significant parameters which provide the basis for equipment condition monitoring. The CBM principles advantages and procedure are outlined. Current CBM practice is described and the way ahead is given. The CBM tools (diagnostic and management) are discussed. Finally the RMC (reduced maintenance concept) is also discussed.

The method of planned maintenance developed by B.P. Tanker Co Ltd is described. Three basic steps are taken for each ship compiling an index of all equipment requiring maintenance preparing maintenance routines and setting about a maintenance programme covering a five year cycle for every item in the index. Manhours available for maintenance work were calculated aiming at a balanced workload over the five year cycle. Each ship was provided with a library of cards of maintenance routines and a visual display planning board. Miantenance report forms are then produced which act as input forms into a computer system. Both planned and unscheduled main tenance may be monitored by this method "Planned Maintenance Reviews" "equipment performance report" and "unit maintenance history" are all generated by the computer program. Future developments are discussed.

To assure safety to protect the environment and to secure the commercial success of the business risks must be effectively managed. By reducing the likelihood of equipment failure maintenance is a risk control measure but to be effective it must be managed by recognised risk management principles. Historical approaches to maintenance review and development are discussed. A risk based review of existing maintenance (REM) to establish how successful the existing maintenance actions are in reducing risks to acceptable levels the cost benefit provided by the existing or proposed maintenance actions and areas where risked costs indicate that further maintenance actions should be considered is outlined. An in-house analysis tool called CyberAlpha is used. Risk based REM techniques have been shown to be particularly effective in the offshore oil and gas sector and three case studies are presented.
