This paper described an application of the Analytic Hierarchy Process (AHP) to select the best maintenance strategy selection for mobile mooring system. Mooring accidents can cause serious injury or damage to the vessel, and hence it is necessary to determine the best maintenance strategy using AHP. Five maintenance strategies are considered namely corrective maintenance, preventive maintenance, run to failure maintenance, condition based maintenance and predictive maintenance. Floating structures use mooring system for station keeping in any water depths. Mooring system is a vital component for the safety of floating structures. Keywords: accident, maintenance, mooring, offshore
1. Introduction
Offshore operation needs a maintenance strategy to ensure the safety and efficiency of an installation. Inadequate maintenance has been a major issue in many accidents and incidents therefore it is important to organize the maintenance strategy (HSE, 2004). Mooring systems are the main components in floating platforms which are useful for positioning and station keeping. Mooring system failure can cause disastrous damage to the platform. It can be adrift or even collapse that may lead to the loss of life. Mooring system failures are due to anchor failure, mooring line breakage, appurtenance connection failure ((Silvianita et al. (2012) and (Silvianita et. al. (2011)). Hence it is important to select the best maintenance strategy to maintain the risk in daily activity. The objectives of this paper are to select the best maintenance strategy for mooring system and to analyze the sensitivity analysis. The maintenance philosophy has been changed into various maintenance types such as corrective maintenance, predetermined maintenance and predictive maintenance. Figure 1 illustrates the relationship between failure rate versus change in maintenance philosophy is showing decline trend. This figure also describes the strengths and weaknesses of the different maintenance types. There are many variations among practitioners regarding the terminology used to describe the maintenance strategy, in general the maintenance strategies are briefly the following:
Figure 1. Change in Maintenance Philosophy (Sethiya, 2006) (i) Run to failure maintenance (RFM) Run to failure maintenance strategy is a reactive management method that does not spend any money on maintenance until the equipment or machine failure. (ii) Preventive maintenance (PM) Preventive maintenance strategy are time driven that assume the equipment or machined will D- 101
degrade within a certain time based on their particular specification. Preventive maintenance programs uses bathtub curve to conduct equipment repairs which shown in Figure 2. The bathtub curve described new equipment has a high frequency of failure because of installation issues during the early time operation. The next period of time has relatively low frequency of failure for an extended period or called the normal period. The last period shows the increasing frequency of failure of the equipment.
Figure 2. Bath up Curve (Mobley, 2002) (iii) Predictive maintenance (PeM) Predictive maintenance strategy is a condition driven preventive maintenance that monitored the vibration of rotating machinery in order to identify initial problems and to prevent catastrophic failure. Preventive maintenance performs the repair schedules based on the intuition and the personal experience of the maintenance manager. In order to detect the signs of failure, predictive maintenance divides into two types methods which are condition based predictive maintenance and statistical based predictive maintenance. (iv) Condition based maintenance (CBM) CBM is a maintenance programs that helpful to define incipient faults before they become serious problems which is based on actual condition obtained from in situ, non invasive test, operating and condition measurement (Sethiya, 2006). (v) Corrective Maintenance (CM) Corrective maintenance strategy is event driven based on performing repair / maintenance action after the equipment or the system failure has occurred. This maintenance strategy is not concerned with scheduling inspections or service routines on deteriorating on deteriorating components (Kaiser, 2007). Table 1 shows the characteristics of maintenance strategy.
CM Corrective maintenance action is conducted after the failure occurs in order to eliminate the source of this failure or reduce the frequency of its occurrence
Table 1. Characteristics of Maintenance Strategy ((KSU), 2010) The Main Differences of Maintenance Strategy PM RFM CBM PeM Preventive Run to failure Condition Predictive maintenance maintenance based maintenance performs a list of action are maintenance analyze the acquired actions before the unplanned and uses a list of controlling occurrence of a on schedule, the measurements parameters in order failure in order to occurrence of a and data to find a possible prevent any failure in a acquisition temporal trend, it is degradation or to component can systems in useful to predict reduce the cause failures in order to when the controlled frequency of other monitor the quantity values failure. components in equipment excess the threshold the same performance in values equipment real time.
2. AHP Application for Maintenance Purpose
Maintenance strategies are developed by using AHP which enables to evaluate multi criteria D- 102
involved in order to select the best maintenance strategy. AHP is a structured approach that deals with multi criteria decision making. The AHP helps the decision makers determine the best alternative based on their needs and requirements. In order to make the judgment between two factors, AHP uses the fundamental scale to make the comparison easier. Table 2 shows the fundamental scale of absolute number developed by Saaty (1988). Table 2. The Fundamental Scale of Absolute Numbers (Saaty, 1988) Intensity of Importance 1 2 3 4 5 6 7 8 9 Reciprocals of above
1.1 – 1.9
Definition
Description
Equal importance Weak or slight Moderate importance Moderate plus Strong importance Strong plus Very strong or demonstrated importance Very, very strong Extreme importance
Two activities contribute equally to the objective
If activity i has one of the above non zero numbers assigned to it when compared with activity j, then j has the reciprocal value when compared with i. If the activities are very close
Experience and judgment slightly favor one activity over another Experience and judgment strongly favor one activity over another An activity is favor very strongly over another, its dominance demonstrated in practice The evidence favoring one activity over another is of the highest possible order of affirmation A reasonable assumption
May be difficult to assign the best value but when compared with other contrasting activities the size of the small numbers would not be too noticeable, yet they can still indicate the relative importance of the activities.
Maintenance strategies involve many choices, hence the AHP will help to choose the best maintenance policy to be selected. AHP approach has proved to be a valid support for selecting maintenance strategy (Zhaoyang, 2011). AHP has been applied for maintenance purpose in many areas such as in the chemical industry, electrical industry, onshore and offshore pipeline, etc as can be seen in Table 3.

3.The AHP Result and Application
The AHP start with the hierarchy level consists of four levels. The AHP hierarchy structure developed in this study is four level tree in which the top level represents the main objective of maintenance strategy selection and the lowest level comprises the alternative maintenance strategy. The evaluation criteria that influence the main objective in the first level are described at the second level and are related to five different factors namely people, environment, assets, D- 103
reputation and cost. Figure 3 describes the hierarchical structure for maintenance strategy for mooring system. The third level is the sub factor that can contribute to each factor of the mooring system failures. The four factors and their sub factor mooring system failure are consisting of: a. People considering the safety and health of the personnel. b. Environment, by taking into account the external damage and internal damage of the platform. c. Assets, by considering the direct damage having tangible effects of the failure and indirect damage into account the possible reduction of the failure on the working life of the platform. d. Reputation, by considering the performance and quality service. e. Costs, that can include the crew cost and spare past cost.

Figure 3. Maintenance Strategy for Mooring System Table 4 shows AHP output for maintenance strategy. The hierarchical structure for maintenance strategy as shown in Figure 2 is used to develop expert judgments based on AHP scale. There are 9 experts involved in this study. The results of the pair wise comparison of the first level of the hierarchy indicate that the highest factor of maintenance strategy is due to people namely 46% consisting of Safety namely 26.9%, and Health namely 19.2%. The second highest is due to assets of 14.3% due to the contribution of sub factors directly 12.6% and indirectly 3.7%.. The third highest is due to environment of 13.9% consisting of external impact of 4.1% and internal impact of 8.7%, and lastly is due to cost 13.7% that will affect the performance of 4.5% and quality service of 4.6%.

Sensitivity Analysis
Sensitivity analysis is used to eliminate the alternatives, to enhance a group decision process or in providing information as to the robustness of a decision (Erhan, 1991). The sensitivity analysis derives from Expert Choice software which is useful to determine sensitivity of the priority. There are five graphical sensitivity analyses, namely performance graphs, dynamic graphs, gradient graphs, two dimensional graphs and difference graphs. Concentrating to the highest priority of the criteria in the second hierarchy, three scenarios of interpretation are applied to define possible combinations of weights priority of the alternatives. Scenarios of interpretation consist of decreasing and increasing the initial weight priority of the highest criteria in the second hierarchy. Based on the calculation in the previous section, the highest criterion for maintenance strategy is people, hence the interpretations of the people priority is applied. The interpretations apply three scenarios in an attempt to identify the significant changes of the maintenance strategies. The interpretation scenarios consist of the decrease and increase of the priority value of the highest criteria of people as shown in Table 5.

Figure 4. Sensitvity Graphs Figure 4 shows the initial weight of priority of People, namely 46%. The weight of alternatives shows 31.3% for PeM, 23.5% for PM, 17.9% for CBM, 14.7% for CM and 12.6% for RTF. Hence the highest alternative is PeM with 31.3%.

Figure 5 shows the graphs of interpretation scenarios of maintenance strategies. Based on the interpretations obtained from the sensitivity analysis, the best maintenance is still PeM (predictive maintenance) even though it has been applied to several interpretations. There are a few changes when the people priority decreases 45.4%, PeM (predictive maintenance) priority 27.4% is reached and overcome by PM (preventive maintenance) with priority of 28%.

Table 6 defines the rank of maintenance strategy selection with three interpretation scenarios in order to see the changes of the maintenance selection. The result shows PeM is the best maintenance strategy in both interpretation scenarios decreasing 10% and increasing 11%, however for third interpretation decreasing 45.4% the best maintenance strategy is changed to PM (preventive maintenance). CBM remains in third ranking for maintenance strategy for all the interpretation scenarios. Generally based on the sensitivity analysis the priority of maintenance strategy selection is constantly stable, there are no significant changes of the priority unless the criteria and sub criteria of the hierarchy have been changed drastically.

4. Conclusion
Selecting the best alternative or choice is based on the highest priority of AHP result. A few key points from this paper can be highlighted as follow: The AHP result shows the best maintenance strategy on the basis of the likelihood of failure is PeM (Predictive Maintenance) with the priority vector of 31.3%. The sensitivity analysis shows that PeM (Predictive Maintenance) is still the best maintenance strategy. References
