1.2 Problem Description
The four MDM are proposed to determine the reliability of ship oil system with RGEC
method, they are: a.
Pertamina [7] has stated, if there is a non conformities
maintenance scheduling
that influences the reliability impact by hazard and
without reviewing significant or not failures, so the reliability is equal with value before hazard.
b. Pertamina [7] used harmonisation terminology
or maintenance
scheduling combination.
Bieman [1] has stated that if failure repaired onto many system which have almost the same
maintenance schedul with other system, that can join their repairing.
c. Rasmussen [8] had stated with Effective
Maintenance Strategies model. He stated that
the component replacement with high effectivity one could implied a cost saving. This strategies
call Effective Maintenance Program. d.
Innovation is divided into therminology and procedure. This therminology is enclosed at
Technology Atlas Project Form of Tokyo Programme on Technology for Development,
Kibrio [5]. Innovation is consist of human ware, techno ware, organ ware, and info ware.
System Reliability
is evaluated
with compliance of the five actions, they are:
1. Harmonisation to the duration of the component
maintenance and the subsystem are different. Harmonisation is implemented to the some of
them and then system reliability is calculated based on configuration.
2. If the 3-MDM happened, they are : hazard
handling, innovation, and using non standard effectivity component; it is necessary to
evaluate the system reliability after re- harmonisation.
3. Component and subsystem reliability is
determined with the judgement of how the effectiveness of the replacer component in
system and how long percentage of component and subsystem duration to duration of the
system.
4. Reliability reduction of the certain component
or subsystem is not valid when there is delay time or repairing so that causes system stops
running. 5.
If there is not significant component or subsystem and based on the design it is reliable
until the end of life time of the system, so its reliability is perfectly and never goes down.
This paper presents the result of a study case was using ship oil system RGEC based on TTF
data and MDM proposes was used to estimate the reliability of ship oil system and to understand the
phenomenon in speed down reliability reduction of maintenance system. Reliability determination is
the part of other reliability determination review based on non technical case. Temporary using,
paralel circuit as stand by, impulsive system, real caused by routine maintenance, are examples of
non technic reliability problem. Focussing on evaluation with compliance on five actions of
MDM are observed.
