Abstract:
This paper develops a simulation-based model to derive critical maintenance
parameters towards optimizing a deep drilling rig availability and mainten-
ance costs. Full factorial analysis is performed to derive the effects and inte-
ractions of the derived parameters, based on which ones with a significant ef-
fect on the availability and maintenance cost are selected. The case study
based model incorporates maintenance, spares and workforce strategies for a
geothermal drilling rig. The results offer essential maintenance decision sup-
port to both the management and maintenance team of the company and
have the potential of further offering insights that eventually reduce the cost
of drilling.
