Brine Injection Pump Operation and Maintenance Actions (A Lesson Learned of Dieng Geothermal Field)

Abstract

A geothermal industry is a high-cost and high-risk industry that common problems arise from the fluid characteristic. In order to achieve an effective and efficient operation, a series of activities such as maintenance should be well-managed. Dieng geothermal field is owned and operated by PT Geo Dipa Energi which had a great lesson learned about a brine injection. This paper was carried out to identify the problems and the maintenance actions related to the brine injection pump. The two main types of brine injection pump that being used are vertical and horizontal pump. The identifying process was started by collecting historical data of problems and maintenance. The comparison result between two types of pump is being used to determine which one of the pump that has the highest maintenance effectivity and reliability according to the Dieng’s characteristic. Furthermore, this paper can become a reference for another geothermal field in order to determine the type of pumping unit and prepare the maintenance actions.
