WP 1.05: Operation and maintenance skills for Geothermal Power Plants

In this work package, we developed three training for three target groups namely engineers, inspectors and operators.

Training for Inspectors

For this target group we developed a 2-days workshop during lectures, exercises, assignments and background material. The target groups of the course are practitioners, lecturers and government. The entry level of the participants should be graduated from under graduated level or have experiences in geothermal related works.

Inspection of geothermal power plants requires insight in the engineering and construction of the power plant and its main components. Several inspection techniques are applied, depending on the component type, materials used, and operational parameters and operational environment of these components and structures. Most of the problems found in the surface facilities is caused by the lack of understanding on the behavior of the field, operation and maintenance activities of the power plant. Therefore, the understanding on the above subjects is very important. Based on the above conditions, the main of the course consists of basic knowledge, geothermal equipment plant, and inspection techniques applied for geothermal power plants.

Objective of the course is to understand the implementation of the overview of a geothermal power plant design (basic components and materials used in a geothermal power plant), to understand the equipment used for inspections in geothermal power plants, to understand the concept and principles of identifying high risk components and to understand the concept of proactive maintenance.

Our trainers here are: 

  • Kees van de ende (DNVGL)
  • Theo van der Meer (University of Twente)
  • Jooned Hendrasakti (ITB)
  • Frank Rasing (DNVGL)

Development and use

This course was developed by UGM team that has the following members:

  1. Samsul Kamal (samsul@ugm.ac.id)
  2. Khasani (khasani@ugm.ac.id)
  3. Fauzun (fauzun71@ugm.ac.id)
  4. Hari Agung Yuniarto (h.a.yuniarto@ugm.ac.id)

With contribution of :

  1. Kees van den Ende (kees.vandenende@dnvgl.com)
  2. Theo van der Meer (UT)

The potential, final users of these course materials are those who already graduated from undergraduate level with the background study of engineering and science, for both fresh graduates and ones who already involved in the geothermal related works.

Abstract

One of the problems during the exploitation stage of geothermal development is how to maintain the output of the resource. It is a natural situation when there is an output decline during the development due to the fluid extraction. However, a significant decline of the output can be observed for many fields around the world. The possible causes of the decline can be from subsurface condition and/or upper-surface facilities. Most of the problems found in the upper-surface facilities is caused by the lack of understanding on the behavior of the field, operation and maintenance activities of the power plant. Therefore, the understanding on the above subjects is very important. Based on the above conditions, the main of the course consists of basic knowledge, geothermal equipment plant, Reliability Centered Maintenance (RCM) in geothermal power plant.
