Abstract.
Sorik Marapi Geothermal Power (SMGP) is one of the largest developing geothermal projects in Indonesia. This project is located in Mandailing Natal Regency, North Sumatera Province. KS ORKA acquired the majority shares of the company in mid-2016 and since then the project has completed drilling program for 18 wells and confirmed at least 55 MW of proven resources. The project aims to connect 240 MW power to The PT PLN grid. The Steam field Diagram Options (SAGS) conceptual design based on the wellpad separation concept with the separated fluids running the Well Head Units (WHU) installed within the production well pad. This SAGS concept is a decentralized system with shorter pipelines per plant. The SAGS concept has the advantage of a faster time to see its development compared to the traditional concept. High risk of that could occurs during geothermal exploration and development activities identifying risks of geohazard in early phase of geothermal development plan might cause some problems and catastrophic events such as damages on infrastructure, well pad, road access, pipeline, well leaks or broken, impairment of power plant facilities, and following cessation of electricity production. Moreover, these events also could affect the nature or environment surrounding the field and results fatality or loss of human lives. Therefore, it is very critical to have a well – structured and comprehensive method as a guide to identify and mitigate the geohazard risks. The aim of this study is to gathers and reviews disaster preparedness level in SMGP Project area especially geohazard such as earthquake and landslide. Evaluation of existing building using FEMA P-154 and ASCE 41-17 Tier 1 and 2 also explained on this study.
