Pertamina Gas Subholding and KAI Conduct Dynamic Test of LNG Fueled Train

Jakarta, December 16, 2021 - PT PGN Tbk, as Pertamina's Subholding Gas, and PT KAI, conducted a Dynamic Test of LNG Technology train that will be used to serve the Jakarta - Surabaya route. Dynamic Tests is one of a series of Pilot Projects to reduce subsidized diesel.

The SOE's synergy in converting fuel oil to LNG fuel uses the Diesel Dual Fuel (DDF) system so that the trains powered by diesel will operate with a mixture of two fuels (gas and diesel). Gas is used as the main fuel, while diesel is used as a lighter that helps lubricate and cool the combustion chamber.

Director of Strategy and Business Development of PGN, Heru Setiawan, explained that before the Dynamic Test, a Static Test had been carried out on the generator train when the engine was idle. The Static Test shows that when compared to diesel fuel, the engine performance is more efficient.

"The success of the static test will be supported by the dynamic test, where the engine operation is tested under actual conditions. The goal is to confirm the results of the static test and test the durability of the DDF system in operational conditions," said Heru (16/12/2021).

Fuel cost efficiency, lower gas engine maintenance costs, SOE synergy, freight transportation utilization, and the possible use of PT KAI's station land for environmentally friendly energy are all advantages of LNG fuel on trains (green energy).

"The use of LNG fuel is expected to realize cost efficiency and support operations as well as provide benefits for the transportation user community. Hopefully, it can be sustainable and enter the implementation stage. As a result, it can benefit both parties and the community," Heru explained.

This Dynamic Test was attended by the Director of Engineering and Environment of Oil and Gas, Wakhid Hasyim, Director of Facilities Management of PT KAI, Eko Purwanto, VP Gas, Power & NRE Business Development & Portfolio of PT Pertamina (Persero), Bambang Suprihanto, and representatives of BPH Migas Management at Pasar Senen Station.

PGN and KAI continue to coordinate for LNG needs and the most efficient logistics scheme in the southern region of Java. Klaten Regency, Karang Anyar Regency, and D.I Yogyakarta are among the city planned to be supplied, which are divided into two stages.

Currently, PGN has identified four delivery points of LNG to the southern part of Java Island. The LNG Isotank that will be used is 20 ft in size and was sourced from Surabaya (Teluk Lamong).

"We are optimistic that LNG  fuel can provide benefits for KAI and PGN Group, especially supporting the government in reducing fuel imports," said Heru.**
