Inpex has finalised details of the planned repair work to its natural gas pipeline network in its native Japan that was damaged more than two years ago by Typhoon Hagibis.

The restoration work is scheduled to begin next year following the destruction caused by the typhoon in October 2019.

Currently, the Tokyo and Matsumoto pipelines have limited capacity compared to before the typhoon due to each being connected to different pipelines because of damage caused by the Chikuma River flooding.

Inpex said its pipeline infrastructure can be rendered safe in the event of future flooding by laying the repaired section at a greater depth below the river.

Pipelaying under the restoration work plan, which has been approved by the Minister of Economy, Trade and Industry, is intended to start in early 2022. Meanwhile, construction work on the connecting stations of both pipelines will commence in mid-2023 with the entire workscope scheduled for completion at the end of 2024.

Inpex’s natural gas trunk pipeline network extends approximately 1500 kilometres across the Kanto, Koshinetsu and Hokuriku regions.
