Pluto Train 2 Project: LNG Expansion Development in Western Australia

Introduction

The Pluto Train 2 Project is a major liquefied natural gas (LNG) infrastructure development located in Western Australia’s Pilbara region. The project represents an expansion of existing LNG processing capability through the addition of a second LNG processing train at the Pluto LNG facility near Karratha.

The development is designed to process natural gas from the offshore Scarborough gas field and convert it into liquefied natural gas for international energy markets.

Large-scale LNG projects such as Pluto Train 2 require the integration of multiple engineering disciplines, including gas processing, mechanical systems, electrical infrastructure, automation, process control, safety systems, and industrial instrumentation.

This article provides an overview of the Pluto Train 2 Project based only on publicly available project information, while separating confirmed project details from general LNG industry practices.

What is the Pluto Train 2 Project?

An LNG “train” refers to an individual processing unit within an LNG facility that performs the treatment and liquefaction of natural gas.

The Pluto Train 2 Project involves the development of an additional LNG processing train at the existing Pluto LNG facility in Western Australia.

The project is part of a wider gas development programme involving:

  • Offshore natural gas production
  • Gas transportation infrastructure
  • LNG processing expansion
  • Domestic gas supply capability
  • Export infrastructure

The purpose of the project is to increase LNG processing capacity by connecting new gas resources with existing LNG infrastructure.

Pluto Train 2 Project Location

The Pluto Train 2 facility is located near:

Karratha, Western Australia

The facility is situated within the Pilbara region, an area recognised for large-scale resource and energy developments.

The location provides access to established industrial infrastructure, including:

  • Existing LNG facilities
  • Port infrastructure
  • Regional logistics networks
  • Industrial support services

Using an existing LNG site allows additional processing capacity to be developed through expansion of an established energy facility.

Connection with the Scarborough Gas Field

The Pluto Train 2 Project is associated with the offshore Scarborough gas field, located approximately 375 kilometres off the coast of Western Australia.

The development involves connecting offshore gas resources with onshore LNG processing infrastructure.

The overall gas supply chain includes:

  1. Offshore gas production
  2. Transportation of natural gas to the LNG facility
  3. Gas processing and treatment
  4. LNG production
  5. Storage and export

The connection between offshore gas production and onshore LNG processing demonstrates the complexity of modern LNG developments, where multiple systems must operate together safely and efficiently.

LNG Production Capacity

The Pluto Train 2 Project is designed to provide approximately:

5 million tonnes per annum (Mtpa) of LNG processing capacity

This additional capacity expands the LNG production capability of the existing Pluto LNG facility.

The project also includes domestic gas infrastructure designed to support supply to the Western Australian domestic gas market.

Major Components of the Pluto Train 2 Development

LNG Processing Train

The LNG processing train is the central processing unit responsible for converting natural gas into LNG.

The process generally includes:

Gas Treatment

Raw natural gas contains components that must be removed before liquefaction.

Typical gas treatment processes remove:

  • Water
  • Carbon dioxide
  • Other unwanted compounds

Gas treatment improves LNG quality and protects downstream equipment.

Liquefaction Process

After treatment, natural gas is cooled to extremely low temperatures until it changes from a gas into a liquid.

Liquefied natural gas occupies significantly less volume than natural gas in gaseous form, allowing efficient transportation by LNG carriers.

LNG Storage and Export

After production, LNG is stored in specialised storage tanks before being transferred to export vessels.

LNG export facilities require reliable operation of:

  • Storage systems
  • Loading systems
  • Supporting utilities
  • Safety systems

Construction and Development Progress

The Pluto Train 2 Project has progressed through several major construction phases.

Large LNG developments often use modular construction methods, where major plant sections are fabricated separately before being transported and assembled at the final project location.

Public project updates have reported the delivery of major LNG modules to the project site as part of the construction programme.

The project is targeting LNG production during 2026.

Engineering Considerations in Large LNG Projects
