1 GENERAL 1.1 Project Overview

GLNG Operations Pty Ltd is planning the development of a liquefied natural gas (LNG) processing facility on Curtis Island near Gladstone. A gas transmission pipeline (GTP) called the GLNG Pipeline of approximately 420km length will transport coal seam gas (CSG) to the LNG plant from existing and future fields in the Roma, Fairview and Arcadia Valley area (see Figure 1). A Fibre Optic Cable (FOC) will be laid in the same trench as the GTP. The FOC will be connected to a dedicated Pipeline SCADA monitoring system. The Scope of Work (SoW) includes all buried and surface facility requirements for the mainline pipeline including a HDD/micro-tunnelled pipeline crossing from the mainland to Curtis Island (beneath the marine crossing near the “Narrows”). Approximately 85 kilometres of the onshore pipeline are constrained within the Callide Infrastructure Corridor (CIC) State Development Area (SDA) which is subject to coordination and access limitations imposed by the shared use of this corridor with existing and new pipelines being built by other LNG proponents. The Company is planning a large scale development to extract CSG from existing and future fields in the Roma, Fairview and Arcadia Valley area (Upstream) and to supply that gas for commercial sale and/or conversion to LNG.
