The Queensland Curtis LNG (QCLNG) project off the coast of Gladstone, Queensland, Australia, is the first LNG project to liquefy coal seam gas and deliver an LNG cargo. Two more LNG projects, Gladstone LNG (GLNG) and Australia Pacific LNG (APLNG), also began their LNG production in 2015. In quick succession, each customer hired Bechtel to design and execute their project on a lump-sum basis. The three island projects are located side-by-side and are only accessible by water, presenting a unique set of challenges and opportunities. These simultaneous construction programs are part of the largest concentration of private-capital investment in Australia's history. This paper discusses Bechtel's extensive experience in modular design of the ConocoPhillips Optimized Cascade process technology and its innovative program for successfully delivering these projects by a direct-hire approach. Each project optimized the extent of modularization through construction-led engineering and employed a unique execution approach in collaboration with fabrication yards. Each plant design is based on highly efficient aero-derivative gas turbines with power augmentation for refrigeration compressor drivers. Highly efficient nitrogen rejection units minimize the environmental impact and safety hazards, while maximizing the performance, flexibility and ease of modularization. To effectively execute multiple projects on the island, a centralized service strategy has been adopted for standardization, knowledge sharing and alignment with customers, regulators and the community. The benefits to the Gladstone area economy, craft training and community development programs are also addressed.
