• The Ichthys LNG Project is a joint venture between INPEX, major partner Total, CPC Corporation Taiwan, and the Australian subsidiaries of Tokyo Gas, Osaka Gas, Kansai Electric Power, JERA, and Toho Gas. At peak operation, the project is expected to produce up to 8.9 million metric tons of LNG and 1.6 million metric tons of LPG per year, along with approximately 100,000 bbl/d of condensate. The Ichthys Field is estimated to hold about 12 trillion cubic feet of gas and more than 500 million barrels of condensate. The Ichthys LNG Project’s floating production, storage, and offloading (FPSO) facility, Ichthys Venturer, safely sailed away this July, and upon reaching its destination will be moored about 3.5 kilometers from the central processing facility (CPF), Ichthys Explorer.

    The primary purpose of the FPSO is to separate multiphase liquid from the CPF into condensate and rich monoethylene glycol (MEG). In addition to condensate processing and storage, the FPSO includes a MEG Regeneration Unit (MRU), with MEG process technology and MEG key equipment within this package provided by NOV’s Wellstream Processing team, a group within the Process and Flow Technologies business unit. MEG is being used as a hydrate-inhibition agent for the infield gas to the CPF, and the MRU will remove hydrocarbons, water, and salts from the rich MEG (liquid phase after separation of gas and liquids) and provide a lean MEG (clean glycol) for reinjection at the field. The Wellstream Processing team is a leader in MEG regeneration and reclamation technology, and the Ichthys LNG Project’s MRU is the largest unit ever delivered, with a capacity of 303.5 m³/hr of rich MEG. The NOV scope of work for the MRU includes detailed process design of the complete MEG system as well as engineering, procurement, and delivery of 12 MEG key equipment pieces ranging from pumps, heat exchangers, and pressure vessels to vacuum skids, reclamation centrifuges, pre-treatment, and hydrocarbon centrifuges.

    In addition to the above deliveries from NOV’s Process and Flow Technologies business unit, NOV’s Fiber Glass Systems business unit also delivered Bondstrand™ glass-reinforced epoxy (GRE) piping, designed and engineered for 40 years of design life for both the hull and the topsides, to the Ichthys LNG Project for the following applications: ballast, seawater cooling, cooling medium, service water, bilges, and sewage. Materials for the hull were delivered in 2,440 spools ready for immediate installation at site. The total pipe quantity was 11 800 m, in sizes from 1 to 40 inches and with 16,884 fittings. Over 90,000 diameter inch joints were bonded and tested at the factory. Materials for the topsides were delivered in 5,580 spools. The total pipe quantity was over 15 180 m, in sizes from 2 to 40 inches and with 15,118 fittings. Over 184,000 diameter inch of joints were bonded and tested at the factory. Critical systems were analyzed for surge and stress and site supervision ensured work was done by certified bonders according to working procedures.

    NOV is proud to be a part of this landmark development, which is one of the largest and most significant oil and gas projects in the world.
