JAKARTA (Rambu Energy) – Houston-based McDermott International, Inc. (NYSE:MDR) said that it has delivered the riser support structure (RSS) for the INPEX-operated Ichthys LNG project’s subsea, umbilical, riser and flowline development, in offshore Australia.
McDermott designed the concept of the structure by combining its expertise of its in-house Singapore based engineering team and its fabrication facility located on Batam Island, Indonesia.
The 7,200-ton RSS connects the field’s subsea infrastructure to a semi-submersible central processing facility. The RSS structure is comprised of a tower, more than 328 feet tall, with an arch 410-foot long also designed and fabricated by McDermott to be installed at a later date, to support 25 large-diameter flexible risers and dynamic umbilicals.
“The RSS accounts for more than 25% of the total 28,700 ton of subsea structures we are fabricating for Ichthys,” explained Duncan. “It is an integral piece of the subsea field architecture as all other subsea structures will be installed and oriented relative to its location.”
“The completion of the RSS fabrication, load-out and successful installation is a major milestone,” said Tony Duncan, Executive Vice President Subsea of McDermott said in a media statement.
“The timely delivery of the RSS is testament to the effective project execution delivery model we have adopted for the Ichthys LNG Project highlighting the strong capabilities of McDermott’s team comprised of industry experts from key locations, including Singapore, Batam and Perth and significantly de-risks the project execution schedule,” he said.
The Ichthys LNG Project is a joint venture between INPEX group companies (the Operator), major partner Total and the Australian subsidiaries of Tokyo Gas, Osaka Gas, Toho Gas and Chubu Electric Power. Gas from the Ichthys Field, in the Browse Basin approximately 124 miles offshore Western Australia, will undergo preliminary processing offshore to remove water and raw liquids, including condensate.
The gas will then be exported to onshore processing facilities in Darwin via a 552 miles pipeline. The Ichthys LNG Project is expected to produce 9.3 million tons of LNG and 1.8 million tons of LPG per annum, along with approximately 100,000 barrels of condensate per day at peak. (*)
