• QMW built 247 structures in less than four months under its second contract for the Yamal LNG project
• First-time construction of bolt-connected stick built structures demonstrates precision capabilities
Qingdao McDermott Wuchuan (QMW) recently delivered the last batch of 247 structures for the Yamal liquefied natural gas (LNG) project, an LNG plant being built northeast of the Yamal Peninsula in Russia.
With a total weight of approximately 2,400 tons, the 247 bolt-connected stick-built structures were completed ahead of schedule in less than four months under its final work package. The scope of work included engineering, procurement, fabrication and packing. The structures are small pipe racks, platforms, sleepers and supports installed between process modules to support hook-up pipes, cable trays, etc.
Construction of the structures began in September 2016 at the QMW fabrication facility in Qingdao, China, and marked the first-time bolted-connected structures were built instead of the usual welded connection structures. The structures were fabricated in QMW’s mega-module assembly shop, which features four giant bays that allows all fabrication and assembly to be done inside which increases safety, quality and productivity.
“We greatly appreciated QMW’s excellent performance on this project in terms of safety, quality and on-time delivery,” said Ken Kasai, Site Manager of Yamgaz, a joint-venture composed of TechnipFMC, JGC and Chiyoda, who are designing and constructing the LNG plant.
“QMW has now completed two major work packages for Yamgaz, including the recently completed stick-built structures as well as fractionation process modules fabricated and delivered in 2016, ahead of schedule without a single Lost Time Incident and through an innovative sub-modules construction methodology,” said Leong Eng Chow, General Manager, QMW. “Our team continues to gain recognition for outstanding quality, health, safety and environmental performance on this project further demonstrating QMW’s international competitiveness, reputation and quality performance in the module fabrication market.”
Located at Sabetta, the Yamal LNG plant is the first LNG development venture in the Arctic with a planned total capacity of 16.5 million tons of LNG per year, and is one of the largest LNG projects in the world.
