Houston-based McDermott said it has completed an LNG construction study identifying tangible reduction pathways toward net-zero construction emissions on behalf of LNG giant Shell.
The results of this study provide a strategic framework for reducing greenhouse gas (GHG) emissions in LNG facilities during the project execution phase, according to a statement by McDermott.
Also, study results include emission reduction opportunities, in order of magnitude, based on mapping key sources and the identification of low-carbon alternatives during construction.
These include site efficiency improvements, replacing diesel-powered equipment with lower GHG intensity alternatives, module fabrication and construction and sourcing lower intensity raw materials, McDermott said.
The study also provides more clarity on the associated environmental, social and economic considerations of future projects, the firm said.
Building on this study, McDermott is also engaging with Shell to identify low-carbon solutions to help reduce GHG emissions in McDermott’s operations, it said.
“Operators continue to seek actionable plans to advance their commitments to net-zero emissions by 2050,” said Samik Mukherjee, McDermott’s executive VP and COO.
“Leveraging our unique LNG and modularization expertise, McDermott has developed multiple, innovative pathways to reduce and/or eliminate emissions throughout the life cycle of an LNG facility,” he said.
Mukherjee added that McDermott believes, in future scenarios, a combination of construction execution efficiency, modularization and targeted investment in construction emissions reduction initiatives could eliminate up to 65 percent of emissions associated with construction.
