CASE STUDY
WOODFIBRE LNG ROAD TO NET ZERO
We are providing modular fabrication for the Wood昀椀bre LNG project in British
Columbia, which will be the world’s 昀椀rst net-zero LNG facility. The facility will operate
with ~86% lower carbon intensity than typical LNG facilities. Powered by electrically
driven compressors using renewable hydroelectricity, the LNG export plant will also
reduce stationary combustion emissions 14 times lower than a conventional facility.
McDermott’s project scope includes fabrication of 18 modules totaling more than
~35,000 metric tons and two electrical packages, all prefabricated in our QMW yard.
Our Marine Fleet
Our marine vessels are our largest source of operational
emissions amounting to ~74% in 2025. Decarbonizing
marine construction operations remains our greatest
challenge. While we monitor the maturity and availability
of low-carbon technology and infrastructure to support
remote marine operations, we remain focused on
improving energy ef昀椀ciency in our vessels where small
changes can deliver measurable impact.
In 2025, we initiated a feasibility assessment for shore
power technology across the 昀氀eet, considering vessel
routes, port infrastructure, grid renewable energy
composition, and cost-bene昀椀t factors.
ISO 50001 introduced a systematic approach to monitor,
review, and optimize vessel energy use. Monthly reviews
maintained attention on idle-period fuel consumption,
historically a key inef昀椀ciency driver. DB32 idle days
increased by ~50% year-on-year; despite this, fuel
consumption was ~21% lower than the annual forecast,
driven by improved engine load management and
reduced low-load generator operation. DB50 operational
days doubled, while fuel consumption rose only ~45%
supported by greater energy awareness and timely
maintenance of main engines – demonstrating a
decoupling of activity from fuel consumption growth.
