This hefty unit removes carbon dioxide from the incoming feed gas before it is supercooled into a liquid state.
The amine absorber started its journey via a ship from South Korea and made the road journey in Papua New Guinea on a 192-wheeled, slow-moving modular transporter.
"It took a great deal of dedication from sea, road and plant crews to ensure the safe and successful arrival and installation of this enormous piece of equipment," Exxon said.
"During transport from the port at Motukea Island to the plant site, although the heavy load was travelling at a mere 5km per hour, average wait times for road users were reduced to approximately 20 minutes thanks to reopened sections of the old road."
To put the travel time in context, some studies indicate the average walking speed for non-elderly people is up to 5.43km per hour.
