GLNG Narrows Crossing Design
GLNG Operations engaged Atteris to undertake FEED of the Gas Transmission Pipeline (GTP) for The Narrows Marine Crossing. The selected Narrows Marine Crossing concept involved the construction of an approximately 4.4 km long, 3.4 m internal diameter segmental lined concrete tunnel to serve as a conduit for the 42 inch diameter pipeline and accompanying fibre optic cable (FOC).
Work Performed by Atteris
Atteris performed pipeline stress analysis of the tie-in spools at the tunnel entry and exit locations as part of their scope of work. Detailed spool stress analysis was performed Autopipe software.
