GLNG Narrows Crossing Design

Background

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.

Benefits

Atteris performed FEED of the GLNG Narrows Crossing, including  detailed analysis of the tie-in spools at the tunnel entry and exit locations.
