Tesmec powers Master Gas Phase 3 project

As part of the ongoing Master Gas Phase 3 project in Saudi Arabia, Tesmec is carrying out large-scale trenching operations to support the expansion of the national gas pipeline network. The project involves excavating trenches 2.13 metres wide and 2 metres deep across two key sections of the pipeline route, which spans approximately 150 kilometres.

The geological conditions along the route vary significantly, including formations such as limestone, siltstone, granite, and basalt. To address these challenges, different trenching methodologies are being applied. In one section, a pilot trenching approach is used, where two machines sequentially excavate the trench, the first performing a narrower cut and the second completing the full width and depth in a single pass. In the other section, a double-cut method is applied, involving two machines widening the trench in stages to meet the final specifications. Excavated material is processed on-site for potential reuse as padding and bedding, reducing the need for imported materials. The work is supported by local operation and maintenance teams, ensuring equipment reliability and continuity across the project.
