Rock Stabilization Study at the Musandam Gas Plant

A Comprehensive Geotechnical and Hydrology Assessment for a Critical Energy Facility

The Musandam Gas Plant is located in one of Oman's most rugged mountainous regions, where steep slopes, active drainage pathways, and complex geology can influence long-term stability. To safeguard plant operations and mitigate slope-related risks, a detailed geotechnical investigation and hydrological assessment were carried out.

TEICO, through its specialist geotechnical team, delivered a data-driven study that forms the technical foundation for future stabilization and protection works.

Project Overview

The study assessed the stability of slopes surrounding the Musandam Gas Plant, combining geological mapping, topographic surveying, hydrological analysis, and numerical modeling. The objective was to evaluate existing conditions, identify potential failure mechanisms, and develop targeted recommendations for slope stabilization and risk reduction.

Project Details

Project: Rock Stabilization Study at Musandam Gas Plant
Location: Musandam Governorate, Sultanate of Oman
Client: OQ
Scope:
- Mountain hydrology assessment
- Topographic survey
- Slope stability analysis
- Design recommendations for stabilization

Challenges Identified

Highly Variable Mountain TerrainSteep elevations and irregular topography introduced multiple potential failure modes.
Fractured and Weathered Rock MassesGeological mapping revealed discontinuities, joint sets, and weathering patterns affecting slope behavior.
Hydrology Impact on Slope StabilitySeasonal runoff and concentrated flow paths increased erosion potential and pore-pressure buildup during rainfall events.
Proximity to Critical InfrastructureSlope instability could affect operational safety, access roads, and plant facilities.

Solution Implemented:

1. Detailed Topographic Survey

•Collected high-resolution topographic data to build accurate slope models.
•Mapped drainage lines, slope angles, breaklines, and potential hazard zones.

2. Geological & Geomechanical Assessment

•Conducted on-site geological mapping to classify rock mass conditions and identify structural discontinuities.
•Evaluated rock strength parameters essential for shear and stability calculations.

3. Hydrological & Surface Runoff Analysis

•Assessed catchments, flow pathways, and rainfall-runoff behavior across the surrounding mountains.
•Identified erosion-prone areas and zones where water can accumulate or infiltrate into the slope.

4. Slope Stability Modeling

•Performed limit-equilibrium and kinematic analyses to evaluate failure mechanisms such as planar, wedge, and toppling failures.
•Assessed both dry and saturated conditions to understand rainfall impact on slope performance.

5. Stabilization Recommendations

•Proposed tailored slope protection solutions including mesh systems, rock dowels, surface drainage controls, and catchment ditches.
•Suggested monitoring strategies and phased stabilization works depending on risk priority.
