Slope Evaluation & Geomechanical Assessment at Musandam Power Plant

Technical Assessment and Upgrade Recommendations for Critical Plant Slopes

The Musandam Power Plant required a comprehensive evaluation of an existing slope system surrounding key operational areas.

TEICO, through Marmol Integrated, carried out a detailed geomechanical assessment, slope condition analysis, and engineering recommendations to upgrade, reinforce, and future-proof the site's protection measures.

The study ensures that the plant maintains long-term operational safety and compliance with evolving geotechnical standards.

Project Overview

The steep rock slopes adjacent to facility structures and access zones were showing signs of localized instability, weathering, and inconsistencies in older protection works.

To address these concerns, the client requested a full evaluation to determine the current stability state, identify potential failure modes, and outline a reliable, cost-effective protection strategy.

Project Details

Project: Evaluation of Slope in Musandam Power Plant (2023)
Client: Musandam Power Plant
Main Contractor: Marmol Integrated LLC
Subject:
- Geomechanical assessment of existing slope protection
- Evaluation of current slope condition
- Design and recommendations for additional slope protection requirements

Challenges Identified

Aging Slope Protection MeasuresExisting systems showed degraded elements and inconsistent performance across different sections.
Weathered Rock Mass and Local InstabilitySurface erosion, block loosening, and jointing patterns increased the risk of small-scale failures.
Critical Infrastructure ProximitySlopes are located near essential plant components, requiring accurate diagnosis and reliable engineering solutions.
Lack of Updated Stability DataPrevious assessments were outdated, requiring fresh geomechanical analysis to establish current conditions.

Solution Implemented:

1. Comprehensive Geomechanical Assessment

•Conducted detailed mapping of fractures, joint orientations, and potential failure planes.
•Evaluated rock strength, surface conditions, and weathering profiles across all sections.

2. Review of Existing Protection System

•Inspected installed mesh, anchors, and surface treatments to determine performance gaps.
•Identified areas requiring reinforcement, replacement, or redesign.

3. Stability Analysis & Risk Classification

•Performed slope stability evaluations using updated site geometry and rock mass parameters.
•Classified hazard levels and pinpointed zones requiring immediate attention.

4. Design of Additional Protection Measures

•Proposed engineered solutions such as mesh upgrades, additional rock bolts, local reprofiling, or drainage improvements.
•Developed a prioritized intervention plan suitable for staged implementation.

Project Outcomes: Comprehensive Slope Evaluation & Geomechanical Assessment at Musandam Power Plant

Enhanced Understanding of Slope Behavior

The assessment provided a clear and updated picture of the slope's structural condition, identifying key instability drivers and areas needing reinforcement.

Targeted Protection Strategy for the Client

The delivered recommendations allow the power plant to address only the necessary zones—optimizing cost, material use, and construction time while improving safety.

Improved Risk Management for Critical Infrastructure

By mapping failure-prone areas and verifying existing protection reliability, the plant now has a structured plan to mitigate geotechnical hazards that could affect operations.

Future-Ready Slope Protection Design

The proposed solutions incorporate modern geotechnical standards and long-life materials, supporting long-term slope performance in Musandam's harsh coastal environment.
