Advanced Solutions for Onshore & Subsea Pipelines
At ASHAAH LIMITED, we provide specialized pipeline engineering consultancy to support energy transport across terrestrial and marine environments. From initial feasibility routing to asset life extension, our designs ensure absolute safety, stability, and code compliance.
Our pipeline specialists leverage advanced engineering methodologies and industry-standard software to analyze soil-pipe interactions, thermal expansion stress, and dynamic hydrodynamic loading. We are recognized experts in designing specialized piping configurations, including high-pressure rigid pipelines, flexible risers, and insulated Pipe-in-Pipe (PIP) systems for deepwater environments.
Core Fields of Expertise
Route Selection & Optimization
Utilizing GIS routing, environmental surveys, and bathymetry data to select the most cost-effective and low-risk onshore and offshore pipeline corridors.
Mechanical Integrity & Stress
Rigorous calculations for wall thickness, collapse resistance, local buckling, and span correction using international design standards (ASME, DNV, BS).
Pipe-in-Pipe (PIP) & Flow Assurance
Design of thermal insulation systems to prevent hydrate and wax formation in deepwater subsea flowlines, securing flow assurance.
Pre-Commissioning & Life Extension
Detailed procedures for hydrotesting, drying, and nitrogen packing, alongside integrity evaluations to safely extend asset operational life.
Governing Codes & Standards
We operate under strict compliance with global quality and safety standards. Our engineering outputs conform to:
- ASME B31.4: Pipeline Transportation Systems for Liquids and Slurries
- ASME B31.8: Gas Transmission and Distribution Piping Systems
- DNV-ST-F101: Submarine Pipeline Systems
- BS EN 14161: Petroleum and Natural Gas Industries - Pipeline Transportation Systems
