Pipeline Engineering Services

Assinov offers comprehensive pipeline engineering solutions that cover the entire project lifecycle — from route selection and feasibility to construction support and as‑built documentation. Our multi-disciplinary team ensures compliance with international codes and provides constructible, safe, and cost-effective designs for cross-country pipelines and associated stations.

We work closely with clients, survey teams, and process engineers to develop optimized layouts that integrate hydraulic analysis, stress checks, civil structures, and instrumentation. Whether it’s for oil, gas, water, or multi-product lines, our pipeline engineering services ensure robust documentation and reduced site conflicts during execution.

Scope: Route alignment, hydraulic calculations, wall thickness & stress analysis, crossing & station design, CP integration, and construction deliverables.
Deliverables: Alignment sheets, route maps, hydraulic reports, wall thickness/stress calcs, HDD/crossing drawings, GA & isos with MTO, CP layouts, and redline/as-built packs.

Service Offerings

• Pipeline route development using topographic, satellite, and field data
• Hydraulic analysis for single/multi-phase flow, pump sizing, pressure drop & surge check
• Stress analysis & flexibility calculations using CAESAR II for above & buried lines
• Wall thickness, span, and support calculation in accordance with ASME/API codes
• Design of river/road/rail crossings using HDD or open-cut methods with protective casings
• Block valve station & scraper trap layout design with access, drainage & safety systems
• Instrumentation, telecom & electrical design for remote monitoring and automation
• Corrosion study and cathodic protection system (anode beds, test posts, bond boxes)
• Preparation of construction deliverables: alignment sheets, BOM/MTO, IFC drawings
• Handover documentation including redline markups and as-built packages

Route Alignment & Survey Integration

Topographical mapping, ROW optimization, satellite overlays, and GIS-linked alignment sheets tailored to site constraints and constructability.

Hydraulics, Thickness & Stress Analysis

Pressure profile & surge checks, wall thickness per code, stress checks for buried/above ground lines, and flexibility analysis for thermal expansion.

Crossings, Stations & Traps

Design of river, road, and railway crossings using trenchless/open-cut techniques; station layouts for block valves, scraper traps, and metering skids.

Cathodic Protection & Documentation

Complete corrosion mitigation through CP design (impressed/anode), test post placement, and delivery of full as-built documentation.
