Pipelines Engineering

Pipelines Engineering

Major Pipeline Engineering activities include, Route selection, design calculations such as wall thickness, road crossing, stress analysis, preparation of data sheets, specifications, Material Requisitions for all pipeline items. We executed projects for over 2500 km of Oil/Water Pipelines and 1825 km Gas Pipelines. Pipeline engineering design services include

  • Desk top study for routing of the pipelines based on Google earth and site visits to select the pipeline routes.
  • All local government / authorities approvals for the selected pipeline route with the support from the clients.
  • Preparation of reports such as Pipeline design basis, location class study, burial philosophy, route selection report, material / grade selection report, crossing schedule / Matrix etc.
  • Carrying out the Pipeline design calculations such as Wall thickness, Road crossing, Buoyancy, Hydrotest pressure, wall thinning, elastic bending, branch reinforcement, anchor block forces, flange joint leakage, Buckling and crack propagation, Fracture toughness, stress analysis of above ground / buried pipelines using CAESAR II software etc.
  • Specialized pipeline design calculations for Upheaval & lateral buckling by OTC 6335 and by K.Peter’s method & Hot tap feasibility calculations based on Shell DEP.
  • Preparation of  Data sheets, Specifications and Material Requisitions for all Pipeline items such as Linepipe with external coating ( 3 LPE / 3 LPP) , pig traps, Isolation joints, ball valves, heat shrink sleeves, throkote sleeves, pig signallers, slimline valves, induction bends for  CS / SS/ DSS / CS – Inconel cladded, CS – PE lined, CS- FBE coated material of construction.
  • Preparation of Technical Queries, Technical bid analysis, Vendor drawing reviews
  • Preparation of Alignment sheets, routing drawings, pipeline detail drawings for road crossings (Tarmac / Graded / Livestock), Wadi crossings ( Type- A, B, C), Marker plates, all utility  crossings,, plot plans, Piping plans and Isometrics, MTO.
  • Specialized in preparing the alignment sheets based on satellite survey.
  • PDS / PDMS Modeling
