Piping Engineering & Pipeline Engineering Services from ProSIM

ProSIM provides engineering consultancy services related to piping engineering and pipeline engineering to host of industries including nuclear, oil and gas, off-shore, thermal power, bio-energy, processing plants. ProSIM provides comprehensive engineering consultancy services during design stage with expertise in design, code check and qualification, analysis, and optimization and design documentation. During maintenance stage, ProSIM provides asset structural integrity assessment services, in-service inspection (ISI) services, remaining life assessment & extension (RLA/RLE) services, fitness for service (FFS), engineering critical analysis (ECA) services, and repair, reuse, retire judgement.

In piping engineering we have worked as consultants to do outsourced / offshored engineering work for operators, EPC contractors, system integrators, technology providers, system integrators and equipment suppliers; as owners’ engineering consultants, and third-party reviewers and assist as engineering experts in legal arbitrations.

In pipeline related services engineering ProSIM provides service to onshore (above ground/ surface pipeline and buried pipelines) and offshore pipelines, submerged pipelines, carrying crude or natural gas or processed crude products.

ProSIM team has skills and expertise in using software such as CAESAR-II, PEPS- PIPESTRESS, CAEPIPE, etc. As per customer request, we have also used pipe elements in software such as ANSYS and ABAQUS to solve some unique problems. Our team has good background of 1D element topology of finite element analysis (FEA), used in pipe stress analysis. Our using our knowledge as needed we can create 3D FEA models of sections of piping and pipelines. We often use sub-modeling approach to combine 1D and 3D FEA models. ProSIM team is fully conversant with relevant international codes such as IS, ASME B&PV, (including ASME B31.1 -power piping, ASME B31.2-Fuel gas piping, ASME B31.3 -process piping), RCC, API, EN, ISO, DNVGL, etc., to carry out the design, analysis, and code check and qualification.

ProSIM has expertise to carry out pipe stress (flexibility) analysis of intricate pipelines used in energy utilities and processing industries. Various loadings such as dead weight, thermal and pressure loads; occasional loads such as wind, ice/snow, seismic, water hammer, steam hammer, ocean current loads are considered during analysis. Benefits of piping stress analysis service from ProSIM are:



  • Design for safe & reliable operations,
  • Increase longevity of piping and equipment
  • Optimised piping layout
  • Optimsied piping supports, hangers, snubbers.

ProSIM offers piping engineering and pipeline engineering services in flexible business models for convenience of our customers.

It can be
  • Outsourced/ off-shored engineering services from our offices in Bangalore, India
  • Onsite consulting services with some resources of ProSIM stationed at customer locations
  • Hybrid models with combination of on-site and outsourced model to give maximum advantage to customers
