Pipeline engineering entails complex multidiscipline work responsible for developing all elements and systems required to guarantee the success of a project.

We are specialists in the following areas:

  • Simulation

  • Selection of pipeline technology, materials, and constructive characteristics

  • Analysis and follow up of topographic studies and hydrological risks

  • Development of planimetrics and special crossings

  • Automation and telemetry of line break valves

  • Selection and specification of gas detection systems

  • Cathodic protection systems design and photovoltaic generation

Pipeline operation is a core discipline which must be considered from the beginning of a project to deliver straightforward ducts with no future operating problems.

Flow Assurance is a technique applied to  multiphase pipelines with a wide range of liquid/gas ratios, from gas with water-condensate pipelines to very low GOR crude oil flowlines, particularly in the definition of adequate procedures for safe operational changes such as start-ups, rampups, shutdowns, and re-startups.

Flow Assurance allows evaluation in the transient mode of operations such as:

  • Glycol injection scheme to avoid hydrate formation during initial startup with surrounding grounds still cold.

  • Evaluate optimal pipeline diameter to avoid flooding or generation of big slugs during a variety of operations.

  • Verification of capacity and control loops of existing slug catchers.

  • Slug generation during rampups. maximum rampup speed (ramp / staggered) to prevent slug catcher flooding.

  • Alternatives for scrapping / pigging procedures with limited slug catching capacity.

  • Packing, cooldown and hydrate risk after shutdown. Determination of "no-touch time" to perform a safe hot restart.

  • Hot re-startup with packed line and flooded valleys.

  • If hydrate risk zone is entered, sequence for depressurization and cold re-startup.

  • Other range of related results:

    • Corrosion studies (Conventional, Top Of Line).

    • Transient safety studies (e.g. evaluation of sudden depacking towards inlet separator).

    • High pourpoint pipelines. Design of thermal control schemes. Paraffin deposition analysis/prediction.
