PIPELINE ENGINEERING
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.
