Pipelines & Infrastructure

Pipeline design

Our team have worked on projects that have included:

Stress analysis of GRE suction and discharge header piping to BS 7159 up to size DN1000, calculation and review of piping loads on pumps, filters and supports, stress analysis of HDPE pipe.

DN450 Crude Oil Pipeline Re-Rate,

Stress analysis for the re-rate of an existing 7km long crude oil pipeline to AS2885.1, and utilising buried pipeline modelling in CAESAR II.

Concept study for a HDPE has gathering system and spine line,
