Pipeline design and engineering software
Spectrum Pipelines® makes pipeline design smarter.
A pipeline design and integrity software suite, developed by SK Eng. in association with Z-Subsea Energies. 13 modules cover the calculations pipeline engineers run on every project, from line sizing and wall thickness to free spans, buckling, corrosion and remaining life.

Popular modules
The modules
13 modules. One suite.
Each module follows the codes and recommended practices you already design to. Start with the ones you need and add others later.

Main features
Built by pipeline engineers, for pipeline engineers.
One suite for the whole range of pipeline design and integrity calculations, written by engineers who run them on real projects.
By pipeline engineers, for pipeline engineers
Developed by engineers with more than 20 years’ experience in the oil and gas pipeline industry, who know what a pipeline engineer needs from a calculation.
Best practice built in
Years of project experience are coded into the software, so it doesn’t just give an answer: it gives one based on best industry practice that makes engineering sense.
Guidance on every input
Each input has a help window suggesting the expected value, based on best practice and the judgement of the experienced engineers behind the software.
Concise, printable results
An easy-to-use interface takes you through each calculation and shows the results on one concise screen that you can print or save.
Buy only the modules you need
The suite is modular. Start with the module you need today and add others as and when your projects call for them.
Modules that work together
Results pass from one module to the next, so related calculations stay consistent across a project.
Linked modules
One calculation feeds the next.
Spectrum-Flow Assurance generates the data Spectrum-Corrosion needs for its corrosion rates, and Spectrum-Integrity uses those rates to calculate a pipeline’s remaining life.
