Catenary app has been developed as a quick and useful tool for installation engineers, installation analysts, riser engineers and others working in the offshore Oil & Gas industry. This application can be used in meetings or elsewhere as a quick reference tool to obtain numbers on Steel Catenary pipelines instead of going to a desk pc to obtain the requisite information. The user is required to input a few details about the pipe in question, the water depth, hang-off angle (w/ vertical, for e.g. 4.5deg) and if required dynamic amplification factor to obtain catenary top tension, bottom tension, catenary length and layback distance.

In the current version, the app is in English units only and includes the above mentioned results only. In future versions, a choice between Metric and English units will be added, flexible risers and umbilicals will be added and based on user feedback more results will be incorporated. For more accurate results, an FEA analysis should be performed and this app's intent is to be used as a reference tool only.

Just wat the subsea doctor ordered

Awesome app for me as a subsea professional. Thanks Bharani.

5/5 stars


Found it handy for quick reference for discussions and estimations. I would like other results such as pipe weight per foot or meter and linear submerged weight as well. But five stars for the great idea, keeping it free and intent to improve it.
