Hello,
I am thinking of the best approach on carrying out on-bottom stability of a 4-inch gas lift line being piggybacked by a 12-inch main pipeline:
-Analyzing just the stability of the 12-inch main line (ignoring the piggybacked line) or
- calculating the equv. WT of both lines , then using...

Hello Everyone,
I have not actually gotten my hands on the latest API 5L Specification for Line Pipe, 5th Edition and was wondering if anyone has done a detailed comparison between these two revisions (44th and 45th). Please it will be so much appreciated.
Hello,
I am currently making some sensitivity runs on-bottom stability using AGA level 2 for a subsea pipeline , at 20 meter water depth.
However , I am getting a strange result which I can’t explain:
Taking a typical Case;
Current dominant case, with Spectral Peak Period (Tp) = 13.6s...

I am carrying our a shore approach design for a 20in gas line. The pipeline will be trenched and backfilled (1 m cover) with sand.
Please I am looking for calculation methods/go-by for assessing the stability of the pipeline/backfill against hydrodynamic forces.
I have just calculated axial friction factor of a pipeline laid on a soft clay based on three parameters; breakout friction, residual friction and remolded friction...Residual friction gave me lowest value while breakout gave me the highest value (Ref OTC 19589 PSI during lateral Buckling and...
Hi
I am currently working on thermal expansion analysis based on Palmer and Ling theory
for a 75km offshore pipeline.
I want to know if its the DESIGN OR OPERATING TEMPERATURE PROFILE I should use for
my calculations, because my PROCESS team supplied me with just the operation temp profile...
I need help writing the statement below on mathCAD
C1= 0.2 when beta is less than or equal to 0.9
C1= -0.2 when beta is equal to 1.0
linearly interpolating values between b=0.9 and b=1.0
( please refer to the attached for further clarification)
Thanks
I will be going for a site visit of an existing offshore platform which is to be linked to another platform (proposed) via a bridge connection.
Please does anyone have a typical verification checklist from a structural point of view?
