I have almost zero experience in weld design and I am looking for some guidance. Let me describe my problem. I have a pipe and I need to slip on an annular plate and weld it to the pipe with a fillet weld. The plate is then loaded with a load w that acts concentrically all the way around the...

If a flange assembly has to be made up subsea, is there a special gasket type that must be used as required by code. I seem to remember that there was an API spec that talked about SRX gaskets but they were only used on really small diameter lines. Are regular R and RX gaskets acceptable for a...

Can anyone tell me how long it usually takes for the MMS to approve a Right of Way application for a pipeline. Any references for it? I cannot find anything about it in CFR 30.

For my project I am working on I have an AH Glenn report which gives me the following wave data: Significant Wave Height Significant Wave Period Maximum Wave Height Maximum Period Spectral Peak Period When determining my environmental loads on a subsea pipeline and riser which combination of...

If I am modeling a pipeline laying on the sea floor, how would I determine my spring stiffness knowing only that the soil undrained shear strength ranges from 12-100 psf?

I am looking for any reference material that might help in doing analysis of pipeline crossings. We are putting in a pipeline that is about half a mile and it has 8 crossings. Any papers or books would be appreciated.

I am looking for a method, or spec that will help me very roughly determine the bending stress/strain in an SCR during s-lay installation.

At work we are using this spec DNV-RP-F105 and we are doing the static analysis (section 6.5). I am the intern so I have very little experience with this. So I have a couple questions Can anybody explain to me the sign convention that is being used? How can the internal pressure be negative...

At work we are using this spec DNV-RP-F105 and we are doing the static analysis (section 6.5). So I have a couple questions Can anybody explain to me the sign convention that is being used? How can the internal pressure be negative? And what exactly is meant by the effective axial force? Thanks...
