ASME BTH is the most thorough standard I've seen for pinned lifting connections, it references papers where the calculations are compared to test results.
Anyone who knows what they're doing solves these problems with hand calculations.
To do this with FEA would require the clevis, pin and the...
In case it was missed. I could find every other article from that edition of the journal but the relevant one. Maybe someone else's google fu will be better.

Maersk Alabama was US flagged for a time but was never Jones Act eligible.
There's a program to subsidise bringing private ships under the US flag so they're available for sealift (effectively an admission that the Jones Act failed in its purpose). But the Jones Act restrictions are still in force.
The issue is the foreign ship can't pick up containers in SF and offload them in SoCal. So containers will never be moved by ship between those locations, only by road or rail.
There's no prospect of the act going away, the cost is distributed amongst everyone and there's a strong lobby in is...

The charges were later detonated using a sonar buoy dropped by an aircraft.

I really hope the convoluted conspiracy theories here are just larping. UFO theories sound quite reasonable compared to the Russians blowing up three pipelines - including two operational ones - so they can get one pipeline operational.
Regarding the repair - if politics allow - of the pipeline. It will be done in much the same manner as the different sections of the pipeline were connected originally.
The 1,200km pipe wasn't installed in a single operation, instead three sections were installed and then connected subsea (the...
Some pictures of the pipeline. Obviously there isn't 50m missing as per the article, tension in the pipeline will have caused it to move after being severed.
The design life was 50 years, no reason to believe it couldn't last longer if properly maintained. It's just a question of politics whether or not the pipelines will be repaired.
