Lifting eyes
Lifting eyes
(OP)
I'm checking a design of lifting eyes of a steel jacket. This is a lift where the jacket is removed from the barge to launch in the sea. There are four eyes fixed lifting the legs of the jacket. The respective eyes have four stiffening gusset. I have doubts about the verification of the local plate legs. I have some references: Blodgett's book, section 6.6, and Roarks. But I doubt the application of these formulations. Could someone help me indicating some article with design examples. I am grateful for any help. Thanks and sorry for my English mistakes.






RE: Lifting eyes
Can you post a picture or drawing of what your talking about?

I am interested to check the stresses in the jacket leg only. Thanks
RE: Lifting eyes
Thanks for the sketch unfortunately I can't tell you alot from the sketch as it only shows one lifting lug and no dimensions, no weight of jacket etc.
Is the cable attached to the lifting lug only acting in two planes?
I can tell you how to check the weld around the lifting lug assuming that the cable is acting only in the two planes and that I assume the weld is a fillet.
Resolve the cable force into a horizontal and vertical force and stress the fillet welds for shear.

Without a lot more detail theres not a lot more I can say.

RE: Lifting eyes
Thanks for your reply.
I am not interested to verify the welding because it is ok. I wanna check the local stesses in the steel leg pipe. I am using the same considerations formulas for hangers and supports. That formulations you can find in the Blodgett Book, section 6.6 (design of welded structure), but I am not sure about it. I ask that because I dont want to model the structure in finite elements. I am looking for a quick manual verification.
RE: Lifting eyes
I don't have that book, can you upload the relevant pages?
You won't break copywright doing several pages.
