Hi all,
I´ve just started in a oil and gas company, already throwed to the wolves
In this moment I am calculating the capacities of a subsea tubing hanger running tool layout that I defined a long with my colleagues, in terms of loading shoulder capacities, stres analisys and pressures vessels.
My questions are:
1- is there a guide in the standards API 6A/ISO 13628 or do you have a calculation excel sheet based on them, in order to calculate the maximum load shoulder capacity of a certain body, concerning shoulder angle, material, contact area...?
2- the layout will be composed by a main body and then several pistons and specific guides for locking. Those pistons will move, due tu applied pressure through specific hydraulic line. I will have to calculate not only the necessary pressure to move the piston, but also if the guide wall will support the stress of the applied pressure. What should be the security factor to apply, between the maximum pressure and the maximum ID (therefore less material possible) considering the yield resistance of the material? Basically is a OD/ID calculation, applying a maximum pressure inside the body...in a material with 105 ksi, what should be the security factor? Should I only consider for example like the material had 90 ksi?
This would be a great help, have to prepare a DR for next week
Thank you
