Factor of safety for composite pressure vessel
Factor of safety for composite pressure vessel
(OP)
I am designing a subsea composite pressure vessel (mainly loaded under external pressure). Can somebody provide me information about the factors of safety that need to be applied. I suppose it most be more than 1.5, due to the underwater environment and the unknown influences it can encounter. The purpose of the vessel is to deliver buoyancy in a range between 500 m and 3000 m below sea level.
Thank you in advance, it would be of great help.

A composite shell requires careful design: particularly under external pressure. Shell length betwwen stiffeners is governing factor for resisting pressure - sort of holds the section circular.
In the Uk we use BS4994:87 and the MINIMUM K factor is 8 and frequently in the range 8-14.
Trust this is of help.

Wow, 8-14 seems a lot!!!!
I will surely check out the Codes...
