Pipeline Stability
Pipeline Stability
(OP)
I'm currently peforming a subsea pipeline stability analysis. In previous anaylses I have performed, increasing the lateral friction coefficient increases the stability- as to be expected. However, in several cases the stability is decreasing when I increase the friction. It is in relatively shallow water (35m) and I'm thinking this may have something to do with it, but cant come up with a reason- although I'm sure its fairly straightforward- could anyone explain this for me so that I can start kicking myself......

Isn't it still U.S. std. practice to bury (petroleum lines) when water depths are less than 200 ft?

As you go shallower, the hydrodynamic forces increases and also the wave theories changes, refer Shore protection manual for applicability, some programs do this automatically.
