API RP 14c and tubing

API RP 14c and tubing

(OP)
Is it normal to follow API RP 14c for tubing? For subsea chemicals tubing connections are used. However, the shut-in pressure exceeds the subsea design pressure. In my opinion only two options exist:

1) Increase design pressure subsea
2) Install a PSV topside

However, can this be done differently as this is 1" tubing? I.e. an actuated valve downstream the pressure source during shut-in?
