If we have a water filled horizontal pipe on seabed with 200 bar in it.
And boat with a flexible downline is connected to the pipeline in 100m of water depth.
a) If the vessel bobs up and down by 5m I think that the pressure in the pipeline read at vessel changes by 0.5 bar each way, due to the vessel moving up and down on a virtual 2000m long hydraulic grade line?
b) But subsea the pressure in the pipeline does not change, since the pipeline position does not change on the virtual hydraulic grade line?
Are a) and b) correct?
Thanks
