hi every one,
The overbend is displacment controlled, because it conforms to the stinger geometry, therfore strain based deign (SBD) can be used (Equation 5.25 and 5.26 of DNV OS-F101 Sec. 5)
Now to the sagbend: Regarding that its curvature is a function of tensioner force, can one still assume...
assume u have a thin walled steel cylinder (1 m Dia and 10 m length for example). it is anchored to the seabed. if the water depth in the location is 2000 m, the cylinder will probably be crushed by hydrostatic pressure.
now assume you let a stone submerge in an ocean with infinite depth. the...
I am starting my graduate research.
It should be something about subsea pipelines.
Is it common to consider Vessel motions during pipelaying?
Or are the stresses during installation considered in an unrealistic static condition?
Do you think the considering vessel motions will result in very...
thanks guys,
The lifting photo was amazing.
I had seen spreader bars for deck lifting, but not "spreader truss"
I meant the spool piece which is used at the connection of a subsea pipeline to riser...
I think I read somewhere in the 21st edition that API has concluded LRFD is not suitable for Platforms... I guess the main cause was mentioned the great number of uncertainties involved in the design...
So -happily for me- WSD is going to be used for decades to come!
