Wave Data

[jshaw17]

For my project I am working on I have an AH Glenn report which gives me the following wave data:

Significant Wave Height
Significant Wave Period
Maximum Wave Height
Maximum Period
Spectral Peak Period

When determining my environmental loads on a subsea pipeline and riser which combination of of wave height and period should be used to form a velocity profile?

Wave orbital velocities for a pipeline drop with depth and are zero at the mudline, unless the wave is shoaling and bottom currents are developed in the shoaling process. You will have to determine if the maximum wave and period (they go together) is a shoaling wave at the pipeline's water depth.

You should also get the steady current profile data from the Glen report.

Use Significant wave height and period for the stability analysis. The load combination is the worst of 100yrs wave + 10 yrs current or 100yrs current + 10 yrs wave.

Use Maximum wave height and period for the riser stress analysis and free span design.
