DNV-RP-F109 : Meaning of SEED?

DNV-RP-F109 : Meaning of SEED?

DNV-RP-F109 : Meaning of SEED?

DnV-RP-F109 Sec. 3.4: what is the meaning of SEED?

RE: DNV-RP-F109 : Meaning of SEED?

I want to say "seed" is a random number. May be wrong. Might want to ask DNV.

RE: DNV-RP-F109 : Meaning of SEED?

Furthermore, in ORCAFLEX to define wave type JONSWAP, there is an option named SEED. What does SEED mean in either DNV-RP-F109 or ORCAFLEX?

RE: DNV-RP-F109 : Meaning of SEED?

The Jonswap SEED in Orcaflex is used to define the pseudorandom irregular wave.

This means that although an irregular simulation is 'random', it can be repeated - e.g. the seed 12345 will always give exactly the same wave train.  

The meaning is the same in RP-F109.

Hope this helps
