I found it in an article related to umbilical, oil industry.
i know psi stands for pounds per square inch, but what's wp then?
Here's the text where I found it:
IWOCS and THRT umbilicals for ultra deepwatwer applications, for pressures for up to 15,000 psiwp....

Well, like everyone else said, I know psi is pound per square inch. I found a few things WP could stand for but I think the definition you're looking for is WP stands for working pressure. It may not apply to the topic you're talking about but I hope it helped a little.

PSI is probably pounds per square inch. Not sure about WP.

I believe that you owe GraceB 10 glorious points for wp = working pressure. Also if you place "psi wp" (using quotes) in a search engine you will get many hits as it is a common phrase. Add working pressure (without quotes) and it will narrow your search. I used google. Good luck.
