Are there any popular forums about offshore and soil mechanics?

What about this one? I had a look and it seems safe to use, quite active and hopefully will have some people who can help you with your questions.

On Fluther we have many experts on many subjects but it seems that there are no experts on soil mechanics. Maybe once you have studied some more, you can come back and be our expert? But please do stay and participate in some other questions and answers. We welcome new people.
