thanks dear ,

should I check it float in sustain case, and what will be the load case for this . the sea water line is in trench . and depth of top 1.5 mtr . in wave option we need to input marine growth and its density . can anybody explain the line in trench buried than what should I need to input for these value.

but I think wave will come only when line near shore or on jetty trestle , the trench depth is approx. 2.5 mtr .

please guide me how to check pipe lift / float due to buoyancy.

thanks & regards
