Wages/Benefits for Local 25/dredging

Hey all,

Looking to find any wage/benefit information for local 25 and if its worth getting into. Im currently a dockbuilder but would like to advance my maritime experience with my offshore activity. That being said I have a TWIC, MMC with an OS/Wiper endorsement, OSHA 10, OSHA 30, and numerous welding certs. Is there anything else I am missing in order for me to get into dredging? Thanks in advance!
