Specialized tech support (Seabeam, coring, other): 

Other required equipment and special needs: 

Mob/Demob Special Requirements: We will unload the container on the dock and will need a large forklift (> 5000 lbs capacity). We can operate the forklift if allowed, otherwise we will need an operator. Need ship crane support to load equipment on ship (max load 5000 lbs). We will plan to store the empty container on the dock if allowed, otherwise we would need to store on the ship for the experiment.
