Lights..Those lights were part of the site prep ......what I would be doing is to use steel sheet piles and dredge the enclosures with river silt ....cap the dock with a couple of feet of concrete .....install bollards to tie up .....that would be structurally strong enough to support a container ship .....what's there now is not ....my guess is this is just the access dock to the main dock .....a container ship has a huge amount of mass that would have to be supported ....that dock will not do it .....
