The RH side of the long panorama is obviously mirrored, both because of the reversed lettering on the containers and the wrong perspective of the cranes.
Edit out the center two cranes.
Copy the end cranes to the positions of the two you removed
Copy the single visible leg of each of those and use them to replace the leg half hidden by the other structures
Select all of the containers on the left side of the panorama, Use the "SKEW" tool to level the horizon line of the containers.
Copy the containers on the left and paste on right side
Selectively edit containers, copy/pasting over the joint between the two halves, alternating like laying bricks if possible.
