The element, which is 217m long and weighs 73,000 tonnes, has been filled with an additional 4,500 tonnes of ballast concrete.
Femern Link Contractors will connect the element to the pontoon vessel IVY for extra buoyancy before it is towed out by tug boats.
It is the first of 89 elements that will form the new fixed link between Lolland in Denmark with the German island of Fehmarn.
The work inside the element has been carried out via a temporary access structure consisting of five shafts, which are bolted onto the watertight steel bulkheads that keep the water out. At one end there is a materials lift, a concrete shaft and a man‑access shaft, which also functions as ventilation. At the other end there is a ventilation shaft and an emergency shaft for personnel.
When the filling has been completed, most of the equipment will be removed, the doors in the steel bulkheads closed, and the element made ready for tow‑out.
