The crane unloads cargo onto the Mersey quayside during high tides, providing increased space for vessels to reach the seawall.

*Liverpool docks to ship movements impacted by the Mersey tide and waves.*
The 61 meter tall crane on the Mersey ferry has a tough job of unloading cargo onto the dock.
The sea tide rises and falls everyday, the difference being about five meters, or just under 50 feet or about four stories, in height. This can cause shifts and movements to the docks. One such movement is caused by high tide and low tide.
As the mercury continues to rise at the top, so does the water level. When it reaches a point, the water begins to flow out of the tide pool due to the low points below it. As a result, vessels will be able to come nearer to the quay to unload cargo. The distance from the dock to the seawall at one end is approximately sixteen meters or fifty-three feet. However, this will not prevent ships in need to find their own way through the waters. In addition to this tide caused movement, there are waves and currents that make it difficult to navigate, especially while trying to dock. To ensure effective docking, the ferries must be equipped with advanced technology.
