Vessel movements

Why do they matter?

Moored and Berthed Vessel Movements

When a ship is attached to the shore, we call this mooring. When the ship is positioned at a specific place along the quay, we call this berthing. In both cases, the ship is attached with cables or ropes to keep it into place.

When moored or berthed, ships tend to move due to tides, met-ocean factors or the passing of other ships nearby. These movements occur in 6 degrees of freedom (DoF), of which the forward and backward movement of the vessel, surge, is the most problematic one.

Problems Caused by Vessel Movements

As the size of ships have been increasing steadily, to accommodate the ever-augmenting quantity of goods moved around the globe, they have come to put a larger strain on the port’s infrastructure. The movement of large vessels can cause concerns such as:

  • Broken mooring lines
  • Damaged mooring hardware/fenders
  • Damaged vessel hulls and loading equipment
  • Environmental risk such as fuel spills
  • Interruption of operations
  • Injury or death of personnel

How to contain vessel movement related risks

Unfortunately, it is not always possible to adapt the port or terminal infrastructure to the increasing forces exerted by giant vessels. At most, the movements can be monitored to collect data that give insight into the causes of ship movements, and to alert all stakeholders when vessel movements cause a risk.

Monitoring vessel movements has been a harder nut to crack than originally expected. Fortunately, now MoraSense has developed the ultimate solution to obtain reliable data in real-time.
