Research on hydrodynamic interaction indicates that if the speed of the ship near a bank is too high, the rudder may be less able to cope with the forces induced and control will be lost. The Nautical Institute highlights this in its latest Mars Report, in which an LPG carrier hit a barge being towed by a tugboat as a result of hydrodynamic forces.
The operators of Egypt's Suez Canal say technical or human error could have caused a huge container ship to run aground. Engineers are working round the clock to refloat the Ever Given. The vessel has been blocking one of the world's busiest shipping lanes for the last five days. The chairman of the canal authority hopes a dredging operation will free the ship in the next few days.
