Summary

On 3 December 2015 the Panama registered pure car carrier City of Rotterdam collided with the Danish registered ro-ro ferry Primula Seaways on the River Humber. Both vessels were damaged but made their way to Immingham without assistance. There was no pollution and there were no serious injuries.

Safety issues

  • The pilot’s actions resulted from a ‘relative motion illusion’
  • Robust challenges to the pilot’s actions could have prevented his illusion from leading to the collision
  • Off-axis bridge windows and lack of visual references led to pilot’s disorientation
  • Ergonomic impact of innovative bridge design not fully assessed

Recommendations

Bureau Veritas, City of Rotterdam’s classification society, has been recommended (2017/104 and 2017/105) to propose measures to the International Association of Classification Societies that are aimed at raising the awareness of relative motion illusion and promoting the need for naval architects and shipbuilders to adhere to internationally accepted ergonomic principles for bridge design.
