Lessons Learned: Lapse in Navigational Planning Causes Vessel Grounding

5

A vessel on a short voyage ran aground while navigating through a narrow channel at low tide, reports IMCA.

What happened?

Although there were no injuries nor pollution, the incident highlighted a significant lapse in navigational planning and watchkeeping. The vessel was successfully refloated without any damage to hull or propulsion.

What went right?

  • The main engines were stopped immediately after grounding to prevent further damage, and the anchor was dropped to stabilise the vessel until refloating was possible,
  • Emergency checks including tank soundings, draft readings, and surrounding water depth were performed promptly.
  • The Master reported the incident immediately to shore-based management and the local authorities.
  • The members of the bridge team were all fit for duty (healthy, rested and free from alcohol or drugs).

Lessons learned

  • Have a complete and approved passage plan in place, regardless of voyage duration or familiarity with the route.
  • When manoeuvring in confined or shallow waters, have a thorough understanding of local tidal data and under-keel clearance.
  • Stay focussed; know when to politely ask someone to be quiet: Bridge teams should remain focused on navigation and avoid distractions until the vessel is safely alongside.
