Ship grounding

The St. George Island, Alaska

Ship grounding is a type of marine accident that involves the impact of a ship on seabed or waterway side.[1] It may result in the damage of the submerged part of the ship’s hull and in particular the bottom structure, potentially leading to water ingress, which may compromise the ship's structural integrity, stability, and safety.[2][3] Severe grounding applies extreme loads onto ship structures.[4] In less severe accidents, it might result only in damage to the hull; however, in most serious accidents, it might lead to hull breaches, cargo spills, total loss of the vessel, and, in the worst cases, human casualties.[5]

From a global perspective, grounding accounts for about one-third of commercial ship accidents all over the world[6][7] and it has the second rank in frequency, after ship–on–ship collision.[8]

Grounding, depending on the maneuvers of the master before the impact, may result in the ship being stranded. Depending on the nature of the relief of the seabed at the location, i.e., being muddy or rocky, different measures have to be taken to release the ship and transport it to a safe harbor.

Investigating the causality of grounding accidents, there are many factors that are believed to contribute to the accident, such as current,[9] darkness,[10][11] tide,[11] visibility,[6][7] wave,[9] wind,[6][7][9] depth [6][7][12] and geometry of the waterway;[9][11] age,[8] size [6][7][8] and type of the vessel;[6][7] speed,[12] and human and organizational factors;[6][13][14][15][16][17] However, the effects of most of the causal factors have been considered anecdotal, without evidential support.[18][19]
