Ship grounding or ship stranding is the impact of a ship on seabed or
waterway side.[1] It may be intentional, as in beaching to land crew or cargo, and careening, for maintenance or repair, or unintentional, as in a marine accident. In accidental cases, it is commonly referred to as "running aground".
When unintentional, grounding may result simply in stranding, with or without damage to the submerged part of the ship's hull. Breach of the hull may lead to significant flooding, which in the absence of containment in watertight bulkheads may substantially compromise the ship's structural integrity, stability, and safety.[2][3]
Severe grounding applies extreme loads upon 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]
Grounding accounts for about one-third of commercial ship accidents,[6][7] and ranks second in frequency, after ship-on-ship collision.[8] Grounding accidents are being studied in many international ports with serious concerns, e.g. Chittagong Port in Bangladesh.[9]
When accidental grounding occurs, the ship or its cargo, will need to be removed if possible. This is done for various reasons:[citation needed]
The grounded ship remains seaworthy so the ship is removed in order to be repaired and return to service
A stranded ship is unsightly
A stranded ship experiences significant stress on its structure and will eventually become a shipwreck if not properly dealt with
The ship contains hazardous material and can cause environmental damage if the material is released, which will eventually happen if stranded long enough
A ship might be removed to prevent unauthorized entry into the ship by locals
The grounded ship is a navigation hazard or otherwise obstructs a shipping route
