Ship grounding is the impact of a ship on seabed or waterway side.〔Mazaheri, A., Montewka, J., Kujala, P., (2014), "Modeling the risk of ship grounding - A literature review from a risk management perspective", WMU-Journal of Maritime Affairs, Vol. 13, No.2, pp.269-297, doi: 10.1007/s13437-013-0056-3〕 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. 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.〔Mazaheri, A., and Ylitalo, J., (2010), “Comments on geometrical modeling of ship grounding”, 5th International Conference on Collision and Grounding of Ships (ICCGS), June 14th - 16th, Espoo, Finland〕〔Montewka, J., Krata, P., Goerlandt, F., Mazaheri, A., Kujala, P., (2011), “Marine traffic risk modelling - an innovative approach and a case study”, Proceedings of the Institution of Mechanical Engineers, Part O, Journal of Risk and Reliability, Vol.225, No.3, pp.307-322, doi: 10.1177/1748006X11399988〕 ==As hazard== Severe grounding applies extreme loads upon ship structures.〔Pedersen PT Collision and Grounding Mechanics. In: Proceedings of WEMT '95', Copenhagen, Denmark, 1995. The Danish Society of Naval Architecture and Marine Engineering〕 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.〔Mazaheri, A., Goerlandt, F., Montewka, J., Kujala, P., (2012), “A decision support tool for VTS centers to detect grounding candidates”, International Journal of Marine Navigation and Safety of Sea Transportation, Vol.6, No.3, pp.337-343〕 From a global perspective, grounding accounts for about one-third of commercial ship accidents,〔Kite-Powell HL, Jin D, Jebsen J, Papakonstantinou V, Patrikalakis N (1999) Investigation of Potential Risk Factors for Groundings of Commercial Vessels in U.S. Ports. International Journal of Offshore and Polar Engineering 9 (1):16-21〕〔Jebsen JJ, Papakonstantinou VC (1997) Evaluation of the Physical Risk of Ship Grounding. Massachusetts Institute of Technology,〕 and ranks second in frequency, after ship–on–ship collision.〔Samuelides MS, Ventikos NP, Gemelos IC (2009) Survey on grounding incidents: Statistical analysis and risk assessment.
