Ship collision is a type of maritime incident that occurs with the structural impact between two ships or one ship and a floating or still object such as an iceberg.[1] Ship collisions are of particular importance in marine accidents. Some reasons for the latter are:

As sea lanes are getting more congested and ship speeds higher, there is a good possibility that a ship may experience an important accident during her lifetime. Higher speeds may cause larger operational loads, like slamming, or excessively severe loads, for example during a collision. Denser sea routes increase the probability of an accident—in particular a collision—involving ships or ships and shore or offshore structures.[citation needed]

Almost 27% of ship collisions occur near coasts and 22% at narrow channels.[2] This is due to disregarding best practices and regulations by navigation officers and masters. In addition, the IMO guidelines for voyage planning are not always followed. Violations usually occur when inadequate safe speed, overtaking or miscommunication with the pilot.[3]

Collisions with wildlife

Further information: Environmental impact of shipping § Wildlife collisions

Large whales and species like sea turtles or whale sharks often suffer lethal wounds from collisions with ships ("ship strikes").[4][5][6] There are programs in development and implementation phases, aimed at reducing vessel speed in critical waterways, both voluntarily and by regulation, which aim to protect endangered whales.[7]

Collisions between cetaceans and vessels – known as 'ship strikes' or 'vessel strikes' – are a significant cause of death and traumatic injury for cetaceans. And these accidents are likely to become more common in the future due to the increasing amount of traffic on our seas, and the increasing size and speed of today's ships.Tackling this threat to the world's cetaceans is hampered by the fact that under- or non-reporting of ship strikes is still the norm around the globe. ... Since its creation in 2009, more than 1,200 incidents have been registered [until 2014].
