We have had a lot of marine accidents that involved failure of the hull structures. Whether it was a crack in the midship region, or a total split-off of the hull girder, or failures due to propagation of cracks, the crux of the matter boils down to a handful of causes that are of great concern to ship designers and operators. Mostly, crack propagation takes place due to fatigue, which is not something this article is about. This article gives an insight into the causes that lead to the failure of the hull girder from a longitudinal strength point of view. And before we start, we have to ask ourselves a few questions. Why have ships split-off? Why have many hull structures split-off after grounding? Why are midships highly prone to such failures? Is it because of a design flaw? Or for that matter, a glitch in the operation standards that have not been maintained?

The probability of being killed at work is 25 times higher for a coastal fisherman than for an offshore worker, according to a study from the UiS. Seafarers also run a high risk of accidents.
Salvors have been contacted to try and locate the 40-year-ol El Faro boxship which authorities presumed sank near the Bahamas as the ferocious Hurricane Joaquin passed through the region on October 1. Yesterday, the US's National Transportation Safety Board (NTSB) issued a preliminary report on its investigation into accident with scant new details bar the …
The fatal capsizing of the cement carrier Cemfjord off the north of Scotland in January 2015 was almost certainly due poor passage planning and a resulting decision not to seek shelter according the UK's Marine Accident Investigation Branch (MAIB).
As part of its continuing investigation into the sinking of the cargo ship El Faro in the Atlantic Ocean in October, the National Transportation Safety Board has opened the accident docket and released underwater images and video of the vessel.
The expeditions cruise ship Ocean Endeavour suffered hull damages from the ice of Antarctica. The accident happened near the South Shetland Islands with 167
