TL;DR: According to the risk analysis presented in this paper, both the individual and the societal risk level associated with LNG carrier operations lie within the As Low As Reasonable Practicable (ALARP) area, meaning that further risk reduction should be required only if available cost-effective risk control options could be identified.

TL;DR: In this article, a study on various joint models for the simultaneous distribution of significant wave height and zero-crossing wave period is presented, including a conditional model, a bivariate parametric model and several models based on parametric families of copulas.

TL;DR: In this article, an alternative approach for establishing environmental contour lines in the original environmental space is proposed, eliminating the need for any transformations, and the resulting contour line encloses a convex region in the environmental space.

TL;DR: Novel implementation criteria, in terms of the Cost of Averting a Tonne of oil Spilt (CATS), for risk control options aiming at mitigating the environmental risk of accidental oil spills, are proposed.

TL;DR: A novel set of well-defined evacuation scenarios for use in advanced evacuation analyses of passenger ships according to present maritime safety regulations is described and it is demonstrated how the scenarios can be used to relate actual design options to the overall level of risk associated with the ship.
