ABSTRACT
Cryogenic spills are considered a risk for floating LNG units (FLNG). However, it is difficult to quantify these risks and formulate adequate strategies for counteracting them. Therefore small-scale laboratory experiments have been done to observe the formation and growth of cracks under a spill of liquid Nitrogen, as model for an LNG spill. These experiments have also been simulated through FE modelling in combination with LEFM, to show that such techniques would be adequate for the simulation of crack development. Similar modelling has then been applied to the maindeck area of an FLNG hull subjected to cryogenic spill. Application of cryogenic spill protection is investigated.
