Gas hydrate within sediments below the ground holds enormous reserves of methane gas that is increasingly used as a transition fuel from current carbon based energy to a greener future. However, ongoing climate change and production of methane gas from hydrate can have a detrimental impact on slope stability and production infrastructure. Advanced physical and numerical modeling will provide detailed characterization of complex sediment-hydrate interactions under different environmental conditions. This will to enable techniques and technologies to be developed for the safe and efficient production of methane gas from hydrate while also allowing robust assessment of the risks associated with slope instability associated with production and ongoing climate change.

地下沉积物中的气体水合物具有巨大的甲烷气储量，甲烷气体越来越多地用作从当前的基于碳的能量到更绿色的未来的过渡燃料。但是，从水合物中持续的气候变化和甲烷气体的生产可能会对坡度稳定性和生产基础设施产生不利影响。先进的物理和数值建模将在不同的环境条件下提供复杂的沉积物融合物相互作用的详细表征。这将使能够开发出用于从水合体中安全有效生产甲烷气体生产的技术和技术，同时还可以对与生产和持续的气候变化相关的斜率不稳定性相关的风险进行强有力的评估。
