- A novel 3D methane bond model able to replicate the experimentally observed behaviour of methane-bearing sands was formulated. The ability of 3D DEM simulations to predict the mechanical behaviour of the sands was rigorously validated against experimental data from literature for a variety of physical conditions. Suitable modelling of methane-bearing sands is essential to device safe methods to extract this alternative future energy source from seabed deposits avoiding subaqueous slides. Rival research groups in China, Israel and Japan are using the work to model seabed stability. The paper was instrumental for the award of €2.1 million EU project ‘Geo-ramp’ https://cordis.europa.eu/project/id/645665.
