    Summary of geological constraints. Adapted from Mellet et al. (2015)

    Geological featurePotential constraint
    Shallow gas
    • Affects seabed instability (e.g. pockmark formations) and long-term behaviour of sediments (e.g. differential settlement)

    • Can create hard substrates at surface (i.e. methane-derived authigenic carbonates)

    Over-consolidated sediments (e.g. diamicton)
    • High shear strength values make it difficult to pile

    • High levels of heterogeneity

    Exposed bedrock
    • Hard substrate restrictive to some foundation types

    Under-consolidated sediments
    • Low shear strengths affect bearing capacity

    • Implications for differential settlement

    • Prone to scour

    Mobile sediments
    • Can bury structures

    • Can erode sediment at the base of structures, causing instability (e.g. scour)

    • Affect seabed levels
