Abstract
Rock-filled mesh bags is an appealing method for both temporary and permanent stabilization in the offshore environment due to ease of installation, however, there is limited empirical evidence as to their performance which makes assessment of design safety factors challenging. The present work derives a critical mobility number for a singular rock-filled mesh bags far from any other infrastructure, and its expected failure mechanism: Sliding or over-turning. The critical mobility number is established through an experiment with individual rock-filled mesh bags in waves-only and current-only conditions, respectively. The rock-filled mesh bags are placed on both smooth and rough seabed. Engineering guidance is offered on how to extrapolate findings to the stability of the rock-filled mesh bags in (i) combined waves-and-current and (ii) in the proximity to offshore structures.
