Background information and definitions
Stabilisation material, such as concrete mattresses and rocks (rock dump), can be used to keep pipelines and infrastructure (from offshore industry structures, such as oil and gas, renewable energy, and mining or aggregate extraction) in place and may also help to protect the infrastructure (for instance from fishing gears) by covering them. Stabilisation material may need to be recovered following decommissioning, and their retrieval might cause additional physical disturbances to the seabed and to subtidal benthic invertebrates. Stabilisation materials designed to be easily recovered at the decommissioning stage can help reduce the level of habitat disturbance associated with this process. Evidence for interventions related to the decommissioning of offshore infrastructures and pipelines are summarised under “Threat: Energy production and mining – Remove pipelines and infrastructure following decommissioning” and “Leave pipelines and infrastructure in place following decommissioning”.
