Background information and definitions
Pipelines and infrastructure from offshore industry structures, such as oil and gas, renewable energy, and mining can impact subtidal benthic invertebrates through physical damage and loss of habitat when the infrastructure is constructed, but also following decommissioning through indirect environmental impacts, such as chemical leaching and corrosion of structures (Picken et al. 1997). Removing structures is one decommissioning option to remove the threat from the marine environment (Brigitte et al. 2018; Chandler et al. 2017). In the OSPAR maritime area for instance, the at-sea disposal or leaving in place of disused offshore installations is prohibited (OSPAR 1998).
