Intervention

Ensuring intervention is carried out efficiently and cost effectively

Troubleshooting issues and replacing components subsea is common during operations. Understanding and planning for the various challenges which may hinder the intended intervention will allow operators to minimise the vessel costs and system downtime associated with subsea interventions.

Many problems arise from the formation of calcareous deposits as a by-product of the cathodic protection system which hinders the removal of items subsea. For more information on the formation and removal of calcareous deposits, check out our science of stuck series here.
