McDermott — subsea cathodic protection survey
Post-installation CP survey of 120 km of subsea pipelines and 250 subsea inline structures across multiple satellite drilling centres, using IICORR's patented IoT Multielectrode device and ROV integration.
The problem we solve
McDermott required post-installation CP surveys of over 120 km of subsea pipelines and 250 subsea inline structures across multiple satellite drilling centres during an installation campaign — with subsea-asset integrity critical to environmental protection and project success.
Our approach
- 01Deployed IICORR's patented IoT Multielectrode device for continuous CP potential and field-gradient measurement
- 02Integrated with McDermott's LV108 work-class ROVs
- 03Real-time data transmission with video-overlay during the campaign
- 04Synchronised logging and offshore interpretation as the survey ran
