Brazil’s state run energy group can monitor hydrocarbon flows through one of its huge oil fields in the Santos basin with a sensor grid using a DOF vessel
Petrobras has deployed a reservoir monitoring grid on its giant Mero oil field in the Santos basin offshore Brazil in a “first-of-a-kind” operation.
DOF subsidiary Maersk Supply Service installed the dynamic cable riser using a specialised module on 2017-built subsea construction vessel Skandi Involver. This enabled it to connect to a permanent reservoir monitoring (PRM) sensor grid on the deepwater field.
DOF installed a spread, manufactured in Scotland, on this Marin Teknikk 6027 design, 138-m vessel for the Mero PRM, which will enable Petrobras to monitor oil and gas flows through the reservoir and plan future developments, infill drilling and secondary and tertiary recovery planning.
Maritime Developments Ltd (MDL) developed the bespoke spread to simultaneously handle five individual cables and the dynamic cable riser, and to install the data transfer unit assembly pigtails and backbone cables – all deployed from 9.2-m reels. This was mobilised in Peterhead, Scotland, and installed onSkandi Involver.
