Arnold / Oyster Fields
Anode retrofit for two deep-water GOM subsea field developments
Deepwater Retroclamp was designed for rapid installation by ROV on pipelines.
Deepwater Corrosion Services performed anode retrofits on Marathon's "Arnold" and "Oyster" fields in the Gulf of Mexico. These two subsea development systems, located in water depths ranging from 775 to 1,750 feet, were retrofitted in just over 73 hours. Assets to be protected included:
• 4 flowlines, ranging in length from 3 to 9 miles each
• 4 well trees
• 2 flowline manifolds
• 2 umbilical termination units
The cathodic protection (CP) system consisted of:
• 19 RetroPods (Aluminum sacrificial anode sleds)
• Various standard and customized RetroClamps for electrical attachment.
