Ras Gharib Platform

INSTALLATION TIME: 24 HRS

RetroPod subassemblies were shipped via container to Egypt from Deepwater’s Houston manufacturing facilities. Once unloaded from the container, Pods were erected and welded together dockside. Meanwhile, the Pods’ ballast mattress shells were filled with concrete and attached to the Pods. After lift testing, the Pods and RetroClamps were loaded onto the installation diver-support vessel, Maridive’s Expedition. Once tied up to the platform and after minor debris removal from the seabed, all 14 RetroPods and RetroClamps were installed and commissioned in 20 hours.

Structure potentials were monitored using a diver handheld CP probe as well as a topside-deployed DC-II drop cell (all silver/silver chloride). CP potentials prior to the retrofit were at or near the native state of steel (i.e. (-)0.670 Volts [Ag/AgCl]); after retrofit, potentials ranged from (-)1.050 to (-)1.080 Volts. This was the first retrofit of its kind in the Red Sea and Deepwater is thrilled with the outcome.
