Joe, it makes it easier when DDI seems to be involved in so many of these installations - anything one stumbles on seems to have a link to them, LOL. Here's a description of that installation.
"During July 20-29, 2004, the ICCP equipment was brought to Equatorial Guinea, loaded onto a work-boat (Fig 7), brought onsite and installed. As the anode arrays and cables were deployed from the work-boat, floats were attached to the anode cables at predetermined positions to provide the required lazy S curve or catenary configuration of the cable. Constant observation of the installation was provided by live video from an ROV. It was necessary to observe the lowering of the anode array to the seabed (Fig 7) with respect to the cable to ensure that no damage was done to the anode cable during this phase of the installation. Once all the necessary floats were attached to the cable, the cable was then attached to the cable hang off assembly on the ZP (Fig 9)."
