EM&I installs diverless anti-corrosion system on FPSO

A completely diverless system for protecting underwater hulls from corrosion has been installed and is operating successfully on an FPSO in the UK North Sea. This innovation means operators around the world can be safer whilst reducing costs and carbon emissions by deploying the HullGuard system.

Designed for lifetime protection of the underwater hull from corrosion, HullGuard is an EM&I innovation that involves installing a tubular ‘periscope type’ anode with an integral dielectric shield, through an ODIN® type class approved access port fitted to the inside of the ship’s hull.

Once the anode is installed the launch tube is removed leaving only the completion plug in place with the electrical supply cable ready for connection to any suitable transformer rectifier system.

HullGuard can be installed and maintained at any stage in the asset’s life, either from new or retrofitted using a 3 – 4-person team. This compares with a weather dependant 15-person dive spread, associated support vessels and significant carbon emissions.

Danny Constantinis, EM&I’s Executive Chairman, commented: “EM&I’s mission is to reduce risk, cost and carbon emissions in the energy industries. Reducing diver interventions and personnel working at height or in confined spaces are initiatives where we have already made great in-roads and HullGuard is a further important step in this direction.

The future is using robotics, digitisation and technology to drive this transformation, and I am confident that this solution will be welcomed in a market which seeks safer, lower cost and lower carbon footprint solutions.”
