SubC Partner recently won an EPCI project on an FPSO with Maersk Oil in the Dumbarton field in the North Sea, 230 kilometers northeast of Aberdeen.
The final goal of the project is to replace selected buoyancy modules on a live riser, without shutting down oil production, the company said.
“ We are delivering a turnkey solution from the engineering phase where we develop the tools we need for this specific project, to the offshore operations where we will be replacing selected buoyancy modules via ROV (Remote Operated Vehicles), ” Gabriele Rampinelli , UK Managing director at SubC Partner, says.
The EPCI project for Maersk Oil should make a significant contribution to optimizing asset performance operationally and economically, SubC said.
“ Traditionally you would have to disconnect the riser to replace buoyancy modules, which means that the FPSO will not be able to process oil while we work on the riser, ” Gabriele Rampinelli says.
He continues: “ In this case we are able to work on the FPSO riser without shutting it down because we work with ROV. ”
The ROV and the special tooling is operated from a DP2 vessel, which is positioned outside the swing circle of the FPSO. This ensure no production down time while repairing the riser.
