Riser Access Tower (RAT) was designed to allow the connection of new small prospects nearby the existing assets to an existing host platform. The intention of the design is to minimize the brownfield modifications. RAT is a stand-alone structure that can be fully fabricated, pre-commissioned and installed without any interruption to existing platform operation.
KCI executed the design and developed a standardized low cost solution that can be applied across all the prospects both in UK and Dutch sectors of North Sea. The first RAT was installed successfully in the Dutch sector next to K15-FA-1 platform (2009-2011).
