P-55 and P-57 Project
As of December 31, 2006 there was a project to develop production at Module 3 in the Roncador field (P-55) and Phase 2 of Jubarte field (P-57). A Deepwater charter LLC and a Deepblue Charter LLC were responsible for jointly contracting four SPCs to build the UEP: one for the P-55 hull, another for the P-57 hull, as well as two other for Generation and Compression Modules for both UEPs. In 2007, Petrobras decided not to share the project and to develop it by itself.
