The oil industry has faced growing demand for subsea facilities to enable the development of ultra deepwater oil fields. The use of manifold is an alternative widely considered in subsea arrangements. In order to apply this alternative, it is necessary to follow a chain of project that demands special care since its manufacture, installation, commissioning, productive life and possible demobilization, being able to culminate with the removal of equipment from the location. These equipments, sometimes weighing a few hundred tons, require special attention during planning the installation. Thus, this paper proposes to present the challenges faced in the planning and installation of subsea equipments in deepwater, the evolution of the manifold installation techniques at Petrobras, as well as present the main installation methods currently used in Pre-Salt fields and new techniques in development for the installation of large subsea equipments.
