... to allow the use of flexible pipes that are resistant to contaminants such as CO2 and H2S, new CRA materials to be applied to rigid flowlines and low-cost riser configurations, have been pursued by Petrobras in order to enable the implementation of ultra-deep water projects. subsea system petrobras...

... Abstract Large diameter UDW flexible pipes usually require lazy-wave configuration to withstand operational fatigue life. In a response to the current uncertain oil/gas price, the opportunity to design and deploy Free Hanging Catenary risers has been identified as the means to significantly...

... of a Venturi for the improvement of system stability, increase in production and recovery. A Venturi is coupled to the pipeline-riser system upstream of the choke valve before the topside test separator for severe slug mitigation. Experiments were carried out in a 2″ pipeline-riser system which comprises...

... Abstract A novel riser concept is being investigated. This is the branched riser system (BRS) with different configuration types including the branched steel catenary riser (BSCR), the branched steel lazy wave riser (BSLWR) and the branched lazy wave hybrid riser (BLWHR). As part of the design...

... Abstract The novel ‘Gimbal Joint Riser’ (GJR) device is an invention that allows for a free-hanging riser catenary configuration by providing the functionality of adding a ‘hinge’ or articulation in midway of the riser column. Such mid-length articulation allows that dynamic bending...

... Abstract This paper highlights the challenges to drilling risers and running equipment for offshore drilling operations from dynamically positioned mobile offshore drilling units (MODUs) in extreme water depths. Whereas nearly all exploratory drilling has occurred in water depths shallower than...

Abstract This paper presents the technical solutions assessment and details of the first implementation of the pre-laying procedure of flexible lazy wave risers, including buoyancy modules, before FPU arrival, on a Pre-Salt scenario. Flexible risers are easily handled due to the small bending...

... Abstract So far, off the coast of Brazil, steel catenary risers (SCRs) are only used in the subsea gathering system when connected to a semi-submersible FPU (Floating Production Unit) or a Buoy Supported Risers system (BSR). This paper presents a technical feasibility study for the use of SCRs...
