... Abstract The first Petrobras Hybrid Riser was installed in Campos Basin and is part of the Roncador P-52 oil export system. This system, which connects the SS platform P-52 (1800m water depth) to the fixed unit PRA-1 (100m water depth), is in operation since November 2007 comprises an 18...

... Abstract The increased number of hybrid riser systems, either installed or planned, in deepwater regions across the world has driven a corresponding growth in the use of dynamic riser base steel jumper jumpers to connect these towers to subsea pipelines. The experience of the authors across...

... ABSTRACT With the successful deployment of the five Cascade & Chinook free standing hybrid risers (FSHRs) in the Gulf of Mexico at a water depth of 8,250 ft in year 2010, hybrid riser technology is adopted for deepwater development worldwide. It is basically a combination of steel...

... Abstract Located in 8,200 feet water depth, the Cascade & Chinook subsea development risers are the deepest production risers in the world. These are also the first offset free-standing hybrid risers to be installed in the Gulf of Mexico, and the world's first use of hybrid risers...

... ABSTRACT As one of the field proven riser concepts, tower riser is a popular concept in particular for deepwater application in the West of Africa (WoA). This paper addresses on the design exercise of a deepwater tower riser in WoA. A brief presentation of deepwater hybrid riser history...

The mechanical and structural particulars of the proposed concept are outlined. The hydrodynamic and structural analyses of the TSBR performed with an efficient...

... Abstract Hybrid risers rely on axial tension, generated by a combination of aircan and distributed buoyancy, to control their static deflection and dynamic response. In deep water, the base tension required to achieve an acceptable response can be significant (70–1000Te). This tension must...
