Distinct Medley fig
When Aker Solutions acquired Managed Pressure Operations in 2013, it became a provider of next generation continuous circulation and managed pressure drilling (MPD) systems, which has become a critical component to the drilling process going into the future. MPD systems have proven to be reliable, enabling maximum up time and significant cost savings and has been labeled of strategic importance for pre-salt drilling by Brazilian operator Petrobras, which uses MPD systems developed by Weatherford, which was the company that first introduced large scale use of the system to the industry. The MPD system being introduced by Aker/MPO is fully automated and simple to operate, needing few people to run the equipment.

Deepwater Riser Technology

June 24, 2014

bundled hybrid riser
Un-coupled riser systems are increasingly being used in deepwater and ultra-deepwater field developments, where harsh environments predominate. Hybrid Riser Towers (HRTs) are recognized to have significant benefits for deepwater riser applications in terms of flow assurance, thermal performance and robustness of layout. This latter issue is especially significant when a large number of risers are considered. An HRT provides the required flexibility by avoiding a crowded layout and allowing a progressive deployment. The concept is applicable to deepwater and ultra-deepwater, and to spread-moored and turret-moored FPSO installations. The Single Hybrid Risers (SHR) in its Single or Pipe-in-Pipe versions…
