APPLICATIONS
■ Hydrate, paraffin, and
asphaltene remediation
■ Well stimulation and acidizing
■ Scale squeezes
■ Well kill
■ Pipeline and umbilical flushes
■ Plug and abandonment (P&A)
■ Commissioning and decommissioning
ADVANTAGES
■ Safer operations and reduced risk
■ Field-proven technology
■ Environmental acceptability
■ Cost effectiveness
■ ROV operability
■ Fast mobilization
■ Emergency disconnect function
■ Ability for one insert to cover entire field
■ Architecture flexibility on
connection points
The OneSubsea portfolio of MARS* multiple
application reinjection systems includes subsea
modular injection systems, which can be
deployed from a vessel of opportunity for subsea
fluid injection.
The systems offer significant benefits
to operators with simpler and safer
operations through
■ independent injection skid optimized
for deployment and ROV operations
■ pressure-balanced weak link (PBWL) that
enables ESD by hydraulic actuation (active)
or by line pull
■ PBWL gimbal system that connects to the
PBWL to accommodate up to 40° riser angle
shift from vertical
■ ROV flying jumper that requires no lifting
or load handling close to critical subsea
architecture elements
■ fail-safe-close barriers activated by ROV
or passively in the event of disconnect
■ specially designed mudmat for deepwater
low-strength soils
■ skirt design that ensures increased lateral
resistance is available
■ moonpool deployment to reduce heave-
induced motions on coiled tubing
■ conventional injector head that eliminates
plastic cycling during injection operation
■ CoilScan* engineered pipe management
service and universal tubing integrity
monitoring system for monitoring coil tubing
mechanical properties
■ openwater CT fatigue monitoring system.
