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 heaveinduced 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.
