Green Turtle
Oil Well abandonment operations have so far been either highly expensive operations or have caused a major safety risk for the involved personnel. Consequently, a new cutting system needed to be designed that had to be fully remotely operated and optimally have a self jetting functionality. With Green Turtle these requirements are more than met.
Green Turtle - Oil Well Abandonment
- Cuts conductor down to 5 meters (15 ft) below mud line.
- Totally remotely controlled.
- Self jetting.
- Environmentally friendly.
- Cutting operation is supported and monitored by using state-of the art computer simulation software.
- Real time visualization
Product Overview
Green Turtle is a remotely operated cutting tool developed to be lowered down onto the conductors from a vessel. Once in position by diver/ROV assist the Green Turtle will guide itself down a conductor, jet down to target depth, cut the conductor, then retrieve the cut piece back to the surface. Green Turtle consists of four diamond blades that rotate and cut towards the inner center of the conductor. The blades are mounted on a sleeving ring that is powered by two electrical motors.
SAFE & EFFICIENT OPERATION
Green Turtle is very safe to operate, since no divers need to be working near the cutting area. Having the desired self jetting functionality, the jetting and cutting process will be a continuous operation requiring only one deployment. By monitoring the cutting operation and using real time visualization, maximum effective and safety will be achieved.
ENVIRONMENTALLY FRIENDLY
As the whole operation is much more efficient that with manual methods by divers, CO2 emissions are minimized as more conductors are cut per operating hour.
