ABERDEENSHIRE, UK – i-Tech 7, Subsea 7’s Life of Field business unit, has completed a subsea decommissioning and abandonment project for LLOG Exploration Co. in the Gulf of Mexico, using its smart skid technology.
LLOG was seeking better ways to flush three flowlines and two umbilicals as part of the work scope to abandon the G1 115 platform. Instead of using the conventional method of coil tubing, i-Tech 7 developed a subsea high-flow flushing skid solution to flush the flowlines.
The company used its hydrate remediation skid (HRS) solution to remove blockages within the tubing of two umbilicals. The system was said to deliver cost savings by facilitating the decommissioning of the umbilicals in place, rather than full recovery and disposal onshore.
The HRS incorporates smart, real-time software to efficiently remediate and prevent build-up of hydrate in subsea production facilities.
It is suitable for deepwater operations up to 3,000 m (9,842 ft), and is designed to interface with both work and heavy-duty work class ROVs.
