Wire Rope Online Inspection System For Offshore Drilling Rig

Wire Rope Online Inspection System For Offshore Drilling Rig

1. The safe operation of wire rope is always in a completely controlled monitoring state.
2. The inspection is completed during production, thus leading the two processes of production and inspection combined into one, effectively improving the utilization rate of equipment.
3. It can reduce energy consumption of the equipment used for wire rope detection, save energy and reduce consumption significantly;
4. It can scientifically extend the service life of wire rope and reduce the cost of wire rope.

Outstanding safety, economic, environmental protection and management benefits

ComparisonTraditional manual inspectionTCK.W innovative technology
1. Safety pain points

Manual testing speed is 0.3m/s, which is low efficient, not reliable.

24 hours X365 days online real-time automatic monitoring, Raise wire rope and coiled tubing safety to the highest level.

2.Costdecreasing and benefit increasing

Rope inspections are executed in two shiftsper day, each inspection consumes 0.5 hour in each shift, 1 hour per day. Inspection will cost 330 hours in 330working days each year.Complete inspection while production, save testing time 1h per day, increase working time per rig per year > 300h.

3.Dual carbon target

Sacrificing cost to ensure safety causes serious waste of wire rope and coiled tubing.Full life cycle safety monitoring, scientific reduction of use costs. To provide a technical enabler for the circular economy and achieving dual- carbon targets.
4. Human cost reduction611 Kwh energy are consumed each day for manual inspection, and totally 201,630 kWh each year.Save annual energy consumption for inspection 201630Kwh, reduce carbon dioxide emissions 201,025Kg.
5. Human costTwo persons are needed for drilling rope inspection each day, and it takes 2 hours for it. Total inspection time is 660 hours.Machine intelligent inspection replace manual testing
6. Scientific managementRope inspection records are scattered, with poor retrieval.Test big data assurance, the results can be traced. Accurately assess the safety status and life cycle of wire ropes and coiled tubing.
