Sometimes offshore drilling operations do not go to plan. One of our client’s experienced a broken marine drilling riser while drilling in 6000 feet of water. The riser parted at 3000 ft depth when a 42inch flange parted. The drill pipe spanning between the broken flanges was all that was preventing a catastrophic collapse of the drilling riser and a potential blowout.

ICON designed and built a large ROV deployable tool rated at approximately 400 tonnes to clamp around and latch onto the two riser flanges. The customer chartered a Russian Antonov aircraft to pickup the tool and tonnes of associated deployment equipment from Perth, the tool was ready to go 32 hours after the emergency call was received.
