Devin introduces dual compensating intervention tower
Devin International has introduced a modular motion-compensation tower that adapts to any type of vessel, platform, or rig that experiences motion during well intervention. It can move in two directions on its vertical axis.
The tower compensates for up to 3 m (10 ft) of rise-and-fall motion, sufficient for most jobs, but it can correct up to 6 m (20 ft) of vertical motion with the use of a double shive system, doubling capacity while maintaining a minimal footprint.
It can work over a moon pool or cantilever over the side or the rear of the vessel and is capable of working over a single well at full capacity or two wells with lesser capacity. Standing at 10.7 m (35 ft) tall, the tower is height-adjustable to accommodate the size of the tubing or wireline used and water depth at the site.
With a lift capacity of 68 metric tons (75 tons), the tower is limited only by the length and capacity of the wireline or coiled tubing and the intervention tools it supports.
It has not reached a field test benchmark it was unable to support, according to Devon.
