Cleaner and more efficient heavy lifting for subsea operations

Inovatum Lifting has designed the world’s first water-based hydraulic shackle. They can replace traditional, oil-based hydraulic shackles for more environment-friendly heavy lifting in offshore operations.

Hydraulic shackles are used for lifting large and small structures in subsea operations. They are preferred to manual shackles when operating in confined spaces or difficult conditions where personnel cannot easily fasten or release a shackle themselves.

Traditional hydraulic shackles, however, are large, oil-based devices, which require a great deal of manpower to operate. There is also the risk of small oil spills.

To simplify subsea lifting and make offshore operation less resource-intensive, operators need access to new technologies.

Water-based hydraulic shackle

Inovatum Lifting has developed the world’s first water-based hydraulic shackle, the patented INOshackle™. It is powered only by water or air, eliminating the risk for oil spills.

The INOshackle allows as many shackles as needed to be connected at the same stab point, meaning multiple shackles can be fastened and released instantly and simultaneously.

In its standard configuration, the INOshackle is designed for lifting and positioning structures and equipment of between 25 and 150 metric tons. Custom designs, however, are also available, making possible lifts of between 9 and 6-7 000 metric tons, or more.

The INOshackle is designed and tested according to DNV GL’s classification for offshore and platform lifting applications, DNVGL-ST-0378. It available both for purchase and rental.

Concrete benefits

The INOshackle can reduce the time spent on lifting operations with several hours. It thereby reduces greenhouse gas emissions from offshore vessels, as well as manual labour hours at sea.

The INOshackle is, moreover, lightweight and small in size, enabling more nimble operations and improving safety for offshore personnel.

Finally, because the INOshackle does not employ hydraulic oils, there is no risk of oil spills or contamination.

Market potential

The INOshackle is suitable for a multitude of offshore operations, from the oil and gas sector to wind and tidal power and also aquaculture. Any sector that requires heavy lifting at sea can benefit from the INOshackle.

Inovatum Lifting operates in Asia, Australia, Brazil and Europe. The company was founded in 2013. In future, it is looking to expand the uses for its patented water-hydraulic technology beyond subsea lifting.
