Because they're attached to the load via a single point of connection, they require significantly less rigging time than multi-attachment alternatives Its structural internal connecting strop between each end of the MBU makes it possible to lift through or moor onto Unique Group's MBUs – a capability which sets us apart from other products on the market.

The use of parachute-style Air Lifting Bags (ALBs) is recommended for general lifting activities such as diving operations and salvage projects under normal circumstances. However, in certain scenarios an enclosed bag is the perfect solution for lifting of pipelines. Such enclosed bags come in the form of Mono Buoyancy Units (MBUs) or Inflatable Buoyancy Units (IBUs).

]]> UG: Kraken for Pipe Laying https://www.uniquegroup.com/product/ug-kraken-for-pipe-laying/ Sat, 27 Aug 2022 15:39:38 +0000 https://www.uniquegroup.com/product/ug-kraken-for-pipe-laying/ Unique Group's Seaflex product line offers Kraken Bags for pipe laying. It provides temporary buoyancy for the launch and installation of shallow water pipes and supports lengthy sections during surface or bottom tows. From a beach launch, the equipment can take up the pipe weight in very shallow water and, with a suitable air supply, provide buoyancy at any depth. It's ideally suited to ultra-shallow applications such as the floating of pipeline through swamps, where its low profile ensures minimum draft throughout the operation.

]]> Made of the heaviest weight PVC coated polyester fabric tube with high frequency (HF) welded seams and mechanically fitted penetrators with location loops spaced at 1.33m pitch along the crown of the unit.

The coated fabric tube is extremely strong and made by the world’s leading performance fabric manufacturers.

By venting air, the buoyancy can be removed by remote control from the surface.

In round numbers, 10kg of packed flexible buoyancy will produce 1000kg of lift when inflated. A ratio of 100:1.

It can be used on pipes, suited for ultra-shallow work, perfect for pulling and towing. Chafe problems can be reduced or eliminated by design of the attachments.

The buoyancy of each IBU can be controlled from the surface during and after operations allowing users to safely apply and remove the load at zero capacity, only activating the buoyancy at the moment it is required.
