UG: Assisted Lifting of Pipelines

Availability: ,

The Assisted Lifting of Pipelines is an innovative lifting solution with UG MBUs and IBUs from our Seaflex product line. 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).


Flat-packed for efficient and cost-effective transport and stowage.

Weighing less than 1% of its uplift capacity: eg 5t unit less than 50kg.

Quick to rig, and easy to vent for ultra-safe recovery.

Immediately available for rental or purchase from the world’s largest stock of such equipment.

ISO 9001-2009 Quality Management Standard compliant
