UG: Assisted Lifting of Pipelines

Availability: On Request

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).
