Assisted Lifting of Pipelines

Seaflex Use of Buoyancy for Assisted Lifting of Pipelines Application Note

Assisted Lifting of Pipelines

Innovative lifting solutions with Seaflex MBUs and IBUs

Whilst most commonly used for the laying of pipelines, whether being pulled from shore or being deployed from a laybarge’s stinger, Seaflex buoyancy bags are also commonly used for the lifting of pipelines from the seabed in conjunction with derricks or winches for tasks such as Above Water Tie Ins (AWTIs) or for repair or retrieval operations.

In normal circumstances, we would recommend the use of our parachute-style Air Lifting Bags (ALBs) for general lifting exercises such as diving operations and salvage projects. However, there are certain scenarios where an enclosed bag – be it one of our Mono Buoyancy Units (MBUs) or Inflatable Buoyancy Units (IBUs) - is the perfect solution for such lifting of pipelines. This application note will identify and explain the advantages of the use of Seaflex enclosed buoyancy bags within some of these scenarios. Download the full details from the pdf on the left or send us an enquiry for further information.
