Ambient Lifter

EIP’s innovative Ambient Lifter allows accurate and safe subsea lifting – either using low cost vessels with no requirement for heave compensation, or using ROVs/AUVs.

Ambient lifter can be used in a variety of industries including Oil & Gas, offshore wind and wave power, leading to significant project cost savings during construction, operations & maintenance and decommissioning.

The system can be used to lift, lower or hover any subsea object, by controlling buoyancy and ballast in low pressure pipes. It is an innovative and new way of lifting subsea assets faster and more cost effectively than ever before, bringing new confidence to subsea lifting challenges.

The technology drives significant cost savings for subsea installation – a small towing vessel can be used to float the structure to site and install it.

For decommissioning applications, the EIP Ambient Lifter can be used to float items such as jacket sections from decom zone to shore behind small towing vessels, or lift decom debris in the 500m zone into subsea baskets which can be recovered by anchor handler vessels.

Ambient Lifter for decommissioning and debris clearance
This animation shows how our Ambient Lifter can be utilised for decommissioning and subsea debris clearance applications.

The Ambient Lifter makes the entire system (including the item to be lifted) neutrally buoyant which allows the ROV to manoeuvre much larger masses than a conventional work class ROV.

Benefits include:

  • Accurate control
  • Lift capability controlled by ROV or surface pump
  • Buoyant force independent of depth (unlike air bags)
  • Incompressible
  • Environmentally safe using only air and water

Applications include:

  • Subsea structure installation
  • Foundations (where heavy ballast can be used)
  • Pipeline installation
  • Decommissioning
  • Salvage
  • Air bag replacement
  • Subsea transportation
