Subsea lifting solution

Page last modified

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.

Pro/con

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
Ambient Lifter is yet to be commercially deployed.

Specification

Cost The EIP patented Ambient Lifter has been designed to provide a cost-effective subsea lifting solution which is not affected by surface weather conditions.
Modularity Engineered as a modular unit the Ambient Lifter is configurable to handle a range of weights – anything from 10te to 2400te.
Installation The Ambient Lifter uses a novel methodology and can be launched from a low-cost anchor handler vessel or towed to site using a tug, negating the requirement for an expensive crane or heavy lift vessel.
Areas of Application Subsea structure installation | Foundations (where heavy ballast can be used) | Pipeline installation | Decommissioning | Salvage | Installation and recovery of Christmas trees | Air bag replacement | Subsea transportation
Operating Conditions Ambient can be operated by the ROV subsea or can be controlled on the surface by the vessel
