PUMPABLE BUOYANCY

Pumpable buoyancy to provide controlled, adjustable lift up to 3,000 under water

LiquiBuoy and DeepBuoy offer precise and controlled lift compared to commonly used air bags, bringing an important safety benefit over the notoriously dangerous and difficult to control air bags. Unlike air bags, our liquid buoyancy is non-compressible so has the same lift regardless of depth in the water column, offering safe, controlled lifts.

How this technology works:

Aubin’s patented pumpable buoyancy products can be pumped to fill objects of simple or irregular shape, unlike syntactic foam buoyancy. The low-density, incompressible, liquid materials offer buoyancy consistent with depth, unlike other products which have reduced buoyancy as they go deeper.

The buoyant liquid can be poured or pumped to fill any void and can generate close to a pound-for-pound lift with an entirely scalable performance able to lift any mass up to 3,00 metres depth.

Challenges Faced

Developing pumpabale buoyancy products which can be used in Ultra-deepwater lifting in complicated subsea settings.

How Pumpable Buoyancy can help

Three pumpable buoyancy products, DeepFloat, LiquiBuoy and DeepBuoy. When pumped into an annulus, it reduces an object’s mass in water, making it easier for cranes, divers and ROVs to lift.

Pumpable buoyancy is the solution for:

Irregular shaped objects which prohibit use of syntactic buoyancy.
Applications where there are concerns over the safety of airbags.
Lifting operations at depths of 3000m without loss of buoyancy.
More cost efficient lifting operation compared to using offshore crane vessels

Unlike air bags, our liquid buoyancy is non-compressible so has the same lift regardless of depth in the water column, offering safe, controlled lifts
