DEEPBUOY – DEEPWATER LIFTING
We think differently
Ecosse Subsea Systems are the preferred subsea engineering partner for Aubin’s DeepBuoy Deepwater Lifting System
DeepBuoy is a patented pumpable flotation gel that can be used in water depths up to 3000m. The gel is incompressible and stable, with many potential applications including:
| Oil and gas: | Deepwater ROV construction Installation and recovery of large objects, e.g. manifolds, trees Decommissioning Recovery of lost components, vessels Riser buoyancy Deepwater salvage |
| Military: | Buoyancy for and recovery of submarines Aircraft salvage |

Features
- Transferrable “pumpable” buoyancy
- Capable of 3000m water depth
- Low density (550 Kgs/M3) Liquid
- Capable of lifting and lowering large heavy structures from seabed to near surface
Benefits
- Precise and safe way to place, move and recover structures from depth
- Can be used well beyond normal diving depths
- Extends depth and lift capabilities of cranes, winches and drill strings
- Increases capabilities of existing construction vessels
- Finely controlled lift is very safe for moving or adjusting objects such as pipelines that are in live production
- Use of conventional ROV means that job can be completed with other ROV activities on a campaign, no special heavy lift mobilisation required.
- Limitless applications
Problems solved by the technology
- Provides safe means of lifting, moving and placing structures on or off seabed (particularly subsea construction, decommissioning, FPSO riser support installation)
- Huge pressure at great depths means divers/airbags not suitable for work
- Extends lifting capacity of cranes, can lift from 2T to 2000T
