Unique Group designs and integrates saturation diving equipment for offshore vessels, dive support vessels and land-based training centres. A saturation system combines hyperbaric chambers, transfer-under-pressure (TUP) modules, diving bells and life support control units, so divers can live and work at pressure during long-duration operations.
The systems are designed to control chamber pressure, temperature and gas composition throughout the dive.

Saturation Diving Systems in Our Range
Our saturation diving range includes:
- Single-bell and twin-bell modular DSV systems for diving support vessels
- Hyperbaric reception facilities (HRF) for diver transfer and treatment
- Modular containerised SAT systems for offshore deployment
- Custom-built systems configured to project and operational requirements
- Supporting equipment, including bell heaters, chiller heater systems, environmental control systems and gas transfer compressors
Standards and Compliance
Unique Group saturation diving systems are designed and manufactured to [insert the verified standards, e.g. DNV, IMCA or ABS].
Modular designs allow systems to be scaled or upgraded as operational requirements change.
Key Features
- Communications: voice and data links between divers in the chamber or bell and the topside team
- Gas management: regulation of helium-oxygen breathing mixtures for deep saturation operations
- Environmental control: management of temperature, humidity and COâ‚‚ levels inside the chambers
- System redundancy: backup power, life support and monitoring circuits
- Monitoring: displays that allow operators to track chamber status and life support parameters
How Is Saturation Diving Equipment Maintained?
Regular maintenance and calibration keep saturation systems ready for operation. Typical tasks include:
- Pressure testing chambers, valves and bell components
- Calibrating sensors and gas analysers at defined intervals
- Checking electrical and communication systems before each mobilisation
- Keeping service logs and certification records for audit and compliance
Unique Group provides inspection, recertification and spare parts support for saturation diving systems.
Where Are Saturation Diving Systems Used?
- Oil and gas: pipeline installation, platform maintenance and deepwater inspection
- Offshore construction: structural welding, subsea assembly and repair
- Decommissioning: removal and dismantling of subsea infrastructure
- Training centres: diver training in a controlled environment

Frequently Asked Questions
What type of chamber is used for saturation diving?
Saturation diving uses a saturation chamber system, where divers live under pressure for the duration of a project. Because they stay at pressure between shifts, they only need to decompress once, at the end of the saturation period. The system includes communications between the divers and the surface support team.
