Saturation Diving Systems

Overview of Saturation Diving Equipment

Unique Group designs and integrates saturation diving equipment for offshore vessels, dive support ships, and land-based training centres. Each system combines hyperbaric chambers, transfer-under-pressure (TUP) modules, diving bells, and life-support control units to ensure diver safety and comfort during long-duration missions.

Our equipment are engineered to meet international commercial-diving standards, providing complete control over pressure, temperature, and gas composition.

Complete Range of Saturation Diving Systems

We offer a comprehensive portfolio of DNV-certified and modular saturation diving solutions, including:

• Single-bell and twin-bell diving support vessels (DSVs)

• Hyperbaric reception facilities (HRF) for safe diver transfer and treatment

• Modular containerized SAT systems for flexible offshore deployment

• Custom-built systems tailored to project requirements and operational capacities

Our solutions are trusted by offshore energy operators, subsea contractors, and rescue teams worldwide.

Built for Safety, Compliance, and Performance

All Unique Group SAT systems are manufactured to the highest international standards (DNV, IMCA, ABS), ensuring:

• Unmatched diver safety in extreme subsea environments

• Proven reliability and durability through rigorous testing and quality control

• Operational flexibility with modular designs that can be scaled or upgraded as required

• Enhanced project efficiency, enabling divers to work in extended shifts while reducing downtime

Key Features and Technology

What makes modern saturation systems safer and more efficient?

• Integrated Communications: Real-time voice and data exchange between divers and topside teams.

• Advanced Gas-Management Systems: Automated regulation of helium-oxygen mixtures for extended depth operations.

• Environmental Control: Precision management of temperature, humidity, and CO₂ levels inside the chambers.

• System Redundancy: Dual power, life-support, and monitoring circuits for continuous safety.

• Remote Monitoring: Digital dashboards allowing operators to track chamber status and life-support parameters.

Maintenance and Reliability

How is saturation diving equipment maintained?

Preventive maintenance and calibration ensure long-term reliability:

• Perform routine pressure tests on chambers, valves, and bell components.

• Calibrate sensors and gas analysers at defined intervals.

• Conduct electrical and communication checks before each mobilisation.

• Keep service logs and certification records for audit and compliance.

Unique Group provides inspection, recertification, and spare-parts support through regional service hubs to maintain 24/7 operational readiness.

Applications of Saturation Diving Systems

Where are saturation systems used?

• Oil & Gas Operations – Pipeline installation, platform maintenance, and deep-water inspections.

• Offshore Construction – Structural welding, subsea assembly, and repair tasks.

• Decommissioning Projects – Removal and dismantling of subsea infrastructure.

• Training Centres – Controlled-environment diver training and certification.

Frequently Asked Questions

What type of chamber should be used for commercial diving operations?

For commercial diving operations, a saturation diving chamber system is typically used. This system allows divers to live and work at pressure for extended periods, minimizing the frequency of decompression. The chamber is equipped with advanced communication systems to maintain constant contact between the divers and surface support teams, ensuring safety and operational efficiency.
