Frequently Asked Questions

20Ft Containerized Decompression Chamber

What is a containerized decompression chamber?

A containerized decompression chamber is a complete hyperbaric decompression system installed inside a transportable container, typically a 20ft offshore or ISO container. It allows commercial diving teams to provide controlled decompression and emergency treatment for divers directly on site or onboard vessels without requiring a fixed hyperbaric facility.

---

What is a twin-lock decompression chamber?

A twin-lock decompression chamber consists of two connected compartments, usually referred to as the main lock and entry lock. This configuration allows divers to enter or exit the chamber without affecting the pressure inside the main compartment, enabling continuous treatment and operational flexibility during decompression procedures.

---

Why are containerized decompression chambers used in commercial diving?

Containerised chambers provide a mobile and self-contained decompression facility for offshore and inshore diving operations. They are widely used because they:

• Allow rapid mobilisation to vessels or project sites
• Provide controlled decompression for surface-supplied diving
• Support emergency recompression treatment if required
• Integrate with dive control and life support systems
• Meet industry safety and compliance requirements

---

What diving operations require a decompression chamber?

Decompression chambers are commonly used in:

• Offshore commercial diving operations

• Harbour and marine civil engineering projects

• Salvage and underwater recovery operations

• Offshore wind farm installation and maintenance

• Oil and gas subsea construction

• Research and inspection diving campaigns

Many diving standards and project specifications require a DDC to be available whenever surface-supplied diving operations are conducted.

---

What standards apply to commercial diving decompression chambers?

Commercial diving decompression chambers are typically designed and operated in accordance with recognised industry standards such as:

• IMCA D018 – Testing and certification of diving plant and equipment

• IMCA D023 – Design for containerised diving systems

• Classification society approvals such as Bureau Veritas or similar

• National diving regulations depending on operating region

Compliance with these standards ensures the system meets recognised safety, testing, and operational requirements.

---

What is included in a containerized decompression chamber system?

A typical 20ft containerised decompression chamber package includes:

• Twin-lock decompression chamber

• Diver control panel (air or mixed gas)

• Communications system for diver and chamber operator

• Oxygen and carbon dioxide monitoring

• Life support monitoring equipment

• Air storage cylinders or gas supply integration

• Video monitoring and system displays

• UPS power backup systems

These systems are integrated within the container to create a fully operational decompression facility.

---

What size chamber is typically used in a 20ft container system?

Many commercial containerised decompression chambers use a 1500 mm (60 inch) diameter twin-lock chamber, which provides sufficient internal space for diver treatment while maintaining compatibility with container transport dimensions.

---

Can containerized decompression chambers be customised?

Yes. Containerised decompression chambers can be configured to suit specific operational requirements. Customisation options can include:

• Air or mixed-gas diver control panels

• Additional gas storage banks

• Integrated compressors or gas reclaim systems

• CCTV and monitoring upgrades

• Environmental control and HVAC systems

• Alternative container specifications such as DNV offshore containers

---

What industries use containerized decompression chambers?

Containerised decompression chambers are used across multiple subsea and marine industries including:

• Commercial diving contractors

• Offshore energy and oil & gas operations

• Offshore wind installation

• Marine civil engineering companies

• Salvage and subsea recovery teams

• Government and research diving programmes

---

How is a containerized decompression chamber transported?

These systems are designed for standard transport and offshore lifting, typically using:

• ISO container handling

• Offshore cranes via certified lifting points

• Vessel deck mobilisation

• Road transport using flatbed trailers

This portability is one of the main advantages of containerised decompression systems.
