Containerized Air Decompression Chamber with Diving Air Panel (CLASS)
J. K. Subsea Engineering Pvt. Ltd. is a trusted Air Decompression Chamber manufacturer, building the Containerized Air Decompression Chamber with Diving Air Panel, Model No. JK-ADC-AP-CLASS, for commercial diving operations that need a class approved hyperbaric system ready to deploy offshore. Housed inside a DNV certified offshore container, this class approved decompression chamber combines a 60 inch twin-lock chamber, a full chamber control panel, and a configurable diving air panel in one transportable unit, so diving contractors get a complete surface decompression system without sourcing components separately.
What is a Containerized Air Decompression Chamber?
A Containerized Air Decompression Chamber is a complete decompression system built inside a standard offshore container, giving diving contractors a chamber, control panel, and diving air panel that can be lifted, transported, and connected on site without a separate build-out. This unit houses a 60 inch (1500 mm) twin-lock decompression chamber built to ASME PVHO-1 and ASME Section VIII standards, along with a chamber control panel and a diving air panel designed to IMCA D023 and certified to IMCA D018. Being class approved, the chamber shell comes with class witnessed drawings and a classed stamped nameplate, so it can be verified and accepted for offshore diving operations without additional third-party inspection delays. This is what separates a containerized ADC from a standalone chamber skid, everything from breathing air supply to diver monitoring is already integrated and tested before it reaches site.
Key Features of Containerized Air Decompression Chamber with Diving Air Panel
Our containerized decompression chamber, also used as a class approved diving chamber container, is built to support a full offshore surface decompression operation from one self-contained unit.

- IMCA Compliant Design: Chamber and diving air panel designed to IMCA D023 for surface oriented air diving systems, and certified to IMCA D018 for diving plant examination and testing.
- Twin-Lock Chamber with Entry and Main Locks:Entry lock rated for 2 persons and main lock rated for 4 persons, with a stainless steel medical lock included.
- High Definition Monitoring System:Real time temperature and relative humidity monitoring with DVR storage of internal chamber data.
- Configurable Diving Air Panel: Available in 2 diver, 3 diver and 4 diver configurations to match project requirements, complete with high pressure and low pressure lines, downstream gauge, and pneumo supply gauge.
- DP Status Alarm: Visual and audible alert if the dive support vessel’s DP system faults or loses positioning.
- Fire Safety and Supervisor Comfort:Fire line with portable extinguishers, supervisor breathing apparatus set, and a 3 person seating arrangement for extended operations.
Applications of Containerized Air Decompression Chamber with Diving Air Panel
Our class approved ADC container supports surface decompression treatment across a range of commercial diving and offshore projects.
Surface Supplied Diving Operations: Provides decompression and treatment capability for divers working on offshore platforms, pipelines and subsea infrastructure.
Recompression Treatment: Twin-lock design allows medical attendants to enter through the entry lock while the diver remains under treatment pressure in the main lock.
Marine Construction and Salvage Work: A mobile, class approved decompression system for contractors running diving spreads on construction or salvage vessels.
Dive Support Vessel Operations: A self-contained chamber and control panel package that can be craned onto a DSV and connected to power without additional fabrication.
Multi-Diver Commercial Diving Spreads: The configurable 2, 3 or 4 diver air panel matches the chamber to the size of the diving team on any given project.
Offshore Oil and Gas Projects: Keeps commercial divers supported with certified decompression capability during platform inspection and maintenance work.
