Containerized Air Decompression Chamber with Control Panel (TPI Approved)
J. K. Subsea Engineering Pvt. Ltd. is a trusted air decompression chamber manufacturer and supplier, building the Containerized Air Decompression Chamber with Chamber Control Panel, Model No. JK-ADC-CP-C, for commercial diving operations that need a fully equipped, third party inspected decompression system ready to deploy offshore. Housed inside a DNV 2.7-1 certified offshore container, this TPI approved decompression chamber combines a 60 inch twin lock chamber, a dedicated chamber control panel, and a full set of life support equipment inside the chamber itself, giving diving contractors a complete, inspected system rather than separate components sourced from different suppliers.
What is a Containerized Air Decompression Chamber with TPI Approved Control Panel?
A containerized air decompression chamber is a complete decompression and recompression system built inside a standard offshore container, giving diving contractors a chamber, control panel, and supporting life support equipment that can be transported, lifted, and connected on site without additional fabrication. This unit houses a 60 inch (1500 mm) twin lock decompression chamber built to ASME Section VIII Division 1 and ASME PVHO-1 (2022) standards, with the design compliant with IMCA D018 and IMCA D023 guidelines. Being TPI approved, the chamber shell is built to approved drawings and carries a TPI stamped nameplate, meaning an independent third party inspection agency has verified the fabrication and testing rather than relying on the manufacturer’s own sign off. That independent verification is what many offshore operators and diving contractors require before a recompression chamber is accepted onto a project.
Key Features of the TPI Approved Air Decompression Chamber
Our TPI approved containerized decompression chamber is built to support a full offshore decompression operation from one self contained unit.
- TPI Approved Chamber Shell: 60 inch twin lock chamber shell built to ASME Sec VIII Div. 1 and PVHO-1 (2022), constructed to approved drawings and carrying a TPI stamped nameplate.
- DNV 2.7-1 Offshore Container: ISO or DNV standard offshore container fitted with DNV 2.7-1 certified lifting pad eyes for safe offshore handling.
- Dedicated Chamber Control Panel: Positioned at operator eye level, with entry lock, main lock, and therapeutic depth gauges, panel mounted oxygen and carbon dioxide analysers, and dual scale supply gauges.
- Battery Backup for Up to 8 Hours: Control panel stays powered during a mains failure, keeping monitoring and communication running without interruption.
- Air Conditioning and Power Backup: Two 2 TR split AC units and a UPS backed power system for reliable operation in high ambient temperatures.
- Onboard Breathing Air and Oxygen Gas Bank: 2 breathing air cylinders and 2 oxygen cylinders provided inside the container.
- IMCA Compliant Design: Chamber system designed compliant with IMCA D018 for diving plant examination and testing, and IMCA D023 for surface oriented air diving system design.
- Twin Lock Decompression 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 Chamber Monitoring System: Real time temperature and relative humidity monitoring with DVR storage of internal chamber data.
- Full Set of Internal Life Support Equipment: CO2 scrubber, hyperbaric light, hyperbaric camera, built in breathing system, hyperbaric fire extinguisher, fire retardant mattresses, talk back speaker, caisson gauge, and a hygrometer with thermometer, all fitted inside the chamber.
- Fire Safety System with Onboard Fire Tank: Fire line, portable extinguishers, and a dedicated 200 litre high pressure fire tank inside the container for emergency response.
What's Inside the Air Decompression Chamber
Since the air decompression chamber is used as a life saving system in offshore fields, it is fitted with a set of dedicated devices that support the diver or occupant throughout the decompression or treatment process.
- CO2 Scrubber (JK-CO2S-ALPHA): Draws CO2 from breathing air through a soda lime absorbent, supporting proper breathing for up to 4 hours.
- Hyperbaric Camera (Model No. JK-HYC-300M)
Used for monitoring movement and activity inside the chamber, with the live feed shown on the chamber control panel. Fitted inside both the entry lock and the main lock.
- Hyperbaric Fire Extinguisher (Model No. JK-HYF-6.7L)
A fire suppression device specifically designed for use inside pressurised environments such as hyperbaric and decompression chambers.
- Caisson Gauge (6 inch dial, 0-7 MSW)
Indicates the internal depth or internal pressure present inside the chamber at any given time.
- Hyperbaric Light (Model No. JK-HYL-300M)
Provides lighting inside the chamber during pressurisation, fitted inside both the entry lock and the main lock so visibility is maintained throughout the operation.
- Built In Breathing System, BIBS (Amron Model No. 350M)
Lets the diver inside the chamber breathe oxygen supplied directly from the oxygen line, giving a dedicated breathing source separate from the main chamber atmosphere.
- Talk Back Operator (Model No. JK-TBS)
An internal loudspeaker fitted inside the main lock, allowing occupants to hear voice communication coming from the chamber control panel.
- Hygrometer with Thermometer
Measures and displays the relative humidity and temperature inside the chamber, supporting continuous environmental monitoring.
Additional Features and Provision for the Decompression Chamber Container
- Air Conditioning System: Two 2 TR split air conditioning units maintain a controlled, comfortable internal temperature inside the container, supporting reliable operation in high ambient temperature regions.
- Fire Safety System: A fire line and portable fire extinguishers cover fire emergencies inside the container, with additional coverage for all three viewports and a dedicated 200 litre high pressure fire tank for emergency use.
- Interior Enhancements: Decorative lighting and ventilation fans improve illumination, airflow, and overall interior comfort.
- Supervisor Seating Arrangement: A 3 person sofa is fitted inside the container, giving the supervisor a comfortable rest space during extended operations.
- Environmental Monitoring System: A wall mounted clock integrated with a temperature and relative humidity indicator gives continuous monitoring of conditions inside the container.
- Onboard Gas Bank: 2 breathing air cylinders and 2 oxygen cylinders are provided inside the container as onboard gas supply.
Applications of the Containerized Decompression Chamber
Our TPI approved ADC container supports decompression and hyperbaric 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 for Divers: Twin lock design allows a medical attendant to enter through the entry lock while the diver remains under treatment pressure in the main lock.
Marine Construction and Subsea Projects: Gives contractors a mobile, TPI approved decompression system for offshore construction diving.
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.
Offshore Oil and Gas Diving Support: Keeps commercial divers supported with an inspected decompression chamber during platform inspection and maintenance work.
Projects Requiring Independent Inspection Certification: Suited to clients or regulatory bodies that require third party verification rather than manufacturer self certification.
