QinetiQ Haslar Diving and Hyperbaric Test Centre
QinetiQGosport, Hampshire
QinetiQ’s Diving and Hyperbaric Test Centre at Haslar supports research, testing and evaluation of diving, submarine escape, life-support and other hyperbaric systems. The current facility page and linked sheet describe separate pressure chambers, tanks, breathing simulators, an environmental cabinet and a high-flow air rig. Published limits belong to each named system. Agree the exact equipment, configuration and test programme with QinetiQ.

Key facts
- Exact centre and test site
- The DHTC is operated by QinetiQ at Haslar Marine Technology Park, Gosport, Hampshire PO12 2AG, United Kingdom. The sheet’s Farnborough corporate enquiry imprint is separate from the Haslar test location.
- Published user and test scope
- The centre supports Ministry of Defence and commercial organisations. Published work includes diving and submarine escape/rescue systems, life support, decompression procedures and forensic investigation of diving/life-support equipment.
- Separate equipment envelopes
- The LSSL chamber rating is 100 bar / 1000 m, while breathing evaluation is stated to 60 bar / 600 m. HTU is rated to 150 bar / 1500 m. HFR’s 310 bar value is air-reservoir maximum working pressure. These are separate equipment claims.
- Published enquiry routes
- Use the Haslar listing’s +44 23 9233 5000 or QinetiQ’s contact form for a Test & Evaluation enquiry. The currently linked sheet also prints HaslarFacilities@QinetiQ.com, without email-delivery verification.
Testing capabilities
Life-support and breathing-system evaluation
The LSSL supports breathing performance/endurance evaluation, respiratory gas and apparatus monitoring, carbon-dioxide absorbent performance and simulated metabolic oxygen consumption. The published chamber and breathing-simulator limits are separate, and the test configuration requires agreement.
Diving acoustics and suit thermal evaluation
The Experimental Diving Tank can be fitted with anechoic panels for acoustic measurement and diving-helmet noise evaluation. The sheet describes NEMO thermal-manikin evaluation of wetsuit, drysuit and immersion-suit insulation. Fresh/salt filling and fresh-water temperature control do not establish identical salt-water temperature limits.
Environmental and orientation-dependent hydrostatic testing
The environmental cabinet supports functional performance following extreme-temperature storage. The HETT is an open fresh/salt-water tank at atmospheric pressure, with a rotating mannequin/breathing-simulator configuration for hydrostatic load in diver orientations. Cabinet, water and breathing-gas conditions remain separate.
Hyperbaric and submarine-escape profile evaluation
The HTU supports assessment of submarine escape systems/components and pressurised escape-profile replication. The current page also describes pressure cycling of submersible components and undersea/deep-diving equipment testing. Its published 150 bar / 1500 m rating does not establish every item or test configuration’s suitability.
Compressed-air component flow testing
The High Flow Rig supplies compressed air to components and measures flow characteristics/mass flow. Its three-cylinder reservoir is rated to 310 bar maximum working pressure. The sources do not publish a numerical mass-flow limit or guarantee that this reservoir rating is the component’s outlet pressure.
Diving and life-support forensic investigations
The current DHTC page and linked sheet describe rapid forensic investigation of diving and life-support equipment following serious incidents. No fixed turnaround time, report format or unrestricted forensic scope is published.
Equipment and published limits
| Specification | Published value | Conditions |
|---|---|---|
| Life Support Systems Laboratory | Chamber 100 bar / 1000 m, breathing evaluation 60 bar / 600 m | Single-compartment wet/dry chamber with optional water fill. Fresh water 2–40 °C. Breathing gas humidification/heating 32 °C ±4 °C. Chamber, breathing evaluation, water and gas conditions are distinct, without a combined guaranteed envelope. |
| Experimental Diving Tank | Open tank 3 × 3 × 3 m, underwater anechoic chamber 2 × 2 × 2 m | Fresh or salt water fill. Fresh-water control 2–40 °C. Helmet-noise and NEMO thermal-manikin suit evaluation are stated. The fresh-water temperature range is not assigned to salt water. |
| Environmental cabinet | Temperature −40 to 180 °C, relative humidity 10–98% | Separate cabinet published ranges, with instrumentation/service access and associated breathing-gas heating 32 °C ±4 °C. No simultaneous temperature/humidity envelope or specimen dimensions were verified. |
| Hydrostatic and Extreme Temperature Tank | Atmospheric-pressure open tank, salt water −2 °C to ambient | Fresh/salt-water tank with orientation-dependent hydrostatic loading and breathing simulator. Gas heating 32 °C ±4 °C is separate. No 100/150 bar pressure-chamber rating is transferred to HETT. |
| Hyperbaric Trials Unit | 150 bar / 1500 m, spherical compartments 3 m and 2 m diameter | Two-compartment hyperbaric system. Main access and interlock doors are 0.75 m diameter. Compartment diameters do not establish unrestricted specimen capacity. Exact configuration, access and profile require confirmation. |
| High Flow Rig air reservoir | Three 1609 litre cylinders, 310 bar maximum working pressure | Reservoir and component flow-test system with mass-flow measurement and a 2-inch nominal-bore maximum outlet. No numerical mass-flow capacity or component outlet-pressure guarantee is inferred. |
Access and contact
Contact the Haslar site on +44 23 9233 5000 or use QinetiQ’s official form with Test & Evaluation as the area of interest. The linked DHTC sheet also publishes HaslarFacilities@QinetiQ.com and a separate Farnborough corporate phone +44 1252 392000. Specify the Haslar centre and agree equipment, item/configuration, pressure/depth profile, medium, temperature, gas, monitoring and report requirements. No booking or email delivery was verified.

What to confirm with the facility
- Each published limit belongs to its named apparatus. LSSL’s chamber and breathing-evaluation ratings differ. EDT fresh-water, HETT salt-water, cabinet and breathing-gas temperatures are separate. HFR’s 310 bar is a reservoir rating. Confirm the complete requested test configuration and any combined conditions.
- QinetiQ describes testing against defined programme standards and support for submarine-escape standards. The checked sources do not identify an exact current accredited method scope or named edition, so no accreditation or unrestricted standards compliance is inferred. The linked sheet’s 2021 copyright/reference and January 2026 PDF timestamps are separate records.
- Provide item dimensions and mass, pressure/depth and cycling profiles, water/gas and temperature conditions, interfaces, monitoring, safety constraints, report requirements and programme so QinetiQ can confirm suitability and access.

Sources and review
Reviewed by Arc on 1 October 2026 in Europe/London using the current official facility page, currently linked two-page product sheet, exact Haslar location listing and operator contact form. Both complete PDF pages were visually inspected. Haslar is the test site, while the Farnborough sheet imprint is a corporate enquiry address. LSSL chamber/breathing ratings, EDT fresh-water range, HETT atmospheric/salt-water conditions, cabinet ranges, HTU compartment/access/pressure and HFR reservoir pressure remain separate. No combined envelope, numerical mass flow, guaranteed item fit, current named method edition or accreditation is inferred. The published sheet email is distinguished from the current site phone and general form, without delivery/submission verification. Copyright 2021/reference QinetiQ/21/03623 and PDF creation/modification on 8 January 2026 remain separate from this review. HTML titles/canonicals and absent page-date metadata, PDF extraction, both complete page renders and all provenance are retained. The three prior discovery bodies are preserved unchanged and their raw hashes match the corresponding fresh originals. The exact versioned brochure link also returns the same PDF body. Imported coordinates and unsupported fallback contact are cleared.

The Farnborough footer address/phone is an enquiry imprint, not the Haslar test-site address. The published HaslarFacilities@QinetiQ.com email is a sheet route, without delivery verification.
Exact Haslar listing gives Haslar Marine Technology Park, Gosport, Hampshire PO12 2AG and +44 (0)23 92 335000. Other QinetiQ sites and phone numbers are not transferred. Exact HTML title/canonical and absent date meta/JSON-LD/visible times retained.
