Atmosphere sampler and DSVDS

Where an intervention vessel is able to reach a DISSUB in advance of a rescue vessel, the atmosphere sampler and distressed submarine ventilation and decompression system (DSVDS) may both be utilised to prepare the submarine for rescue, and to augment the onboard life support for as long as it is required.

Both interface with the DISSUB’s high salvage point (HSP) or nation-specific ventilation interface.

The air quality of a DISSUB may be noxious and communication with the crew may not be possible. In this situation, prior to mating with a rescue vehicle or attempting salvage, a sample of the internal atmosphere may be taken via the DISSUB’s high salvage point and used to inform command decision making.

• Lightweight universal mounting for many remotely operated vehicles (ROV).
• Simple in operation.
• Connects to a DISSUB’s high salvage point or ventilation connection.
• Flushes pipework system prior to collection of sample.
• Maintains a safe pressure boundary upon completion.
• Retains ability to connect further equipment without compromising hull integrity.

JFD’s DSVDS system can be used to perform the following tasks:

• Stabilise conditions on the DISSUB prior to rescue.
• Begin decompression within DISSUB.
• Control and reduce DISSUB internal pressure to enable escape.
• Provide additional air to evacuate water prior to salvage or recovery.

Key Particulars

• Fully containerised and optimised for deployment by land, air and sea.
• Designed for rapid deployment to vessels of opportunity.
• Suited to use with DP2 capable vessels, or in three or four-point mooring configurations.
• Operable in conditions up to sea state 5.

JFD can provide interface adapter kits for NATO STANAG 1450 compliant, and nation-specific ventilation connections or high salvage points enabling the equipment described above to be used with submarines from most nations. For maximum compatibility, JFD can provide a set of adapters in a single self-contained peli case for ease of transportation.

JFD is the sole-supplier of UK-type HSP connectors which have the advantage of being operable by an ROV.
