	RMS TITANIC, INC
		When all is ready, the submersible is launched by hydraulic crane to the surface of the sea and set free from the support vessel.
		Air is released from the ballast tanks and the sub sinks freely to the ocean floor; a journey of two and one half hours and an equal number of miles.
		A palpable sense of anticipation hovers over the support vessel until the capsule is spotted breaking the surface.

	Diving support vessel - Wikipedia, the free encyclopedia
		A diving support vessel is a ship that is used as a floating base for professional diving projects.
		A diving bell would transport the divers between the saturation system and the work site lowered through a "moon-pool" in the bottom of the ship, usually with a support structure "cursor" to support the diving bell through the turbulent waters near the surface.
		One of the most successful diving support vessels of the 1980s was the SSSV Uncle John operated by Comex Houlder diving.

	Saturation diving - Wikipedia, the free encyclopedia
		Saturation diving is a diving technique that allow divers to remain at great depth for long periods of time, by living under pressure in special living chamber complexes affixed to a diving support vessel, oil platform or other floating work station.
		This type of diving allows for greater economy of work and enhanced safety for the divers because the diving team is compressed to depth during the descent just once, where they remain, living in a pressurized environment equal to the depth of water they will be working in.
		At the completion of work or a mission, the saturation diving team is decompressed gradually back to atmospheric pressure by the slow venting of system pressure, thus the process involves only one ascent, thereby mitigating the time-consuming and comparatively risky process of in-water, staged decompression normally associated with non-saturation ("bounce diving") operations.

	Gas mixer for use on N Sea diving support vessel
		The vessel deploys divers to depths between the surface and 300 meters.
		The vessel operates a diving technique to maximise the working time of the divers, which involves them living at a pressure equivalent to the water pressure at which they are working.
		The divers live in a 15 man saturation dive chamber on board the vessel and transfer at the same pressure to a diving bell, which is then deployed to the working depth.

	Diving Operations (Site not responding. Last check: )
		Once a month, a dive training day was organised for the divers to practice search techniques, and to carry out clearance dives on bridges and jetties, searching for stolen items, firearms or similar items.
		The Dive Squad has state-of-the-art facilities, such as a heated drying room for wet equipment; a high speed compressor for quick cylinder fills; communications (voice) between diver and surface; and high powered search lighting for underwater and surface operations.
		The divers are often required to dive in adverse climatic conditions, nil visibility areas, and contaminated waters such as the upper Swan River, dams, caves, wells and mine shafts.

		The vessel's speed was reduced and the autopilot adjusted to bring her head into the wind.
		The vessel was certified, crewed, equipped and operated in accordance with existing regulations for a vessel of her size, type and the trade in which she was engaged.
		Prior to re-establishing main and auxiliary power onboard the vessel, an inspection of the quick-closing fuel valves by the chief engineer revealed that valves to both engine rooms were in the tripped position.

	HMCS Cormorant - Canada's Diving Support Vessel
		She distinguished herself in support of battles such as the Plains of Abraham, American War of Independence, the French Revolution and the China War, where the expression, "Blood is thicker than water" grew from her efforts which were in vain.
		Cormorants are excellent divers, at home in both salt and fresh water, and are known for their wariness and alertness to danger.
		Then late in 1977 she was turned over to the Davie Shipbuilding Co., Lauzon, Québec, refitted and converted as a submarine support diving vessel and commissioned in November 1978 as "HMCS CORMORANT".

	Diver location trials: Recommendations
		The relocation potential of folding flags are optimised when observed from a diving support vessel, and maximised when the search aspect is abeam to the prevailing wind direction.
		If a dive plan assessment identifies a high risk of in-water divers becoming separated from the diving support vessel, particular consideration must be taken of the prevailing environmental conditions, the number of in-water divers at any given time, and the location devices that the divers should carry.
		Divers performing shellfish diving operations should always undertake a risk assessment on a daily basis taking the above factors into account with particular attention focused on the dive site, number of divers to be deployed and the separation distance of deployment.

		The dive tables most commonly used by the Hyperbaric Medicine Unit are explained in more detail in the dive tables section.
		In SCUBA diving, O2 enriched gas mixes are often used in order to help flush out nitrogen from the body more rapidly, and divers also encounter raised atmospheric pressure.
		Accurate dive profiles depend on knowing the exact percentage of oxygen in Nitrox, which is produced as either 32% (Nitrox I) or 36% (Nitrox II).

	MFR Requirements Navy - Ministry of Defence NZ
		Naval vessels also provide the capability to board, inspect and arrest or conduct hot pursuit of offending vessels that may be engaged in illegal or unregulated activities that are not identifiable from the air, or that have been identified by an aircraft and require a response.
		This process had two objectives: to identify the type(s) of vessels that would be required to meet the surface surveillance requirement; and to identify the number of vessels that would be needed to meet the requirement.
		While all Navy vessels have a towage capacity, especially for smaller vessels, the propulsion characteristics of a frigate mean that it would not be sufficient to render assistance and prevent a disabled large bulk carrier or tanker from being driven ashore.

	Heavy-Walled Vessel Diving-Underwater Exploration-University of Wisconsin Sea Grant
		Such vessels include: the bathysphere -- an unpowered hollow steel ball lowered from the surface support ship by steel cable; the bathyscaphe -- a bathysphere with buoyancy control so that cable is not needed for descent and ascent; and the submarine -- which can travel great distances in any direction under its own power.
		All these vessels require a system to provide fresh air (usually by adding oxygen to the existing air) and to get rid of exhaled carbon dioxide (with soda lime, lithium hydroxide, or similar chemical compounds that take up carbon dioxide).
		A modern extension of the one-atmosphere vessel is the self-contained armored diving suit, flexible yet able to withstand pressures at depth.
