BAP Pacocha (SS-48) was a submarine of the Marina de Guerra del Perú named for the 1877 Battle of Pacocha, in which the Peruvian ironclad Huascar clashed with the Royal Navy. Formerly USS Atule (SS-403), a Balao-class submarine with a GUPPY IA upgrade, she had been sold to Peru and commissioned on 28 May 1974. She was rammed and sunk by a fishing trawler on 26 August 1988.
Saturation diving is diving for periods long enough to bring all tissues into equilibrium with the partial pressures of the inert components of the breathing gas used. It is a diving mode that reduces the number of decompressions divers working at great depths must undergo by only decompressing divers once at the end of the diving operation, which may last days to weeks, having them remain under pressure for the whole period. A diver breathing pressurized gas accumulates dissolved inert gas used in the breathing mixture to dilute the oxygen to a non-toxic level in the tissues, which can cause potentially fatal decompression sickness if permitted to come out of solution within the body tissues; hence, returning to the surface safely requires lengthy decompression so that the inert gases can be eliminated via the lungs. Once the dissolved gases in a diver's tissues reach the saturation point, however, decompression time does not increase with further exposure, as no more inert gas is accumulated.
A diving support vessel is a ship that is used as a floating base for professional diving projects. Basic requirements are the ability to keep station accurately and reliably throughout a diving operation, often in close proximity to drilling or production platforms, for positioning to degrade slowly enough in deteriorating conditions to recover divers without excessive risk, and to carry the necessary support equipment for the mode of diving to be used.
INS Sindhurakshak was a Russian-made Kilo-class 877EKM (Sindhughosh-class) diesel-electric submarine of the Indian Navy. Commissioned on 24 December 1997, it was the ninth of the ten Kilo-class submarines in the Indian Navy. On 4 June 2010, the Indian Defence Ministry and Zvezdochka shipyard signed a contract worth US$80 million to upgrade and overhaul the submarine. After the overhaul, it returned to India from Russia between May and June 2013.
PNS/M Ghazi (S–130), SJ, was a Tench-class diesel-electric submarine, the first fast-attack submarine in the Pakistan Navy. She was leased from the United States Navy in 1963.
A diving chamber is a vessel for human occupation, which may have an entrance that can be sealed to hold an internal pressure significantly higher than ambient pressure, a pressurised gas system to control the internal pressure, and a supply of breathing gas for the occupants.
Diver rescue, usually following an accident, is the process of avoiding or limiting further exposure to diving hazards and bringing a diver to a place of safety. A safe place generally means a place where the diver cannot drown, such as a boat or dry land, where first aid can be administered and from which professional medical treatment can be sought. In the context of surface supplied diving, the place of safety for a diver with a decompression obligation is often the diving bell.
The Marine Commando Force (MCF), abbreviated to MARCOS, are the special forces of the Indian Navy. The MARCOS were originally named Indian Marine Special Force, which was later changed to Marine Commando Force to impart "an element of individuality" to it, according to the Indian Navy. The abbreviation 'MARCOS' was coined afterwards.
An aquanaut is any person who remains underwater, breathing at the ambient pressure for long enough for the concentration of the inert components of the breathing gas dissolved in the body tissues to reach equilibrium, in a state known as saturation.
The Sri Lanka Navy (SLN) is the naval arm of the Sri Lanka Armed Forces and is classed as the country's most vital defence force due to its island geography. It is responsible for the maritime defence of the Sri Lankan nation and its interests. The role of the Sri Lanka Navy is to conduct operations at sea for the defence of the nation and its interests and conduct prompt and sustainable combat operations at sea in accordance with the national policies.
Australian Submarine Rescue Vehicle Remora was a submarine rescue vehicle used by the Royal Australian Navy (RAN) between 1995 and 2006. The name comes from the remora, a small fish that can attach itself to larger marine life, and has the backronym "Really Excellent Method of Rescuing Aussies".
The United States Navy Experimental Diving Unit is the primary source of diving and hyperbaric operational guidance for the US Navy. It is located within the Naval Support Activity Panama City in Panama City Beach, Bay County, Florida.
Captain Albert Richard Behnke Jr. USN (ret.) was an American physician, who was principally responsible for developing the U.S. Naval Medical Research Institute. Behnke separated the symptoms of Arterial Gas Embolism (AGE) from those of decompression sickness and suggested the use of oxygen in recompression therapy.
INS Kamorta is the first of four anti-submarine Kamorta-class stealth corvettes which has been built for the Indian Navy.
SLINEX are a series of naval exercises between the Indian Navy and the Sri Lanka Navy. The first SLINEX exercise took place in 2005. The eighth edition took place in 2020.
The following outline is provided as an overview of and topical guide to underwater diving:
A built-in breathing system is a source of breathing gas installed in a confined space where an alternative to the ambient gas may be required for medical treatment, emergency use, or to minimise a hazard. They are found in diving chambers, hyperbaric treatment chambers, and submarines.
The U.S. Navy Diving Manual is a book used by the US Navy for diver training and diving operations.
