Use cases
One problem, many missions: someone has to look inside first.
A penetration dive is any dive into a space with no direct way up to air: inside a wreck, a flooded cave or mine, a sunken vehicle or aircraft, or the tanks and intakes of an industrial plant. Surface-supplied air protects a diver only while every component works. It does not prevent entrapment, entanglement or differential pressure (Delta P) accidents; Delta P alone has been identified as the cause of death in about one in four diving fatalities.1 During the search of the ferry Sewol in 2014, one diver died when his air hose became entangled and another died while cutting into the hull.2,3
Whatever the mission, Fanal™ lets your divers see the hazards and objectives in a space before they go in. They make fewer dangerous entries, and the entries they do make are safer.
Salvage and wreck removal
Before a wreck can be raised, cut up or have its fuel removed, the salvors need to know what is inside, and that often means sending divers in. In 2015, salvage divers entered the sunken ferry Sewol’s vehicle decks to survey its condition and buoyancy before the lift; inside, silt up to 50 cm deep covered the decks.4,5 On the car carrier Golden Ray, divers worked inside the wreck to reach its 26 fuel tanks.6 The unknowns carry risk: the Costa Concordia salvor said “we may not know the extent of the damage 100 percent beforehand.”7 That job, first estimated at US$300 million, finished at an estimated US$2 billion.8

Counterintelligence
When a warship sinks, its sensitive equipment and documents go down with it, and they must be found and secured before anyone else reaches them. Navy divers do this work inside flooded compartments where the stakes are high. They can know a ship’s layout from its drawings, but not what the sinking did to it: collapsed deckheads, shifted fittings, blocked doors. In 1982, Royal Navy clearance divers worked for months inside the sunken destroyer HMS Coventry, more than 100 m down, recovering cryptographic equipment and top-secret documents so no hostile navy could reach them first. One diver became trapped by wiring in a cluttered passageway and had to be freed by a colleague.9,10 Fanal travels in a diver’s kit, needs no tether or surface support, and maps the wreck so divers go straight to what matters.

Fanal is designed and built in Canada and offered only to vetted buyers in Canada and allied countries. It is not designed or offered as a weapon or weapon platform.
Search and rescue (SAR)
When a vessel capsizes or an aircraft goes into the water, people can survive for days in air trapped inside. In 2013 the cook of the capsized tug Jascon-4 survived about 60 hours in an air pocket 30 m down, until divers searching the wreck heard him.11 Rescue divers must search a dark, upside-down maze to find them, and every wrong turn costs time and risk. Fanal can search ahead of the divers and show them where the air pockets and the survivors are.
- Who
- Coast guard, police and search and rescue dive teams
- Mission
- Search a capsized vessel or sunken aircraft for survivors in air pockets, ahead of the divers
- Value
- Divers go straight to the survivors, with fewer dangerous entries
Also in reach
The same vehicle, other flooded spaces.
Industrial intakes and penstocks
Map water intakes, penstocks and tanks before a diver enters, for the contractors who maintain them.
Fuel and pollution removal
Find fuel, oil and hazardous cargo inside a wreck before anyone goes in to remove it.
Exploration and science
Map flooded caves and historic wrecks. We plan a community programme to make Fanal available to non-profit rescue and exploration teams.
