※船体の引き上げは無理とのこと

Individual escape:
The fact that the Kursk has grounded about 100 metres down probably rules out any escape by the crew using individual survival suits, even if these are carried in sufficient numbers. Water pressure at such a depth would be crushing and would make any such move extremely dangerous. Western experts also say that the crew would need a high level of training to leave the submarine in this way.

Refloating:
There could be an attempt to raise and refloat the submarine using a surface ship with underwater air pipes, though given its massive weight and size, and the fact that it has probably taken on water, this would be hugely difficult. Western naval sources say that this would not be the preferred method for a Nato navy. If the Kursk were badly damaged, this kind of operation could make matters worse, even splitting the vessel open and releasing radioactive material.

Rescue by submarine:
Russia has deep-diving mini submarines like those used in the past to investigate the remains of the Titanic. Such vessels, if available, could operate as miniature submarine life-boats, attaching to the Kursk's escape hatch and ferrying its crew out in small groups. But these vessels are reportedly based in the Baltic and could take several days to arrive. Another problem could be that the escape hatch on the Kursk has sustained damage and can no longer be operated.

Diving bell:
Rescuers could deploy a type of Russian diving bell, known as the Kolokol, which can carry 10-15 people back to the surface at a time. The bell has an airlock to allow the crew to acclimatise to pressure changes as they float to the surface, avoiding decompression sickness or the bends. The success of such an operation would be affected by sea conditions, underwater currents and the angle of the submarine lying on the sea floor.
