Stress in a salvage faying face of a submarine while mooring a recovery vessel

Kyzioł L.

Journal of Polish CIMAC

2012

Vol. 7, no 2

97-105

The article presents stress distribution in a seat face of a submarine while docking a submergence recovery vessel. Rescue faces (salvage faying faces) in submarines are used to dock emergency vehicles. Both submergence recovery vessels and submarines possess special seat faces which enable the transition of a crew from a sunken ship to an emergency vehicle. Due to corrosion environment, seat faces in submarines undergo degradation, which requires periodic inspection of their condition. With accordance to the valid standards, the minimum thickness of faying faces cannot be less than 25,4 mm on account of the stresses and dislocations. Seat measurements made it possible to carry out simulation studies to determine their strength, distribution of stresses and displacements. The obtained results of seat strength allow for a submersion of a submarine to a maximum depth according to the current standards.
