IEC 60092-352:2005

This standard provides the basic requirements for the choice and installation of cables intended for fixed electrical systems on board ships at voltages (U) up to and including 15 kV.
The reference to fixed systems includes those that are subjected to vibration (due to the movement of the ship) or movement (due to motion of the ship) and not to those that are intended for frequent flexing. Cables suitable for frequent or continual flexing use are detailed in other IEC specifications e.g. IEC 60227 and IEC 60245, and their uses on board ship is restricted to those situations which do not directly involve exposure to a marine environment e.g. portable tools or domestic appliances.
