Attention! The supporting device 94350 can be used for piston overhauling
work at calm sea only, however, in no case this may serve as storage place
during the voyage!
Moreover, always bear in mind, that the passage between engine and supporting
device is limited (e.g. as possible escape route) on the platform.
