The use of sound signals for attention and information in the most efficient way is not so simple from all aspects.
That is the reason behind the regulations determined through the 'International Convention for Preventing Collisions at Sea, 1972'. Nowadays, each vessel from 12 metres and more (length over all) must
be equipped with sound signal appliances which are type approved according to the IMO regulations.
Hence, one part of the responsibility is the manufacturer's, but still one important part is the shipowner's regarding:
- the choice of appropriate equipment for the
vessel In question,
- the installation and use.
