Availability, Reliability and Security

Abstract

Uvjeti rada i sigurnost plovidbe postavljaju na brodsku elektroničku opremu vrlo stroge tehničke zahtjeve s posebnim naglaskom na pouzdanost i kvalitetu te opreme. Od te opreme zahtijeva se da besprijekorno funkcionira u klimatološkim i tehničkim uvjetima. Palubna oprema mora udovoljavati oštrijim zahtjevima jer je u nepovoljnijim uvjetima od one u unutrašnjosti broda. Oprema na brodu koja utječe na sigurnost plovidbe testira se prema propisima pripadnoga klasifikacijskog društva o čemu društvo izdaje svjedodžbu. Statistički podaci pokazuju da je broj ozljeda kao i broj smrtnih slučajeva, na niskom naponu znatno veći od broja ozljeda na visokom naponu. Na plovnim objektima uglavnom se koristi radijalni sustav razvoda, dok se prstenasti sustav upotrebljava rijetko, i to pretežno na objektima specijalne namjene.Working conditions and safety of navigation set on ship equipment very strict tehnical requirements with special emphasis on the reliability and quality of the equipment. The equipment on bord is required to function flawlessly under climatic and tehnical conditions. Deck equipment has to comply with the sharpest requirements because it is less favorable than those int he interior oft he ship. Equipment on bord which affects on the safety of navigation shall be tested according to the regulations oft he relevant classification society for wich the society issues a certificate. Statistics show that the number of injuries as well as the number of deaths on the low voltage is isgnificantly higher than the number of injuries on high voltage. On floating facilities the sloping system is mainly used, while annular systems is used rarely, and mainly on special purpose objects
