Ships on the register which are operated by companies with bad safety records of deficiencies and detentions will be subject to very frequent inspections while ships operated by companies with good records will benefit of less inspections.
Neid registrisse kantud laevu, mis kuuluvad laevandusettevõtjatele, kellel esineb ohutuspuudujääke ja kelle laevu on kinni peetud, kontrollitakse väga sageli, ohutusnõudeid hoolikalt järgivaid laevu külastavad inspektorid aga harvem.
