Kuchokera ku nyali zolimba za m'madzi mpaka ku nyali za fulorosenti zapamadzi zomwe sizingawononge mphamvu, timakupatsirani zosankha zomwe mungathe kusintha, mitengo yampikisano, komanso magwiridwe antchito odalirika.
Ku BozhouMarine, timaphatikiza ukatswiri, mtundu komanso luso kuti tipereke zinthu zowunikira zam'madzi zomwe zimakwaniritsa miyezo yapamwamba kwambiri yamakampani.
Ndife ovomerezeka ndi ISO ndipo timatsatira miyezo yapadziko lonse lapansi, kuwonetsetsa kuti zinthu zowunikira zam'madzi ndizokhazikika, zodalirika komanso zotetezeka.
Kuchokera pamagalasi kupita ku magetsi oyendera, timapereka mapangidwe ogwirizana kuti akwaniritse zofunikira za sitimayo komanso zomwe kasitomala amakonda.
Pokhala ndi zaka zambiri monga ogulitsa odalirika owunikira zowunikira panyanja, timamvetsetsa zovuta zapadera zomwe zimachitika m'madzi am'madzi ndikupereka mayankho anzeru.
ATEX vs IECEx ya magetsi oteteza kuphulika kwa nyanja: Lamulo la ATEX silimaphatikizapo zombo zoyenda m'nyanja, kotero kuvomerezedwa kwa IECEx pamodzi ndi gulu la anthu odziwika bwino kumasankha zomwe zipambana kafukufukuyu.
Kufotokozera kwa Marine Morse Code Signaling: Malamulo a nyali zowunikira masana za SOLAS, muyezo wa ma cd 60,000, zilembo 40 pamphindi, ndi momwe mungasankhire nyali yoyenera.
Buku lotsogolera kusintha mababu amagetsi a m'nyanja: dziwani maziko a mababu a bayonet, wedge, ndi screw, fananizani magetsi a 12V/24V/120V, ndikusinthanitsa mababu mosamala pa sitima iliyonse lero.
