Insimbi yokwakha umkhumbi ngokuvamile ibhekisela kunsimbi yezakhiwo ze-hull, okubhekisela ezinsimbi ezisetshenziselwa ukwakha izakhiwo ze-hull ezikhiqizwa ngokuhambisana nezidingo zokucaciswa kokwakhiwa komphakathi. Ivame uku-oda, ihlelwe futhi ithengiswe njengensimbi ekhethekile. Umkhumbi owodwa uhlanganisa amapuleti omkhumbi, insimbi emise okwensimbi, njll.
Njengamanje, izinkampani zensimbi eziningana ezinkulu ezweni lami zinokukhiqiza, futhi zingakhiqiza imikhiqizo yensimbi yasolwandle ngokwezidingo zabasebenzisi emazweni ahlukene, njenge-United States, Norway, Japan, Germany, France, njll. Imininingwane imi kanje:
| Izwe | Okujwayelekile | Izwe | Okujwayelekile |
| I-united states | I-ABS | China | I-CCS |
| EJalimane | GL | eNorway | I-DNV |

(1) Imininingwane ehlukahlukene
Insimbi yesakhiwo yama-hulls ihlukaniswe ngamaleveli wamandla ngokuya ngephoyinti lawo elincane lesivuno: amandla ajwayelekile ensimbi yesakhiwo namandla aphezulu ensimbi yesakhiwo.
Insimbi yesakhiwo samandla evamile ecaciswe yi-China Classification Society ihlukaniswe ngamaleveli amane ekhwalithi: A, B, D, kanye no-E; insimbi yesakhiwo enamandla aphezulu ecaciswe yi-China Classification Society ihlukaniswe ngamaleveli amathathu wamandla namazinga ekhwalithi amane:
| A32 | A36 | A40 |
| D32 | D36 | D40 |
| E32 | E36 | E40 |
| F32 | F36 | F40 |

(3) Izinyathelo zokuqapha ukulethwa nokwamukelwa kwemikhiqizo yensimbi yasolwandle:
1. Ukubuyekezwa kwesitifiketi sekhwalithi:
Imboni yensimbi kufanele ilethe izimpahla ngokuvumelana nezidingo zomsebenzisi kanye nemininingwane okuvunyelwene ngayo kwinkontileka futhi inikeze isitifiketi sekhwalithi sangempela. Isitifiketi kufanele siqukathe okuqukethwe okulandelayo:
(1) Izidingo zokucaciswa;
(2) Inombolo yerekhodi lekhwalithi kanye nenombolo yesitifiketi;
(3) Inombolo yenqwaba yesithando somlilo, izinga lobuchwepheshe;
(4) Ukwakheka kwamakhemikhali kanye nezakhiwo zemishini;
(5) Isitifiketi sokugunyazwa esivela emphakathini wokuhlukanisa kanye nesiginesha yomhloli.
2. Ukubuyekeza okungokoqobo:
Ukulethwa kwensimbi yasolwandle, into ebonakalayo kufanele ibe nelogo yomkhiqizi, njll. Ngokukhethekile:
(1) Uphawu lokugunyaza umphakathi ngezigaba;
(2) Sebenzisa upende ukuze uhlaka noma unamathisele uphawu, okuhlanganisa nemingcele yobuchwepheshe njengalezi: inombolo yenqwaba yesithando somlilo, izinga elijwayelekile lokucaciswa, ubude nobukhulu bobubanzi, njll.;
(3) Ibukeka bushelelezi futhi bushelelezi, ngaphandle kwamaphutha.
