I-Shidightightight yeSeel ibhekisa kwintsimbi yezakhiwo ze-hull, ezibhekisele kwintsimbi esetyenziselwa ukwenza izakhiwo ezikhoyo eziveliswayo. Ihlala i-odolwa, icwangcisiwe kwaye ithengiswa njengentsimbi ekhethekileyo. Inqanawa enye ibandakanya iipleyiti zenqanawa, intsimbi eqinileyo, njl.
Okwangoku, iinkampani ezinkulu zensimbi kwilizwe lam zinemveliso, kwaye zinokuvelisa iimveliso zensimbi yaselwandle ngokokudinga amazwe ahlukeneyo, njenge-United States, iNorway, iJamani, iFrance, njl njl.

(1) Inkcazo eyahlukeneyo
Intsimbi yesakhiwo yee-hullls yahlulahlulwe yangamanqanaba amandla ngokwesivuno sabo esincinci: amandla aqhelekileyo ngentsimbi ye-Stell kunye nentsimbi ephakamileyo.
Intsimbi yamandla ngokubanzi echazwe nguMbutho woLawulo lwe-China wohlulwe waba ngamanqanaba amane asemgangathweni: A, B, D, ne-E; Intsimbi enesiphene esiphakamileyo esichazwe yi-China yolawulo loluntu sahlulahlulwe sangamanqanaba amathathu amandla kunye namanqanaba amane asemgangathweni:

(3) Izilumkiso zokuhanjiswa kunye nokwamkelwa kweemveliso zensimbi yaselwandle:
1. Uphononongo lwesatifikethi semgangathweni:
Umzi-mveliso wensimbi kufuneka uhambise izinto ngokweemfuno zoMsebenzisi kunye neenkcazo ekuvunyelwene ngazo kunye nokubonelela ngesatifikethi somgangatho. Isatifikethi kufuneka siqulethe oku kulandelayo:
(1) iimfuno zokuchaza;
(2) Inombolo yerekhodi esemgangathweni kunye nenombolo yesatifikethi;
(3) Inombolo ye-Witch yeNqanaba, inqanaba lobugcisa;
(4) Ubume bemichiza kunye neepropathi zoomatshini;
(5) Isatifikethi sokuvunywa kuluntu lokuhlelwa kunye nokutyikitywa komvavanyi.
2. Uphengululo lwemisebenzi:
Ukuhanjiswa kwentsimbi yaselwandle, into ebonakalayo kufuneka inophawu lomenzi, njl. Ngokwenye ngokukodwa:
(1) Isiko lokuvuma ukuvunywa kombutho;
.
(3) Inkangeleko igudileyo kwaye igudile, ngaphandle kweziphene.
