Icyuma cyubaka muri rusange bivuga ibyuma byimiterere ya Hull, bivuga ibyuma byakoreshwaga mu gukora inyubako zihujwe hakurikijwe ibisabwa na serivise yo kubara. Bikunze gutegekwa, biteganijwe kandi bigurishwa nkibiti bidasanzwe. Ubwato bumwe burimo amasahani yubwato, ibyuma bifatika, nibindi.
Kugeza ubu, amasosiyete menshi y'icyuma mu gihugu cyanjye afite umusaruro, kandi arashobora kubyara ibicuruzwa byo mu nyanja akurikije abakoresha mu bihugu bitandukanye, nk'Ubudage, Ubudage, Ubudage, ibibi ni ibi bikurikira:

(1) Ibisobanuro bitandukanye
Icyuma cyukuri kuri Hulls zigabanyijemo imbaraga ukurikije umusaruro ntarengwa: imbaraga rusange zubaka ibyuma n'imbaraga nyinshi zubaka.
Imbaraga rusange zubaka ibyuma byagenwe na societe yishyurwa Ubushinwa bigabanyijemo urwego enye: A, B, D, na E; Ibyuma byinshi byubatswe byerekanwe na societe yishyurwa Ubushinwa bugabanijwemo urwego rwimbaraga eshatu ninzego zine nziza:
| A32 | A36 | A40 |
| D32 | D36 | D40 |
| E32 | E36 | E40 |
| F32 | F36 | F40 |
(2) imiterere ya mashini n'imiti
Imitungo ya mashini n'imiti ifite imbaraga rusange hull steel

(3) Guhabwa Gutanga no kwemera ibicuruzwa bya Marine:
1. Gusubiramo icyemezo cyiza:
Uruganda rwibyuma rugomba gutanga ibicuruzwa ukurikije ibyo ukoresha hamwe nibisobanuro byumvikanye mumasezerano no gutanga icyemezo cyumwimerere. Icyemezo kigomba kuba kirimo ibintu bikurikira:
(1) Ibisabwa byerekana;
(2) Numubare mwiza wandika numero na numero yemewe;
(3) itanura nimero, urwego rwa tekiniki;
(4) imiti ifite imiti na moshini;
(5) Icyemezo cyo kwemerwa na societe y'ibanze no gusinya umushakashatsi.
2. Isubiramo ryumubiri:
Kubitangirira ibyuma byo mu nyanja, ikintu gifatika kigomba kugira ikirango cyabikoze, nibindi byihariye:
(1) Shyira ahagaragara sosiyete yemera;
.
(3) Kugaragara biroroshye kandi byoroshye, nta nenge.
