Umuyoboro w'icyuma cyo mu nyanja, ukoreshwa mu kubaka ubwato na superheater.
Imiyoboro y'icyuma idafite ubwato bwo kubaka ubwatoreba imiyoboro y'ibyuma yateguwe kandi ikorerwa kubotsa marine, superheater hamwe na sisitemu yumuvuduko. Imiyoboro yubwubatsi bwubwato irashobora gukoreshwa cyane muri CCS, DNV, LR, GL, ABS, BV, RINA, NK nandi mato kimwe nuburinganire bwigihugu cyUbushinwa.

Ubwiza bwibicuruzwa bwizewe. Yoherezwa kandi mu bihugu n'uturere twinshi muri Amerika y'Amajyaruguru, Amerika y'Epfo, Uburayi, Uburasirazuba bwo hagati, Aziya y'Amajyepfo y'Uburasirazuba, Ositaraliya na Aziya yo hagati. Ibicuruzwa bikoreshwa cyane mubikorwa bitandukanye byubaka ibyuma byubaka, ubwubatsi bwingufu za kirimbuzi, ubwubatsi bwinyanja, ubwubatsi bwikiraro cyubwubatsi, imashini yubwubatsi nogukora ibikoresho, umusaruro wibikoresho bya metallurgji nizindi nzego. Ibindi bicuruzwa ni: igitutu cyumuvuduko mwinshi, imiyoboro yamenagura amavuta, ifumbire mvaruganda yumwuga mwinshi, ibyuma byumuyoboro, amavuta ya peteroli, ibyuma bishyushye bikarishye, ibyuma bikonjesha bikonje, imiyoboro yabugenewe, ibyuma byerekana ibyuma, ibyuma bya zinc, ibyuma bya zinc hamwe nibindi bitandukanye umuyoboro ushyigikira ibicuruzwa.
Isosiyete iha agaciro kanini ubuziranenge bwibicuruzwa, ishora imari cyane mu kumenyekanisha ibikoresho n’inzobere bigezweho, kandi ikora ibishoboka byose kugira ngo abakiriya babone ibyo bakeneye mu gihugu ndetse no mu mahanga.
Ibirimo birashobora kugabanwa mubice: ibigize imiti, imbaraga zitanga umusaruro, imbaraga zingana, imitungo yingaruka, nibindi
Muri icyo gihe, isosiyete irashobora kandi gukora kumurongo wo gutahura inenge no gufatira hamwe nubundi buryo bwo kuvura ubushyuhe ukurikije ibyo abakiriya bakeneye.
