Injini eyisiza yomkhumbi ivamise ukusetshenziselwa ukukhiqiza amandla lapho umkhumbi umile ukuze uhlangabezane nesidingo samandla omkhumbi.Isidingo samandla sezinhlobo ezahlukene zemikhumbi sihlukile.Ngaphezu kwesidingo samandla sasekhaya sabasebenzi, imikhumbi yamabhokisi nayo idinga ukuhlinzeka ngamandla ezitsheni eziqandisiwe;Umkhumbi wezimpahla ojwayelekile nawo udinga ukuhlinzeka ngamandla ku-crane ebhodini, ngakho-ke kunomehluko omkhulu womthwalo esidingweni sokuhlinzekwa kwamandla kwezinhlobo ezahlukene zemikhumbi egibelayo, futhi ngezinye izikhathi kungase kube nesidingo esikhulu somthwalo wamandla.Injini yokusiza yasolwandle izokhipha inqwaba yezinto ezingcolisayo ngesikhathi sokusebenza, ikakhulukazi okuhlanganisa i-carbon dioxide (CO2), ama-nitrogen oxides (NO) nama-sulphur oxides (SO), azongcolisa indawo ezungezile.Idatha yocwaningo ye-International Maritime Organisation (IMO) ikhombisa ukuthi imikhumbi esebenza ngodizili emhlabeni wonke ikhipha amashumi ezigidi zamathani we-NO ne-SO emkhathini minyaka yonke, okubangela ukungcola okubi kakhulu;Ukwengeza, inani eliphelele le-CO elikhishwa izinto zokuthutha zasolwandle emhlabeni wonke likhulu, futhi inani eliphelele le-CO2 elikhishiwe lidlule ukukhishwa kwamagesi abamba ukushisa kwaminyaka yonke emazweni asohlwini lweSivumelwano sase-Kyoto;Ngesikhathi esifanayo, ngokusho kwedatha, umsindo okhiqizwa ukusetshenziswa kwemishini eyisizayo yimikhumbi echwebeni uyophinde ubangele ukungcoliswa kwemvelo.
Njengamanje, amanye amachweba athuthukile emhlabeni jikelele asebenzise ubuchwepheshe bamandla ogwini ngokulandelana futhi abuphoqelela ngendlela yomthetho.I-Port Authority yase-Los Angeles yase-United States iphasise umthetho [1] wokuphoqelela zonke izikhumulo ezingaphansi kwendawo yayo ukuba zisebenzise ubuchwepheshe bamandla ogwini;NgoMeyi 2006, Ikhomishini YaseYurophu yaphasisa umthethosivivinywa 2006/339/EC, owaphakamisa ukuthi amachweba e-EU asebenzise amandla ogwini ukuze amise imikhumbi.E-China, uMnyango Wezokuthutha nawo unezidingo ezifanayo zokulawula.Ngo-April 2004, uMnyango Wezokuthutha wangaphambili wakhipha Imithethonqubo Yokusebenza Nokuphathwa Kwechweba, eyahlongoza ukuthi ugesi wasogwini nezinye izinsiza kufanele zihlinzekwe emikhunjini endaweni yechweba.
Ngaphezu kwalokho, ngokombono wabanikazi bemikhumbi, ukukhuphuka kwentengo kawoyela ongahluziwe emhlabeni wonke okubangelwa ukushoda kwamandla nakho kwenza izindleko zokusebenzisa uwoyela uphehla ugesi emikhumbi esondela echwebeni zikhuphuke ngokuqhubekayo.Uma kusetshenziswa ubuchwepheshe bamandla ogwini, izindleko zokusebenza zemikhumbi esondela echwebeni zizoncishiswa, kube nezinzuzo ezinhle kwezomnotho.
Ngakho-ke, ichweba lamukela ubuchwepheshe bamandla ogwini, olungagcini nje ngokuhlangabezana nezidingo zikazwelonke nezimboni zokongiwa kwamandla kanye nokunciphisa ukungcola, kodwa futhi lihlangabezana nezidingo zamabhizinisi zokunciphisa izindleko zokusebenza, ukuthuthukisa ukuncintisana kwetheminali kanye nokwakha "ichweba eliluhlaza".
