Kugwiritsa ntchito ukadaulo wolumikizana ndi zombo zapanyanja padoko

Injini yothandizira sitimayo nthawi zambiri imagwiritsidwa ntchito popanga mphamvu sitimayo ikaima kuti ikwaniritse mphamvu ya sitimayo.Kufuna mphamvu kwa mitundu yosiyanasiyana ya zombo ndi yosiyana.Kuphatikiza pa kufunikira kwa mphamvu zapakhomo kwa ogwira ntchito, zombo zapamadzi zimafunikanso kupereka mphamvu kuzitsulo zafriji;Sitima yonyamula katundu wamba ikufunikanso kupereka mphamvu kwa crane yomwe ili m'bwaloli, chifukwa chake pali kusiyana kwakukulu pakufunika kwamagetsi amitundu yosiyanasiyana ya zombo zonyamula katundu, ndipo nthawi zina pangakhale kufunikira kwakukulu kwamagetsi.Injini yothandizira yam'madzi idzatulutsa zowononga zambiri pogwira ntchito, makamaka kuphatikiza mpweya woipa (CO2), nitrogen oxides (NO) ndi sulfure oxides (SO), zomwe zidzaipitsa malo ozungulira.Deta yofufuza ya International Maritime Organisation (IMO) ikuwonetsa kuti zombo zoyendera dizilo padziko lonse lapansi zimatulutsa matani mamiliyoni ambiri a NO ndi SO mumlengalenga chaka chilichonse, zomwe zimawononga kwambiri;Kuonjezera apo, kuchuluka kwa CO2 komwe kumatulutsidwa ndi kayendedwe ka panyanja padziko lonse ndi kwakukulu, ndipo kuchuluka kwa CO2 komwe kumatulutsa kwadutsa mpweya wapachaka wa mpweya wowonjezera kutentha kwa mayiko omwe ali mu Kyoto Protocol;Panthawi imodzimodziyo, malinga ndi deta, phokoso lopangidwa ndi kugwiritsa ntchito makina othandizira ndi zombo padoko lidzachititsanso kuipitsa chilengedwe.

Pakadali pano, madoko ena otsogola padziko lonse lapansi atengera umisiri wamagetsi am'mphepete mwa nyanja motsatizana ndikuukhazikitsa mwalamulo.Bungwe la Port Authority la Los Angeles ku United States lakhazikitsa lamulo [1] kukakamiza ma terminals onse omwe ali m'gawo lake kuti agwiritse ntchito luso laukadaulo wamagetsi am'mphepete mwa nyanja;Mu May 2006, European Commission idapereka lamulo la 2006/339/EC, lomwe linanena kuti madoko a EU agwiritse ntchito mphamvu za m'mphepete mwa nyanja pokwerera zombo.Ku China, Unduna wa Zamayendedwe ulinso ndi zofunikira zowongolera zofananira.Mu Epulo 2004, Unduna wakale wa Zamsewu udapereka Malamulo okhudza Kugwira Ntchito ndi Kuwongolera Madoko, omwe adaganiza kuti magetsi a m'mphepete mwa nyanja ndi ntchito zina ziyenera kuperekedwa kwa zombo zapadoko.

Kuphatikiza apo, malinga ndi momwe eni ake a zombo, kukwera kwamitengo yamafuta osakanizidwa padziko lonse lapansi chifukwa cha kusowa kwa mphamvu kumapangitsanso kuti mtengo wogwiritsa ntchito mafuta opangira magetsi opangira zombo zoyandikira doko uzikwera mosalekeza.Ngati teknoloji yamagetsi ya m'mphepete mwa nyanja ikugwiritsidwa ntchito, ndalama zogwiritsira ntchito zombo zoyandikira doko zidzachepetsedwa, ndi zabwino zachuma.

Choncho, dokoli limagwiritsa ntchito teknoloji yamagetsi ya m'mphepete mwa nyanja, zomwe sizimangokwaniritsa zofunikira za dziko ndi mafakitale pofuna kusungirako mphamvu ndi kuchepetsa mpweya, komanso zimakwaniritsa zofunikira zamakampani kuti achepetse ndalama zogwirira ntchito, kupititsa patsogolo mpikisano wothamanga komanso kumanga "doko lobiriwira".
