Imiphumela Yokusebenza Yezinkampani Zokusebenzisa Igas Yini?

Kusukela kumqondo kuya kuthenga: Isisindo sokuphelele sokuphatha kwezinkampani zokusebenzisa igas

Imiphumela yokugcina iplanti yegazi ngokuphelele faka phakamisa ukupheleka kwezindlela zokusebenza ngokusebenzisa umsebenzi wokuphatha amaprojekthi—kubantu kwezifundo zokuvavanya nokufunda ngokujulile, ukuthenga amathilathi, ukwakha, ukuzimisa ukusebenza, nokukhipha. Abasayizi baphatha inzalo yezinye izindaba ngokuphatha ukuthembeka kwezinhlelo zokusebenza, izinhlelo zokuhlonipha ubudlelwane, nokuphatha ukusuka kwezinhlelo, okukhombisa ukungafani kwezinhlelo. Lokhu kubhekisa ukuthi izinhlamvu zokusebenza zizoba zikhona ngokupheleka xa kusuka kusebenza, futhi kunciphisa isivumelwano sokusebenza kwebhizinisi. Ngokuhlanganisa izinhlelo zokuchitha izigashe zomoya, ukuchitha amandla, ukuphakama, nokubuyela amasimu ayezinkampani (NGL) ngokusebenzisa izinhlelo ezihlukene, ezisemthethweni, nezinhlelo zokusebenza ezingafani noma zingahambani ngezinhlelo zokusebenza, lokhu kubhekisa ukuthi izindlela zokuthenga zizoba zikhona ngokupheleka, futhi kubhekisa ukuthi izinhlelo zokusebenza zizoba zikhona ngokupheleka.

Ukuthi indlela yokusebenzisa izinhlelo zokugcina nezinhlelo zokufaka phakamisa kuzoba kunciphisa izintonga zomprojekthi ngama-30–50%

Ukugcina ngemibiko (modularization) kusiza ekuthimeleni ngokutshintsela ukwakha kwezindawo zokufakwa ezihlukene. Imibiko yezinhlelo zokusebenza eziqinile, eziqinile kanye nezinhlelo zokuphatha amine, izitoweli zokususa amafutha ngeglycol, nezinhlelo zokuphatha amafutha—zifakwa ngokuphelele kanye nokuzivikela ngokuphelele phambi kokuthunyelwa. Lokhu kusiza ekuthimeleni kwesikhathi esifanayo sokulungisa indawo yokuqala nokufakwa kwezinhlelo zokusebenza ngaphandle kwendawo, okusiza ekupheleleni kwesikhathi sokufaka ngaphezu kwe-60% kulokho okwenziwa ngendlela yokufaka ngokuphelele (stick-built). Izindaba zokuhlalwa kwesikhathi zokusebenza zibonisa ukuthi iziprojekthi zemibiko zifika ekupheleleni yezinhlelo zokusebenza ngokuphelele ngokuphakeme kwe-47% (Energy Global, 2023), futhi izintandokazi zokuhlala kwesikhathi zokusebenza ziziphelele ngokuphakeme kwe-80%. Izinhlelo zokuvikela ezisayiziwe, izinhlelo zokuphatha izigqumashelo eziphakamile, nokuzivikela ngokuphelele kwesikhathi sokuphatha ngaphambi kokubhekana nesikhathi sokusebenza kusiza ekuphakamiseni ubukhulu bekuvikela indawo yokuqala futhi kusiza ekupheleleni kwesikhathi sokuthola imali.

Izinhlelo Zokusebenza Zokuphatha Ngokuphelele Kwiziprojekthi Zokuphatha Amasimu
