Ndi njira iyi, timasunga kuchuluka kwa vacuum pansi pa 10⁻³ mbar komwe kuli kofunikira kwambiri. Mumapeza kutsika pang'ono kwa kutentha, ngakhale zaka zambiri mtsogolo. Kuphatikiza apo, kudalirika kwa ntchito za LNG zopitilira komanso maukonde akuluakulu a gasi kumawonjezeka kwambiri.
Pa mapulojekiti a EPC, izi zikutanthauza kuti kukonza sikuchedwa. Pakapita nthawi, ntchito yonse imayenda bwino ndipo imawononga ndalama zochepa.
