Kuphrojekthi ye-Hainan Tongka, ukwakheka kwesistimu yasekuqaleni kuyinkimbinkimbi, nenani elikhulu leziteshi zokufinyelela kanye nenani elikhulu ledatha yebhizinisi. Ngo-2019, ngokwezidingo zamakhasimende, uhlelo lokuphathwa kwekhadi elilodwa lwenziwa lwaba ngcono, futhi ukuphathwa kwamakhadi e-IC kanye nokugadwa kokuphepha kwesilinda segesi kwahlukaniswa, ngaleyo ndlela kuthuthukisa ukwakheka kohlelo lonke nokuthuthukisa ukusebenza kahle kohlelo lonke.

Le phrojekthi ihlanganisa iziteshi zokugcwalisa ezingama-43 futhi iqaphe ukugcwaliswa kwesilinda kwezimoto ze-CNG ezingaphezu kuka-17,000 kanye nezimoto ze-LNG ezingaphezu kwe-1,000. Ixhume izinkampani zegesi ezinkulu eziyisithupha okuyiDazhong, Shennan, Xinyuan, CNOOC, Sinopec kanye neJiarun, kanye namabhange. Amakhadi e-IC angaphezu kuka-20,000 akhishiwe.
