Lipoti la kafukufuku wa ngozi ya mankhwala

Webusaiti yovomerezeka ya Guangxi Zhuang Autonomous Region Emergency Management Department idatulutsa Lipoti Lofufuza pa ngozi Yamoto Yaikulu ku Beihai LNG Co., LTD pa Novembara 2, 2020. Malinga ndi lipotilo, anthu 7 adamwalira, anthu 2 adavulala kwambiri komanso mwachindunji. kuwonongeka kwachuma kunali 20.293 miliyoni yuan.

Nthawi yomweyo chifukwa cha ngozi

Pakukhazikitsidwa kwa gawo lachiwiri la polojekitiyi, valavu yodzipatula imatsegulidwa, ndipo LNG (gasi wachilengedwe wonyezimira) mumayendedwe otsika akunja opatsirana amatulutsidwa pakamwa patopo, ndi kusakaniza kwa LNG atomiki misa. ndipo mpweya umatulutsa kuyaka pamene mphamvu yoyatsira ingathe.

Chifukwa chosalunjika cha ngozi

Zolakwika mavavu kudzipatula njira, injiniya chida osati mogwirizana ndi makonzedwe a chida interlock kuti kuunika ndi kuvomereza ndondomeko ndi ndondomeko ntchito, kutentha ntchito zinatsimikizira kuti kusakwanira, osakwanira chitetezo chiopsezo chikumbumtima ndi kulamulira, "eni mabizinesi ang'onoang'ono mgwirizano waukulu" kupanga gulu njira kupanga kukhazikitsidwa kwa udindo woyang'anira kasamalidwe kotetezeka sikufika pamalo omwe adasankhidwa, oyang'anira makontrakitala safika pamalo omwe adasankhidwa, ndi zina zotero.

Lipoti lofufuza linanena

M'mawa wa tsikulo, injiniya wa zida Lai Xiaolin sanachite zinthu zingapo monga kuwunika kotsatira ndikutsimikizira tikiti yolumikizira chida, koma adalowa m'malo opangira mainjiniya ndikugwira ntchito yekha popanda kuyang'aniridwa ndi akatswiri ena a zida.

Pa 11:44 mphindi ndi masekondi 48, Lai Xiaolin adagwiritsa ntchito makina a SIS kuti atseke mwamphamvu valavu 0301-XV-2001.Nthawi yomweyo, vavu 0301-XV-2001 idatsegulidwa ndipo LNG idayamba kupopera.Pa 11:45 mphindi 00 masekondi, valavu imatsegulidwa kwathunthu.Pafupifupi masekondi a 10 pambuyo pa jekeseni wa LNG, moto unayamba pa nsanja kutsogolo kwa thanki yosungirako TK-02.Panali anthu 8, kuphatikizapo Liang, pa nsanja kutsogolo kwa thanki yosungirako TK-02 ndi munthu mmodzi, kuphatikizapo Tian, ​​pamwamba pa thanki pamene LNG inayaka moto.

Lipotilo linatero

Pangozi iyi, sinopec Zhongyuan Petroleum Bureau Natural Gas Technology service Center, Beihai LNG Company, Sinopec Tenth Construction, Henan Hongyu, Sichuan Yitong, Sinopec Guangzhou Engineering, Qingdao Transocean ali ndi zinthu zosaloledwa komanso zosaloledwa.Pakati pawo, Natural Gas Technical Service Center ya Zhongyuan Petroleum Bureau ya Sinopec idaphwanya malamulo oyendetsera zida zotchingira chitetezo ndipo sanatsatire mosamalitsa njira yovomerezeka yolumikizira zida molingana ndi malamulo.Katswiri wazopanga zida Lai Xiaolin adachita ntchito yolumikizirana mokakamiza isanavomerezedwe tikiti yolumikizirana ndipo panalibe wowasamalira.

Gulu la akatswiri a mankhwala a HSE a ntchito inayake anakambirana mwapadera za ngoziyo.Nditawona zokamba za katswiri aliyense, ndinaphunzira zambiri.Nazi kusanthula ndi chidule:
1.Ngoziyi idachitika popanda kudzipatula koyenera kwa magwero amphamvu owopsa.Panali zovuta mumalingaliro a ESD shutdown system mu SIS system, ndipo kupopera kwa mbale kwakhungu sikunathe kuchitapo kanthu.Chofunika kwambiri, musakhulupirire "dongosolo" kwambiri, dongosolo lililonse likhoza kulephera.LOTOTO(Lockout/tagout/ test)ndi kulumikizana kwakuthupi ngati kuli kotheka.Chitsimikizo ndi chivomerezo chidzapangidwa molingana ndi ulamuliro ndi udindo wa ogwira ntchito pamagulu onse.

2.Sanakhale ndi ndondomeko yovomerezeka yogwira ntchito yoopsa, ndipo sanayese kuyesa chitetezo chisanachitike (JSA) chisanayambe ntchito.Malinga ndi kuunika kosamalitsa ndi njira zovomerezeka zogwirira ntchito zoopsa, wopempha ndi woyang'anira ayenera kutsatira mosamalitsa kuwunika kwachitetezo musanachite opaleshoniyo, ndipo chivomerezocho chiyenera kupita pamalowo kuti chitsimikizidwe chisanavomerezedwe.

3.Lipoti la kafukufuku wa ngozi likuwoneka kuti ndi losamala kwambiri, ndipo ngakhale mfundo ndi mphindi ndizomveka bwino: pa 11:20, mbali yomwe ili pafupi ndi thanki yadulidwa, ndipo pa 11:40, n'chifukwa chiyani mumalimbikitsa kugwiritsa ntchito chida. tikiti yantchito yolumikizana?Chachiwiri, valavu iyi iyenera kukhala valavu yotsika yamadzimadzi.Kodi chinatsekedwa liti ndipo chinatsekedwa bwanji?Osati anthu ambiri sanamvetse valavu yotsekedwa kuti alimbikitse injiniya kuti atseke valavu kachiwiri.Mafunso ambiri okhudza zambiri, koma osayang'ana, palibe ulusi.Ndizovuta kumvetsa.
