"Tikufuna kuti machitidwe akhale osavuta kugwiritsa ntchito, komanso osinthasintha, chifukwa makina odziyimira pawokha satanthauza malo okhazikika." Alan Bryant wa Occidental adakambirana za cholinga cha kampaniyo chokhazikitsa nsanja zake zodziyimira pawokha za Permian Basin pamakabati angapo a Rockwell Automation omwe amamangidwa m'fakitale.
"Tikufuna kuti machitidwe akhale osavuta kugwiritsa ntchito, komanso osinthasintha, chifukwa makina odziyimira pawokha satanthauza malo okhazikika." Alan Bryant wa Occidental adakambirana za cholinga cha kampaniyo chokhazikitsa nsanja zake zodziyimira pawokha za Permian Basin pamakabati angapo a Rockwell Automation omwe amamangidwa m'fakitale.
Kuchuluka kwa zida zakale zomwe zili ndi zowongolera zosiyanasiyana komanso zakale sikungakhale malo abwino oyambira kukhazikitsa miyezo, koma zimakupangitsani kuifuna. Mu 2000, ntchito za Occidental Petroleum ku Permian Basin zinakula ndi kugula zitsime zomwe zilipo kuchokera ku Shell, Amoco ndi ena, kuphatikizapo machitidwe awo omwe alipo.
"Mwina tinali ndi chimodzi mwa zinthu zonse zomwe zinapangidwapo, komanso machitidwe osiyanasiyana a SCADA," anatero Alan Bryant, mlangizi wamkulu wa uinjiniya wa automation, Occidental, yemwe adapereka ndi mnzake Mauricio Castillo, mlangizi wa machitidwe owongolera mafakitale, pa Msonkhano wa Mafuta ndi Gasi pa Chiwonetsero cha Automation 2019 sabata ino ku Chicago.
Occidental ili mu bizinesi yopita kumtunda. "Timaipompa kuchokera pansi, kusiyanitsa mafuta, madzi ndi gasi, ndikugulitsa," adatero Bryant. Chigwa chake cha Permian chili ndi makilomita 75,000 kumadzulo kwa Texas ndi New Mexico. "Malo omwe tikukambawa ndi makilomita 90, malo akuluakulu oti tigwiritse ntchito ndi SCADA, okhala ndi zitsime zambirimbiri," adatero.
Bryant adalowa nawo kampaniyo mu 2003, ndipo ntchito yake yoyamba inali kupanga njira yotseguka ya SCADA kuti igwirizane ndi zitsimezo. Mu 2005, gulu lake linakhazikitsa malamulo pamndandanda wa ogulitsa ovomerezeka, "koma kukhala ndi zida zakale kumatanthauzanso kuti tinali ndi anthu akale, ndipo tinkangopereka kwa ogulitsa atatu a PLC," adatero. Komabe, adakhazikitsa malamulo a zida, ma protocol ndi mapulogalamu apamwamba.
"Mu 2011, tinasankha Rockwell Automation, chifukwa ControlLogix 5000 imatha kuthandizira chilichonse papulatifomu imodzi. Zimenezi zinatithandiza kuti tikhazikitse mapulogalamu m'magawo otsika," anatero Bryant. "Zinathandiza kuti panthawiyo, tigwirizane ndi ntchito yodziyimira pawokha, ndi akatswiri 45 pansi pa manejala m'modzi. Manejala ameneyo amafuna dongosolo limodzi lothandizira."
Pa nthawi imeneyo, kampaniyo inasintha makinawo kukhala magulu awiri—limodzi lothandizira makina opangira mafuta omwe analipo kale (EOR), lina lofufuza, kuboola ndi ntchito zachilendo zotchedwa BU. Bryant anakhala gawo la EOR, Castillo ali ku BU. “EOR inali ndi bajeti yochepa pachaka yosinthira zinthu zina mwachangu, koma makamaka kusintha zinthu zikalephera,” anatero Bryant. “Tinapanga mapanelo wamba omwe titha kuwagwiritsa ntchito mwachangu kuti tikonze zinthu komanso pazitsime zatsopano pa ma skid.
"Tili ndi bokosi la CPU lokhazikika, bokosi lamagetsi, ndi mabokosi akutali a I/O a zitsime, olekanitsa ndi mayeso. Lero, tili ndi Rockwell Automation yomwe imatitumizira mapanelo athunthu, omangidwa ndi fakitale. Tikhoza kuyika mapulogalamu okhazikika ku ma CPU okhazikika ndipo tili okonzeka kuyamba."
Mu 2017, gulu la BU linkafuna kupanga njira yokhazikika yogwiritsira ntchito zinthu zatsopano komanso zachilendo. "Timakumbanso zinthu zambiri komanso zitsime zatsopano zokhala ndi mizere yoyenda ndi malo ogwirira ntchito, zomwe zili ndi zofunikira zawo," adatero Castillo. "Nthawi ndi ndalama mu bizinesi iyi—kuchedwa kwa tsiku limodzi kapena awiri kumawononga ndalama zambiri kuposa magawo ang'onoang'ono a makina ogwirira ntchito. Tikufuna kuti makina azikhala osavuta kugwiritsa ntchito, komanso osinthasintha, chifukwa makina okhazikika satanthauza malo okhazikika."
Gululo linkachita zinthu zambiri zosinthira ma panelo enaake. Linkafunika nthawi yochepa yotsogolera komanso kuthekera kosintha mochedwa. "Tikuda nkhawa ndi mtengo wonse wa umwini (TCO), osati mtengo wotsika woyambira," adatero Castillo. "Tikufunika luso losamalira, ndikuwonjezera zida, zosintha, ndi I/O mtsogolo. Ndi unyolo wodalirika woperekera zinthu."
Sitima yapamadzi yanthawi zonse imakhala ndi zitsime pamodzi ndi zolekanitsa, chotenthetsera, matanki amafuta, matanki amadzi, malo otumizira madzi, chotsukira gasi, zoyezera mpweya ndi gasi ndi mafuta, ndi mapampu, ma valve ndi zida zogwirizana nazo.
Njira yokhazikika ya BU imazindikira zofunikira zodziyimira pawokha pogwiritsa ntchito zida (PLC kapena Remote I/O); kukula kwa enclosure—yaing'ono, yaying'ono, kapena yapakatikati; mtundu (CPU ndi kukhazikitsa module); maziko/kukulitsa (kuchuluka kwa module); mtundu; ndi dzina la zinthu zomwe zili mumndandanda (kufotokozera). Zotsatira zake ndi mitundu isanu ndi iwiri ya zida zomwe zingagwirizane ndi zofunikira. "Mutha kuziyika pamodzi kuti mupeze zomwe mukufuna," adatero Castillo. "Mutha kugwiritsa ntchito mtundu woyambira kapena kupereka malo owonjezera kapena kusintha kapena kuwonjezera zida."
Anakhazikitsanso mawaya osiyanasiyana pa mitundu 11. "Zimatenga mphindi zochepa kuti waya ilumikizane ndi mawaya poyerekeza ndi maola kuti ilumikizane, ndikuwongolera bwino komanso kugwirira ntchito bwino," adatero Castillo, "Ndipo ngati pali vuto la waya, mutha kungosintha chingwe."
Akapanga sitima, ngati sitima ina ibwera, amatha kungobwereza zomwe zachitika. "Tikhoza kukhala ndi mabokosi okhazikika, omangidwa kale m'malo mopanga mapanelo apadera," adatero Castillo. "Ndipo pakapita nthawi, pamene mitundu yatsopano ndi mapurosesa akutuluka, timatha kusamukira kwa iwo kotero kuti yakale ikatha ntchito, timadziwa kale choti tiisinthe."
Akonza mapangidwe awo bwino ndi zikalata zabwino komanso kugula zinthu mosavuta. "Ndikhoza kuyimbira wogulitsa ndikumuuza kuti ndikufuna 20 mwa izi m'miyezi isanu ndi umodzi ikubwerayi," adatero Castillo. "Tili ndi zida zoti tigwiritse ntchito pamalo omanga kuti ogwira ntchito athe kulumikizana ndikuyesa chilichonse mwachangu."
Kukhala ndi zida zomwezo kulikonse kumapangitsa kuti zikhale zosavuta kuphunzitsa anthu. Ndipo, ngati atapeza kuti pali vuto ndi gawo linalake, monga block ya terminal, amatha kulisintha ndikukonza zinthu zomwe zili m'gululi.
"Kukhazikitsa miyezo yokhazikika kungagwire ntchito mumakampani aliwonse, osati mafuta ndi gasi okha," adatero Castillo. "Koma, ngati muli ndi njira 13 zochitira zinthu ndikusankha kukhazikitsa miyezo yokhazikika, musamalize ndi miyezo 14."
