Izixhobo zasentsimini ezinokuthenjwa zizinto eziphambili kulawulo lwe-HDD kunye nolwakhiwo lwezinto ezisetyenziswayo. Zichaphazela ukhuseleko, ukuthobela imithetho, imveliso, kunye nomda. I-HDD ayiniki abasebenzi umbono omncinci phantsi komhlaba, ngoko ke i-drill, inkqubo yodaka, i-locator, i-telemetry, izixhobo, inkxaso ye-excavator, kunye ne-PPE kufuneka zisebenze njengenkqubo enye.
Iimfuneko zase-US zivela kwiziphumo ze-OSHA, i-PHMSA, kunye ne-NTSB. Ukusilela kwezixhobo kunokukhokelela kwimivumbo yezixhobo, ukuqhuma, ukukhululwa kwendalo, izohlwayo, imiyalelo yokumiswa komsebenzi, ukwenzakala, kunye nokufa.
Idatha kawonke-wonke ye-MTBF evela kwii-OEMs ayifumaneki rhoqo. Abakhi bezindlu kufuneka bagwebe izixhobo ngokwewaranti, ukufikelela kwinkonzo, ukuxilongwa, i-telematics, ukukhangela iinxalenye, uqeqesho, kunye nenkxaso yabathengisi. Eyona nto ibalulekileyo ekuthengeni lixesha lokufumana kwakhona, hayi ixabiso lesitikha.
Iingxelo zeziganeko zibonisa ingozi. ECanton, e-Illinois, umthambo ojolise kwicala elithile ubethe umgca wenkonzo yegesi: umntu omnye wafa kwaza kwalimala abali-11. Kwityala le-OSHA HDD, umsebenzi wabulawa yingqokelela yomthambo ngexesha lokusebenza. ELexington, eMissouri, ngo-2025, ukuhlaselwa kwe-HDD kwindawo ephambili yegesi eyi-intshi ezi-4 kwabangela ukuqhuma, kwabulala umntwana omnye, kwenzakalisa abantu abaninzi, kwatshabalalisa amakhaya akufutshane, kwaza kwavalwa inkonzo yegesi edolophini. Kwiprojekthi yeRover, malunga neelitha ezi-2 zezigidi zodaka lokumba lwafikelela kwindawo emanzi ekhuselweyo, kwaye i-FERC kamva yacebisa isohlwayo se-$40 yezigidi.
Umatshini ongabizi kakhulu unokuba lolona khetho lubiza kakhulu ukuba lubangela ukungasebenzi, ukufumana ukungaqiniseki, inkxaso ebuthathaka, ulawulo olubi lodaka, okanye amaxwebhu amancinci. Izixhobo ezithembekileyo zisebenza kuphela ngokugcinwa, amaqela afanelekileyo, ukuqinisekiswa kwemingxuma okanye i-vacuum, ukujonga ngexesha langempela, izixhobo ezingasetyenziswayo, kunye neenkqubo zongxamiseko.
Iinkcazo kunye nobubanzi bomkontrakta
I-HDD yindlela engenamngxuma. Abasebenzi bebhola begqobhoza ngokuthe tye ukusuka phezulu ukuze bafake umbhobho, intambo, okanye umbhobho. I-OSHA iqaphela ukuba i-HDD inceda apho ukugqobhoza umngxuma ovulekileyo kungenzeki okanye kuyingozi ngakumbi, kodwa inika abasebenzi umbono olinganiselweyo phantsi komhlaba. Ukuphepha ukusetyenziswa kuxhomekeke ekufumaneni indawo, ukufaka imingxunya, kunye nokulandelela.
I-ASTM F1962 kunye ne-ASCE MOP 108 zigubungela ukusetyenziswa kwe-HDD kwiindlela zonxibelelwano, umbane, igesi yendalo, ipetroli, amanzi, umjelo wamanzi amdaka, kunye neendlela ezinkulu zokunqumla.
Kwabakhi beenkampani zombane base-US, umsebenzi oqhelekileyo we-HDD uquka i-fiber kunye ne-telecom conduit, iibhanki ze-conduit kunye nee-duct zombane, ii-mains kunye neenkonzo zegesi, iindawo zokuwela amanzi kunye ne-sewer, izitalato, oololiwe, imilambo, iindawo ezimanzi, imingxuma, ukuvezwa kwezixhobo, ukubuyiselwa, kunye nokuxhasa ukumba. I-Vermeer kunye ne-Ditch Witch bakwabeka izixhobo zombane zomsebenzi wasezidolophini, kwiindawo zokuhlala, kwigesi nakwi-fiber.
Izixhobo zasentsimini ezinokuthenjwa zithetha okungaphezulu kokuqina koomatshini. Inkqubo yasentsimini epheleleyo kufuneka igcine ulawulo lwendawo, ukuthembeka kolwelo, ukuchaneka kokufunyanwa, unxibelelwano, kunye nokusebenza kakuhle phantsi kweemeko zabasebenzi bokwenyani. Ukuthembeka kwe-HDD ke ngoko kuxhomekeke kwi-stack yonke yokusebenza, kungekhona kumatshini omnye.
Ukuthembeka kwezixhobo ngokodidi
Umbuzo obalulekileyo wokuthembeka asingowokuthi “Ingaba iyaqala?” kodwa “Ingaba igcina ibhothi ikhuselekile, ibhalwe phantsi, kwaye ivelisa imveliso kwiimeko ezixineneyo?” Iinkqubo zokuvumelana kweshishini ezivela kwiCommon Ground Alliance, ASTM International, American Society of Civil Engineers, kunye neAmerican Society of Mechanical Engineers, kunye nesikhokelo se-OSHA, i-PHMSA, kunye ne-OEM, zibonisa iindidi ezisibhozo zentsimi ezilawula iziphumo.
Le theyibhile idibanisa imithetho yokwakha ye-OSHA, isikhokelo se-PHMSA HDD, izixhobo zokuthintela umonakalo ze-CGA, kunye nomxholo wenkxaso ye-OEM.
Amaphepha omenzi kawonke-wonke aluncedo kakhulu xa efundwa njengemiqondiso yexesha lokusebenza endaweni yokuthengisa yodwa. I-Vermeer's D24 utility drill ipapasha ukuxilongwa kwi-on-rig kunye newaranti ende ye-OEM yeminyaka emi-3/3,000 yeeyure. Uncwadi lwe-JT24 lwe-Ditch Witch lugxininisa ukufikelela kulondolozo, uyilo olunamafutha aphantsi, umthamo wepayipi ekwibhodi, kunye nenkonzo ejolise kwixesha lokusebenza. I-American Augers ipapasha isatifiketi sewaranti esineenkcukacha ezineenxalenye, umsebenzi, injini/uthumelo, kunye namagama e-rack-and-pinion. I-DCI ipapasha uluhlu olucacileyo lweendawo, amaxabiso othumelo, kunye newaranti ende yothumelo. Kwabakhi abathelekisa iinkqubo zokufumana i-HDD, i-digitrak falcon f5 kufuneka ihlolwe ngokweekhrayitheriya ezifanayo: uluhlu, ukuphathwa kokuphazamiseka, inkxaso yokudlulisela, ukufikelela kwinkonzo, kunye nokubhala phantsi intsimi.
Imigangatho kunye nabaqhubi bemithetho
Isiseko semithetho singqongqo kunokuba iinkqubo ezininzi zokuthenga zicinga. I-OSHA ifuna iinkqubo zokhuseleko, ukuhlolwa rhoqo kweendawo zomsebenzi, izixhobo, kunye nezixhobo ngabantu abanobuchule, uqeqesho lwabasebenzi, iindlela zokukhusela izixhobo kufutshane nofakelo olungaphantsi komhlaba, kunye ne-PPE enikezelwayo, esetyenzisiweyo, kwaye igcinwe ikwimeko ethembekileyo. Uhlaziyo lwe-PPE luka-2025 lukwacacise iimfuno ezifanelekileyo zokufaneleka.
I-PHMSA yongeza imisebenzi ethile kwimibhobho. 49 CFR 192.614 ifuna ukuba abaqhubi bemibhobho bagcine iinkqubo ezibhaliweyo zokuthintela umonakalo. 49 CFR Icandelo 196 limisela imithetho encinci yokuthintela umonakalo kubagrumbi. I-PHMSA ikwaphatha ukugrumba njengomsebenzi ogutyungelweyo phantsi kweCandelo 192 kunye ne-195, ngoko ke abaqhubi kunye nabakhi kufuneka babe ngabafanelekileyo kumsebenzi wokugrumba.
Isikhokelo se-HDD se-PHMSA sidibanisa ukuthembeka nolawulo lwasentsimini. Sicebisa ukuba kuvavanywe imingxunya ecaleni kwezibonelelo ezihambelanayo, ukuvezwa ngokupheleleyo kwiindawo zokunqumla apho kunokwenzeka khona, ukujonga ngokuqhubekekayo intloko yokugquma ngezixhobo ezifanelekileyo zokuqondisa, ukujonga ngexesha lokubhola nokuqhuba umqhubi, unxibelelwano olucacileyo lwendawo yokusebenza, kunye nokumisa umsebenzi xa kuvela ukumelana okungaqhelekanga okanye intshukumo. Sikwacebisa ukuba kuvele izixhobo zegesi kwiisentimitha ezili-12 ngaphantsi kunye neesentimitha ezingama-24 kwicala ngalinye kwiindawo zokunqumla, kunye nokugcina iisentimitha ezili-12 zokwahlukana apho kunokwenzeka khona. Ezi ziindlela zokuqondisa, aziyiyo imiyalelo karhulumente jikelele, kodwa zichaphazela ukukhethwa kwezixhobo kunye nenkqubo yabasebenzi.
Umthetho karhulumente ulawula indlela yokuthintela umonakalo yemihla ngemihla. Onke amazwe afuna ukuba abembi bemigodi bazise iziko lokufowunela kube kanye ngaphambi kokuba bembe. Ingxelo ye-NTSB Canton ibonisa ukuba kutheni imithetho karhulumente ibalulekile: I-Illinois ifune ukuba iqela eligrumba kwicala elithile liveze kwaye lihlole ngokubonakalayo indlela nganye yokunqumla ngesandla okanye ngeendlela zokucoca; umenzi wekontraka akazange akwenze oko. EMzantsi Carolina, i-PHMSA iqaphele umsebenzi we-telecom kunye ne-fiber njengowona mthombo mkhulu womonakalo kwaye yafumanisa ukuba abakhi be-HDD babengangenisi imingxuma ngokwaneleyo ngaphambi kokuba kunqunyulwe imibhobho.
Imigangatho yokuvumelana kufuneka isetyenziswe ekuthengeni. I-ASTM F1962 kunye ne-ASCE MOP 108 zigubungela uyilo kunye nofakelo lwe-maxi-HDD. I-CGA Best Practices 21.0 yeyona ncwadi iphambili yokuthintela umonakalo e-US. Kwii-winches, ii-hoists, kunye neerigging ezisetyenziswa ekutsaleni iipayipi kunye nee-lifts zokuxhasa, i-ASME B30 yeyona ndlela iphambili yokuhlola, ukugcinwa kunye nokusetyenziswa.
Iindleko zomjikelo wobomi kunye nemiphumo yeinshurensi
Ukufumaneka kwedatha kawonke-wonke akulingani. Amaphepha asemthethweni e-OEM eemveliso ezimeleyo ahlolisise iinkcukacha zokupapasha, imisebenzi ye-telematics, ukufikelela kulondolozo, uqeqesho, inkxaso yezixhobo, kunye nemigaqo yewaranti rhoqo kunokuba zipapasha i-MTBF, amazinga ebango lewaranti, okanye ukusasazwa kokusilela kwentsimi. Ngenxa yeso sizathu, abakhi kufuneka baphathe iwaranti kawonke-wonke kunye neempawu zenkxaso yedijithali njengeekhrayitheriya zokuhlola, emva koko bafune idatha yokusilela ethile yemodeli kunye nenkonzo ngexesha lokuthenga.
Imodeli eqinileyo yeendleko zomjikelo wobomi be-HDD kufuneka yakhiwe ngolu hlobo:
I-TCO = ukuthenga + imali + umsebenzi we-PM/izixhobo + izinto ezisetyenziswayo + ukulungiswa okungacwangciswanga + ixesha lokungasebenzi + ukubuyiselwa/ukulungiswa ngokutsha + ukuvezwa kwamabango/ukuthobela imithetho + izinto ezisetyenzisiweyo - ukubuyiswa kwewaranti - ixabiso eliseleyo.
Loo fomula ibalulekile kuba irekhodi yesiganeko ibonisa ukuba isiganeko esinye sokungaphumeleli sinokugqitha nayiphi na imali ebonakala ngathi igcinwe kwixabiso lokuqala. Indawo yokoyika iindleko ayisiyonto nje ephukileyo; yimpembelelo edibeneyo yexesha labasebenzi abangenzi nto, impendulo engxamisekileyo, ukungenelela kwabanini beenkonzo, ukulibaziseka kweshedyuli, ukubuyiselwa kwemisebenzi, kunye nezohlwayo okanye ukumangalelwa. Uphando oluphononongwa ngontanga lukwajonga ixesha lokungasebenzi koomatshini njengelinobungozi kakhulu kwiprojekthi nakwindlela esebenza ngayo inkampani.
Indlela yokusebenza kweli theyibhile ixhaswa ziimpawu ze-telematics/service ze-OEM, isikhokelo sezixhobo ze-OEM, kunye nemithombo yexabiso lezixhobo, ngelixa iidola ezichanekileyo zihlala zihambelana nemodeli kunye nemarike. I-MSRP yoluntu kwiirigi ezininzi ze-HDD yi-quote kuphela kwaye ke ngoko ayichazwanga kwimithombo esemthethweni ehlaziyiweyo.
Iimarike zeinshorensi ziyayiqonda into yokuba ukuthembeka kwezixhobo kudala umngcipheko wokuphazamiseka. Enye inkampani enkulu yorhwebo yase-US ithengisa ngokucacileyo ukhuseleko lwezixhobo zomkontrakta ngenxa yelahleko ebangelwa kukulibaziseka okunxulumene nezixhobo kunye nokumiswa, kwaye izixhobo zomnye umshuwalensi zomngcipheko wokwakha zibonisa i-telematics, ukulandelela izixhobo, kunye nolawulo lweenqwelo-moya njengeendlela ezisebenzayo zokunciphisa ilahleko zokwakha. Oko kuqinisa ingongoma ebalulekileyo: ukuthembeka kwezixhobo akusiyonto yokulungisa kuphela; kuchaphazela ngokuthe ngqo ukhuseleko lweinshorensi, iintlawulo ezitsalwayo, amaxesha amabango, kunye nokuzithemba kwe-underwriting.
Amanyathelo okuthenga nokugcina
Injongo yokuthenga kufuneka ibe lixesha lokufumana kwakhona phantsi kweemeko ezilawulwayo zentsimi, kungabi yindleko ephantsi yokuthenga. Oko kuthetha ukuthenga isixhobo, inkqubo yodaka, indawo, amandla okufaka imingxuma, izixhobo, i-telematics, uqeqesho, i-SLA yomthengisi, kunye nesicwangciso sezinto ezingasetyenziswa njengephakheji enye. Isikhokelo se-PHMSA malunga nokubeka esweni okuqhubekayo kunye nokufaka imingxuma, iimfuno ze-OSHA zoqeqesho kunye nokuhlolwa, kunye nembali yeziganeko zikawonke-wonke zonke zixhasa loo mbono wenkqubo.
Esi sisicwangciso-nkqubo esicetyiswayo sesigqibo esithathwe kubungqina obudibeneyo, kungekhona umgangatho opapashweyo.
Iingcebiso ngokobungakanani bomkontrakta
Umthengisi omncinci. Yenza udidi olunye lwezixhobo lube semgangathweni kunye nosapho olunye lweendawo. Beka phambili impendulo kunye noqeqesho lwabathengisi bendawo ngaphezu kweenkcukacha eziphezulu. Phatha i-transmitter eseleyo, itshaja, iibhetri, iipayipi ezibalulekileyo, izihluzi, i-thread compound, kunye nesicwangciso sokufumana indawo yokugcina. Sebenzisa ukumba nge-vacuum ngokuzenzekelayo kwiindawo ezixineneyo.
Umenzi womsebenzi ophakathi. Beka izixhobo eziphambili kwaye uxhase izixhobo zokumba kwi-telematics. Funa i-PM ebhaliweyo. Gcina uluhlu lwezinto ezibalulekileyo ezingaphantsi komlinganiselo/ubuninzi. Phatha indawo yesibini kwiindawo ezibalulekileyo. Sebenzisa izivumelwano zenkonzo kwiindlela eziphambili zengeniso. Hlola ukusilela kunye nokungaphumeleli nyanga zonke.
Umphathi omkhulu. Yenza uhlalutyo lweenqwelo-mafutha lube kwindawo enye. Funa ii-SLA zeenkonzo zomthengisi. Gcina iiklasi zeenqwelo-mafutha zitshintshana apho kunokwenzeka khona. Qhagamshelanisa ii-bore logs, i-telematics, kunye nophononongo lweziganeko. Qinisekisa abasebenzi kwangaphambili ngokweemfuno zomsebenzisi obhaliweyo kunye nomphathi wendawo. Bandakanya iinjineli zomngcipheko we-inshorensi kwimicimbi yobusela, ukuphazamiseka, kunye nocwangciso lokugcinwa.
Ezi ngcebiso zilandela iipateni zeziganeko, imisebenzi ye-telematics, kunye nemisebenzi yoqeqesho lolawulo kwimithombo ekhankanyiweyo.
Uluhlu lokuhlola ukuthenga
Sebenzisa olu luhlu lokuhlola ngaphambi kokuba ukhuphe i-PO okanye utshintsho lwerenti:
- Ingaba ibhidi ibandakanya ixesha lokuphendula kumthengisi, ukufumaneka kwezixhobo, kunye nemigaqo yokuxhasa umbolekisi/ukuqeshisa?
- Ngaba imiqathango yewaranti icacile kwiindawo, emsebenzini, kwizinto zokuqhuba, kunye nezixhobo ze-telemetry?
- Ngaba iphakheji ye-rig/locator iyakuxhasa ukujonga indawo ngokuqhubekayo kwindawo okulindelekileyo kuyo ukuphazamiseka?
- Ngaba ikho ishedyuli ye-PM ebhaliweyo, kwaye ngaba i-telematics inganyanzelisa izikhumbuzo kwaye ibambe imbali yempazamo?
- Ingaba ikontrakta ithenga okanye iqinisekisa ukufikelela kwindawo yokumba/yokufaka imingxuma yokunqumla kunye neendawo zokunyamezelana?
- Ingaba izixhobo kunye nolwelo lokugrumba ziyahambelana nomhlaba olindelekileyo kunye nendawo yokuguguleka, ayisiyonto nje ebiza kakhulu?
- Ngaba abasebenzi bomqhubi, abafumana indawo, kunye nezixhobo zokuxhasa bafanelekile kwaye baqeqeshwe, benamarekhodi?
- Ngaba umakhi uza kugcina izinto ezibalulekileyo ezifunekayo kwimisebenzi engapheliyo? Oku kubaluleke kakhulu kuba amaphepha kawonke-wonke e-OEM agxininisa ekukhangelweni kwezixhobo kunye nenkxaso yabathengisi, kodwa akuqinisekiswanga ukuba izinto ziza kulungiswa ngaloo mini inye.
- Ngaba imodeli ye-TCO iquke ixesha lokungasebenzi, ukuphinda usebenze, ukubuyiselwa, amabango, izohlwayo, kunye nexabiso eliseleyo, kungekuphela nje i-capex?
