Na lākou ke kuleana no nā hana hāpai āpau ma luna o ke kahua a me nā hana hoʻoili mea ma waena o ke kahua a me nā moku kākoʻo. ʻAʻole e like me nā crane ma ka ʻāina,nā crane paepae ma wahohe mau koi kiʻekiʻe loa no ka palekana, ka hilinaʻi, ka mālama ʻana, ke kū'ē ʻana i ka makani, a me ke kū'ē ʻana i ka pala. ʻO ke koho ʻana i ka crane kūpono no nā pono hana o ka paepae he mea nui ia no ka palekana a me ka waiwai hoʻokele waiwai.
I. Nā Pilikia Kaiapuni Kūikawā oMa waho o ka ʻāinaNā Paepae ʻAila
He ʻino loa ke kaiapuni kai kahi e hana ai nā kahua aila ma waho. Pono ke koho ʻana i nā crane e ʻike mua i nā pilikia i kau ʻia e nā kumu kaiapuni e hiki mai ana:
ʻO ka paʻakai nui a me ka palaho nui: ʻO ka nui o ka paʻakai i loko o ke kai e hōʻino loa i nā hale metala. Pono ke koho ʻana e hōʻoia i ka hoʻohana ʻana o ka crane i ka hoʻolālā anti-corrosion ma ke ʻano moana, e like me nā uhi anti-corrosion i hōʻoia ʻia e ISO 12944 C5-M a me nā ʻāpana kila kila me ke kūpaʻa wai paʻakai. ʻO nā mea hana a me ka hoʻolālā anti-corrosion nā ʻōkuhi loea koʻikoʻi i ke koho ʻana i ka crane no nā hale hana petroleum ma waho.
Nā makani ikaika a me nā nalu: ʻIke nā kahua kai i nā neʻe hoʻomau a me nā neʻe ʻana ma lalo o ka makani a me ka hana a ka nalu. ʻOi aku ke kiʻekiʻe o nā mea palekana i hoʻopili ʻia i nā crane kahua kai ma mua o nā crane ma ka ʻāina. Wahi a nā lula pili o ka International Maritime Organization (IMO), ma muli o ke koʻikoʻi o ke kaiapuni kai, ʻo ka dute factor Fd no nā mea āpau.pioKāne ʻo Kahakaisa me nā lako hana hāpai ʻē aʻe i hoʻohana ʻia i nā kūlana kai ākea/kahua ʻē aʻe ua wehewehe ʻia ʻo 1.20. Pono e koho ʻia nā crane me ke kūpaʻa maikaʻi i ka makani a me ka nalu, e like me nā mea i lako me nā mea anti-overturning.
Nā koi pale pahū: He mau wahi pilikia kiʻekiʻe nā kahua aila ma waho o ke kai me nā mea lapalapa a pahū. Pono nā ʻōnaehana uila a me nā ʻāpana hydraulic o nā cranes i ka hana pale pahū. Pono ke koho ʻana e hōʻoia i ka hoʻokō ʻana o ka huahana i nā palapala hōʻoia pale pahū kūpono, e like me ke kūlana pale pahū aupuni o Kina (GB3836) a i ʻole nā kūlana pale pahū honua.
Nā palena o ka hakahaka: He palena ka wahi o nā papahele paepae kai a me nā lako i hoʻonohonoho pono ʻia. Pono ka crane e hoʻokō i ka uhi hana kiʻekiʻe loa i loko o ka wahi hoʻonohonoho palena ʻia, e hoʻolilo ana i ka hoʻolālā paʻa i mea nui e noʻonoʻo ai i ke koho ʻana.
II. Nā Kūlana Honua a me ka Palapala Hōʻoia: ʻO ka Compliance Foundation no ke Koho ʻana
Pono ke koho ʻana o nā cranes no nā kahua ʻaila ma waho e kūlike me nā kūlana hoʻolālā a me nā hana hana i ʻae ʻia ma ka honua. ʻO ka mea i mana nui ʻia ma waena o kēia mau mea ʻo API Spec 2C (Specification for Offshore Pedestal-Crane i kau ʻias). Hoʻopuka ʻia e ka American Petroleum Institute (API), hāʻawi kēia kūlana i nā koi kikoʻī no ka hoʻolālā, ke kūkulu ʻana, a me ka hoʻāʻo ʻana i nā cranes pedestal-mounted offshore. Ho'ākāka ʻo API Spec 2C i kahi crane offshore ma ke ʻano he crane hāpai a me ka slewing i kau ʻia ma ka pedestal i hoʻohana ʻia e hoʻoili i nā mea a i ʻole nā limahana ma waena o nā moku, nā barges, a me nā hale, me nā noi maʻamau e pili ana i ka ʻimi ʻana a me ka hana ʻana i ka ʻaila a me ke kinoea ma waho, nā hana papahele moku, a me nā hana moku crane.
Eia kekahi, ʻo SY/T 10003-2016 "Specification for Offshore Platform Cranes" kahi kumu koʻikoʻi no ka hoʻolālā a me ke koho ʻana o ka crane ma nā kahua kai Kina, e uhi ana i nā mea āpau mai ke koho ʻana i ka hoʻolālā a me ke kauoha ʻana i ka hoʻonohonoho ʻana a hiki i ka hana o kēlā me kēia lā, ka mālama ʻana, a me ka nānā ʻana. ʻO EN 13852-1:2013 ke kūlana maʻamau o ʻEulopa no nā crane kai.
Ma ke ʻano o ka palapala hōʻoia, ʻo nā crane paepae aila ma waho e koi pinepine i ka ʻae ʻia mai nā hui hoʻonohonoho nui e like me ABS (American Bureau of Shipping), CCS (China Classification Society), BV (Bureau Veritas), a me DNV (Det Norske Veritas). Pono nā mea kūʻai aku e noi i nā palapala hōʻoia piha mai nā mea hoʻolako i ka wā o ke kaʻina koho e hōʻoia i ka mālama ʻana i nā kikoʻī pili.
III. Nā ʻAno Kūkulu Nui a me kā lākou mau hiʻohiʻona pili
Hiki ke hoʻokaʻawale nui ʻia nā cranes paepae ma waho i loko opūʻulu telescopic, pūʻulu puka makani, a mepuʻupuʻu kuʻekuʻe limanā ʻano e pili ana i ke ʻano kūkulu. Loaʻa i kēlā me kēia ʻano kona mau pono ponoʻī a me nā noi kūpono.
1. Crane Boom Telescopic
Loaʻa i nā crane boom telescopic nā boom telescopic ʻano pahu multi-section e hoʻolōʻihi i nā pae i ka wā hana a huki hou i ka wā e mālama ʻia ai. ʻO kā lākou mau pono nui:
- ʻO ka radius hana maʻalahi a hiki ke hoʻololi ʻia: Hiki ke hāpai i nā hana ma nā radii like ʻole ma kahi ākea
- ʻO ke kelekope laina pololei pololei: Kūpono no ka hāpai ʻana i nā hana e pono ai ke kūlana pololei
- Kiʻekiʻe hāpai kiʻekiʻe: He mea maikaʻi no nā hiʻohiʻona e pono ai nā kiʻekiʻe hāpai nui
Nā hiʻohiʻona kūpono: Ke kau ʻana o nā lako ma nā kahua aila ma waho, ke pani ʻana i nā ʻāpana nui, nā hana wellhead, a me nā hana ʻē aʻe e pono ai nā radii hana nui a me nā kiʻekiʻe hāpai. Hāʻawi nā cranes telescopic boom offshore o MAXTECH i nā hiki ke hāpai mai 1 tone a 100 tone, me ka lōʻihi o ka boom a hiki i 30 mika a i ʻole 47.5 mika.
2. Crane Boom Lattice
Hoʻohana nā crane boom lattice i kahi boom i hoʻonohonoho ʻia me ka lattice, e hōʻike ana i ke kaumaha ponoʻī māmā a me ka paʻakikī maikaʻi, me nā pono i ka hāpai ʻana i nā tona nui. Hoʻokomo nā hiʻohiʻona maʻamau i nā kikoʻī like ʻole mai 20 tons a 80 tons.
Nā hiʻohiʻona kūpono: Ka hāpai kaumaha ʻana i nā mea me ke tona nui, ke kau ʻana i nā lako nui, a me nā hana ʻē aʻe me nā koi hiki ke hāpai kiʻekiʻe loa.
3. Knuckle Boom Crane
Loaʻa i nā knuckle boom cranes nā lima articulated he nui e hiki ke pelu a hoʻolōʻihi e like me nā hono. ʻO kā lākou mau pono nui:
- ʻAno liʻiliʻi: Noho liʻiliʻi i kahi liʻiliʻi ke pelu ʻia, kūpono no nā kahua me ka palena palena o ka papahele
- Hana maʻalahi: Hiki ke kau pololei i nā ukana a puni nā pilikia a ma nā wahi paʻa
- Hoʻonui i ka lewa: Hāʻawi i nā pono koʻikoʻi i nā wahi kahua waho i kaupalena ʻia i ka lewa
Nā hiʻohiʻona kūpono: Ka hoʻolako ʻana i nā mea o kēlā me kēia lā, ka mālama ʻana i nā lako, ka hāpai ʻana i nā limahana, a me nā hana ʻē aʻe e pono ai ka hoʻokele maʻalahi. Wahi a ka noiʻi mākeke, manaʻo ʻia nā knuckle boom cranes e hopu i ka hapa nui loa o ka mākeke crane offshore honua, i hoʻokele ʻia e kā lākou hoʻolālā liʻiliʻi, ka neʻe articulated maʻalahi, a me ka mana hana kiʻekiʻe ma nā wahi kai paʻa.
IV. Nā Palena Koho Koʻikoʻi: Hoʻohālikelike Pololei ma muli o nā Kūlana Hana
1. Ka hiki ke hāpai a me ka Radius Hana
Hoʻoholo ʻia ka hiki ke hāpai o kahi crane e ka hui pū ʻana o ka hiki ke hāpai i helu ʻia a me ka radius hana - ʻo ka nui o ka radius hana, ʻo ka liʻiliʻi o ka hiki ke hāpai i helu ʻia. Pono ke koho e hoʻoholo i ka hiki ke hāpai nui loa a me ka radius hana nui loa e pili ana i nā pono hana maoli o ka paepae. Hāʻawi nā crane ma waho o MAXTECH i nā hiki ke hāpai mai 5 tons a i 140 tons, me nā lōʻihi boom mai 5 mika a 47.5 mika.
2. Ke Kiʻekiʻe o ka Hāpai ʻana
Ma muli o ke kiʻekiʻe o ke kahua, ke kiʻekiʻe o ka hoʻouka ukana, a me nā koi maoli o nā hana hāpai. Pono e hōʻoia ʻia e hiki i ka crane ke hāʻawi i ke kiʻekiʻe hāpai kūpono ʻoiai ma ka radius hana kiʻekiʻe loa.
3. Kaʻapuni Hana a me ka Ikaika
He ʻokoʻa loa nā pōʻaiapuni hana o nā kahua like ʻole. No nā hana haʻahaʻa alapine (pinepine) a haʻahaʻa ka ikaika (e like me ka mālama ʻana i nā pilikia, ka hāpai ʻana i nā mea i kekahi manawa), hiki ke koho ʻia nā hoʻonohonoho māmā a haʻahaʻa ka mana. No nā hana alapine kiʻekiʻe a kiʻekiʻe ka ikaika (e like me ka hoʻolako ʻana i nā mea i kēlā me kēia lā, ka hāpai pinepine ʻana i nā lako), pono nā hiʻohiʻona me ka ikaika kūkulu kiʻekiʻe a me nā ʻōnaehana mana paʻa.
4. ʻŌnaehana Mana
Hiki ke hoʻokaʻawale ʻia i loko o ka diesel-hydraulic a me ka electric-hydraulic e pili ana i ka ʻōnaehana mana. Hāʻawi nā kaʻa diesel-hydraulic i ke kūʻokoʻa ikaika a ʻaʻole hilinaʻi i ka pūnaewele mana o ke kahua; hana mālie nā kaʻa uila-hydraulic, hana ʻole i nā hoʻokuʻu ʻana, a he haʻahaʻa ka hoʻohana ʻana i ka ikehu. Pono ke koho ʻana e pili ana i nā kūlana lako mana o ke kahua a me nā koi o ke kaiapuni.
5. Nā helu pale pahū a me ka pale ʻana i ka palaho
He mau wahi pilikia kiʻekiʻe nā kahua aila ma waho o ke kai, a pono i nā crane ke loaʻa ka palapala hōʻoia pale pahū (e like me ke kūlike me GB3836 a i ʻole nā kūlana pale pahū honua) a me ka hiki ke pale i ka palaho ma ke kai (e like me ka palapala hōʻoia ISO 12944 C5-M). ʻO ka maʻamau, koi ʻia nā helu palekana ʻōnaehana uila IP66 a i ʻole IP68.
6. Nā ʻōnaehana palekana a me nā pilikia
Pono nā crane paepae ma waho o ke kai e hoʻolako me nā ʻōnaehana palekana piha, me ka kaupalena ʻole ʻia i:
- ʻŌnaehana pale kaumaha (manual/akomi)
- Mea hana pale-hoʻohuli
- ʻŌnaehana hoʻokuʻu pilikia
- Ka palekana o ka mīkini no ka wela nui
- ʻIke hewa mamao a me nā hana hoʻāla
V. Ke Kaʻina Koho i Manaʻo ʻia
Ma muli o ka loiloi i luna, pono e hahai ke koho ʻana o nā crane no nā kahua aila ma waho i ke kaʻina hana penei:
KaʻAnuʻu Hana 1: E wehewehe i nā koi hana. E ʻike i nā ʻano, ka alapine (frequency), ka hiki ke hāpai nui loa, ka radius hana nui loa, a me ke kiʻekiʻe hāpai e pono ai no nā hana hāpai o kēlā me kēia lā o ke kahua.
KaʻAnuʻu Hana 2: E loiloi i nā kūlana o ke kaiapuni. E kālailai i nā kūlana o ka makani a me ka nalu, ka helu o ka palaho o ka paʻakai, ka hoʻokaʻawale ʻana o ka ʻāpana pale pahū, a me nā mea ʻē aʻe o ke kaiapuni ma ka ʻāpana kai kahi i loaʻa ai ke kahua.
KaʻAnuʻu Hana 3: E hoʻoholo i nā kūlana hoʻokō. E wehewehe i nā kikoʻī e hahai ʻia (e like me API Spec 2C, SY/T 10003, a pēlā aku) a me nā palapala hōʻoia o ka hui hoʻokaʻawale i koi ʻia (e like me ABS, CCS, BV, DNV, a pēlā aku).
KaʻAnuʻu Hana 4: Koho i ke ʻano kūkulu. E koho ma waena o ka telescopic boom, lattice boom, a me ka knuckle boom e pili ana i ka hakahaka o ka papahele paepae, nā koi maʻalahi o ka hana, a me nā pono hiki ke hāpai.
KaʻAnuʻu Hana 5: E nānā i nā hōʻoia o ka mea hoʻolako. E loiloi inā loaʻa i ka mea hoʻolako nā palapala hōʻoia honua kūpono, ka ʻike papahana ma waho, a me nā hiki ke lawelawe ma hope o ke kūʻai aku.
KaʻAnuʻu Hana 6: Loiloi i ke kumukūʻai holoʻokoʻa o ke ola holoʻokoʻa. ʻAʻole wale e noʻonoʻo i ke kumukūʻai kūʻai, akā e loiloi pū i nā mea lōʻihi e like me ke kumukūʻai hoʻonohonoho, ke kumukūʻai mālama, ke kumukūʻai hoʻohana ikehu, a me ka loaʻa ʻana o nā ʻāpana ʻē aʻe.
ʻO ke koho ʻana i nā crane no nā kahua aila ma waho he papahana ʻōnaehana e pili ana i nā ʻano like ʻole e pili ana i ka palekana, ka ʻenehana, ka hoʻokele waiwai, a me ka mālama ʻana. Mai ka pili ʻana i nā kūlana honua e like me API Spec 2C, a hiki i nā kālepa ma waena o nā ʻano kūkulu e like me ka telescopic boom, lattice boom, a me knuckle boom, a i ka hoʻohālikelike pololei ʻana o nā palena koʻikoʻi e like me ka hiki ke hāpai, ka radius hana, ka pale pahū a me nā koi pale corrosion - pili pololei kēlā me kēia kiko hoʻoholo i ka palekana hana o ka paepae a me ka pono hana.
ʻO MAXTECH, ma ke ʻano he mea hana ʻoihana o nā lako moana a me ke awa, hāʻawi i kahi ākea o nā huahana crane offshore e uhi ana i ka telescopic boom, knuckle boom, a me nā ʻano ʻē aʻe, me nā hiki ke hāpai mai 1 ton a 140 tons, ka lōʻihi o ka boom a hiki i 47.5 mika, a me nā palapala hōʻoia o ka hui hoʻokaʻawale honua he nui e like me ABS, BV, CCS, DNV, KR, a me RS. Hiki i ka hui ʻenekinia o MAXTECH ke hāʻawi i nā ʻōlelo aʻoaʻo koho crane i hana kūikawā ʻia a me nā hoʻonā loea e pili ana i nā kūlana hana kikoʻī, nā kumu kaiapuni, a me nā koi hoʻokō o nā kahua offshore, e kōkua ana i nā mea kūʻai aku e ʻike i ke kaulike kūpono ma waena o ka palekana, ka hilinaʻi, a me ka hoʻokele waiwai.
