ʻO ka ʻōnaehana hoʻokele luna luna / haʻahaʻa IBOP hui no Varco/Canrig/TESCO/BPM/JH/HONGHUA
Nā hiʻohiʻona
ʻO nā ʻāpana ʻāpana IBOP no Varco/Canrig/TESCO/BPM/JH/HONGHUA ʻO nā ʻōnaehana hoʻokele kiʻekiʻe ma ka ʻaila ʻaila ʻaila.
ʻO ka mea pale i loko, i ʻike ʻia ʻo BOP i loko, he mea hana kūʻokoʻa i hiki ke kahakaha ʻia ma o ka BOP i mea e hoʻopili ai me nā mea hana wili hou i ka hiki. I ka wā e hāpai ana i nā mea hana wili, hāʻawi ka mea pale i loko o ka blowout i nā pōmaikaʻi he nui, me ke kaomi kiʻekiʻe, hilinaʻi i hoʻopaʻa ʻia, maʻalahi o ka hoʻohana, hoʻololi wikiwiki, a me nā mea hou aku.
ʻO nā ʻano ʻelua o IBOP no ka hoʻokele kiʻekiʻe ʻo Upper IBOP a me Lower IBOP. ʻO kēia nā valve mana i hoʻohana pū ʻia me ka ʻōnaehana hoʻokele kiʻekiʻe. ʻO ka maʻamau, hoʻopili ʻia ka mea hoʻoheheʻe kiʻekiʻe kiʻekiʻe i ʻelua valves. Hoʻohana ka IBOP i kahi sila metala hilinaʻi loa. No laila, hiki iā ia ke pale i ke kaomi ikaika ma luna a ma lalo. Hiki ke kiʻi i kahi kaomi hana o 10,000 a i ʻole 15,000 PSI.
Hoʻomaʻamaʻa kūikawā ʻia nā ʻāpana kūloko āpau, me ka lua o ke kino valve, e pale aku i ka corrosion a hōʻoia i ka lōʻihi o ke ola lawelawe. Pono e pani ʻia ka IBOP haʻahaʻa me ka lima i ka wā e kiki ai ka pūnāwai, akā hiki ke pani ʻia ka IBOP luna ma o ka mana mamao. Hoʻokele ʻia ka IBOP kiʻekiʻe e wehe ʻia e kahi hui i kapa ʻia ʻo ka top drive actuator. Hoʻohana like ia me nā mea hana ʻē aʻe e hoʻoponopono i ka wehe ʻana a me ka pani ʻana o ka Upper IBOP.
