(2) Lokacin da babu kayan aikin hakowa a cikin rijiyar, cikakken ragon hatimi zai iya rufe kan rijiyar;

(3) Lokacin da ya zama dole a yanke kayan aikin hakowa a cikin rijiyar kuma a rufe bakin rijiyar gaba daya, za a iya amfani da ragon da aka yanke don yanke kayan aikin hakowa a cikin rijiyar kuma a rufe bakin rijiyar gaba daya;

(4) Ragon wasu masu hana busa ragon yana ba da damar ɗaukar kaya kuma ana iya amfani da shi don dakatar da kayan aikin hakowa;

(5) Akwai rami na gefe akan harsashi na ragon BOP, wanda zai iya amfani da ramin gefen ramin matsi;

(6) Ana iya amfani da Ram BOP don rufe rijiyar na dogon lokaci;

3.Zaɓin haɗin BOP

Babban abubuwan da za a yi la'akari da su a cikin zaɓin haɗin haɗin hydraulic busa mai hana ruwa sune: nau'in rijiyar, matsin lamba, girman casing, nau'in ruwan halitta, tasirin yanayi, buƙatun kare muhalli, da sauransu.

(1) Zaɓin matakin matsa lamba

An ƙaddara shi da matsakaicin matsa lamba na rijiyar da ake tsammanin haɗin BOP zai iya jurewa. Akwai matakan matsa lamba biyar na BOP: 14MPa, 21MPa, 35MPa, 70MPa, 105MPa, 140MPa.

(2) Zaɓin hanya

Diamita na haɗin BOP ya dogara da girman casing a cikin tsarin tsarin rijiyar, wato, dole ne ya zama dan kadan ya fi girma fiye da diamita na waje na casing wanda aka haɗa shi. Akwai tara nau'i na busa diamita: 180mm, 230mm, 280mm, 346mm, 426mm, 476mm, 528mm, 540mm, 680mm. Daga cikin su, 230mm, 280mm, 346mm da 540mm ana amfani da su a filin.

(3) Zaɓin nau'in haɗin gwiwa

Zaɓin nau'in haɗin gwiwa ya dogara ne akan matsa lamba samu, buƙatun aikin hakowa, tsarin aikin hakowa da yanayin tallafawa kayan aiki.
