It has a landing sub, which connect to the need position of drill string then put into the well, help check valve into place, drop-in check valve is a kind of single flow check valve, stored on the platform, when found blowout omen, drop it into drill pipe bore, just once time drop in can be into place on the land sub automatically, When high pressure flow of downhole, the check valve could cut off high pressure flow of upward jet in the drill string.
