  2. Drilling riser - Wikipedia

    en.wikipedia.org/wiki/Drilling_Riser

    Drilling riser joints with buoyancy modules. A drilling riser is a conduit that provides a temporary extension of a subsea oil well to a surface drilling facility. Drilling risers are categorised into two types: marine drilling risers used with subsea blowout preventer (BOP) and generally used by floating drilling vessels; and tie-back drilling risers used with a surface BOP and generally ...

  3. Riser (casting) - Wikipedia

    en.wikipedia.org/wiki/Riser_(casting)

    A riser is categorized based on three criteria: where it is located, whether it is open to the atmosphere, and how it is filled. If the riser is located on the casting then it is known as a top riser, but if it is located next to the casting it is known as a side riser. Top risers are advantageous because they take up less space in the flask ...

    Releasing the cord loop by removing the cable with a tug causes the three-ring system to cascade free and quickly disconnect the riser from the harness. Each ring in the series multiplies the mechanical advantage [ 3 ] of the loop of cord that is held in place by the semi-rigid cable (a Lolon-F or Teflon impregnated plastic coated steel cable ...

  8. Hydraulic tappet - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_tappet

    Hydraulic lifters were nearly universal on cars designed in the 1980s, but some newer cars have reverted to bucket-and-shim mechanical lifters. Although these do not run as quietly and are not maintenance-free, they are cheaper. [citation needed] Nearly all modern non-hydraulic lifter arrangements are on overhead cam engines.
