A mechanical snubber is a mechanical device designed to protect components from excess shock or sway caused by seismic disturbances or other transient forces. [1] During normal operating conditions, the snubber allows for movement in tension and compression. [2] When an impulse event occurs, the snubber becomes activated and acts as a restraint ...
The properties of chain, versus wire, mooring lines have been investigated, with chain mooring lines causing reductions in anchor capacity of up to 70%. [6] Thus, where appropriate and cost-efficient, wire mooring lines should be used. The embedded section of a mooring line contributes to the anchor's holding capacity against horizontal movement.
Snubbers allow for free thermal movement of a component during regular conditions, but restrain the component in irregular conditions. [6] A hydraulic snubber allows for pipe deflection under normal operating conditions. When subjected to an impulse load, the snubber becomes activated and acts as a restraint in order to restrict pipe movement. [7]
Adjustable fairlead (lower right) leading to winch on sailboat Fairlead (Chock style) Three mooring lines running through fairlead on a Royal New Zealand Navy ship.. A fairlead is a turning point for running rigging like rope, chain, wire or line, that guides that line such that the "lead" is "fair", and therefore low friction and low chafe. [1]
225k Snubbing Unit 340k units are designed to perform live and dead well interventions on both land & offshore.. Snubbing is a type of heavy well intervention performed on oil and gas wells.
The snubber is therefore required to extend or retract with the normal operation of the pipe work. The snubber has low resistance to movement at very low velocities. Mechanical snubber: Whilst having the same application as the hydraulic snubber, retardation of the pipe is due to centrifugal braking within the snubber. A split flywheel is made ...
