  • Barge spud greasing system
    Patent number: 11585487
    Abstract: A spud greasing system includes a spudwell and a spud configured to slidingly engage with the spudwell between a deployed position and an undeployed position. The spud includes an access window configured to align and correspond with a window of the spudwell when the spud is in the undeployed position. A sheave assembly is mounted in the spud and includes a first sheave and a second sheave rotationally mounted proximate a front end and a back end of the housing, respectively. When the spud is in the undeployed position, a grease supply is configured to be selectively connected to a supply pipe through the window and access window of the spudwell and spud thereby supplying grease to the first sheave of the sheave assembly without removing the spud from the spudwell.
