  • Method of placing a web
    Patent number: 4475846
    Abstract: A method and apparatus for laying a web in a submerged condition on an entrenchment floor includes wrapping a web onto a drum as said drum is floating on a water surface of the entrenchment, navigating the wrapped drum to a beginning section of the entrenchment, and unwinding the drum as it is floating on the entrenchment while further navigating the drum. Water is pumped from a section of the entrenchment already layed with the web, thus imparting an unwinding force to the drum and giving the web a convex shape along the portion of the web which extends from the drum to the entrenchment floor.
