Abstract : Diver installed seafloor fasteners are used extensively to stabilize oceanographic cables and to secure structures to rocky areas of the ocean bottom. As part of a program aimed at improving the quality of these seafloor fasteners, an experimental diver-operated grout-dispensing system was developed to be used in conjunction with various groutable fasteners. The experimental grout dispenser consists of a low-speed, high-torque hydraulic motor coupled to a progressing cavity grout pump and underwater exchangeable hoppers which allow continuous pumping of premixed grout at 3 gpm and 80 psi over ambient pressure.
