Marine Diving Solutions was awarded this contract to provide and install one hydraulic power unit (HPU) on the 1,337’ elevation level of the intake tower and incorporate the unit both hydraulically and electrically to the existing HPU system. The HPU was to be designed and fabricated to conform to the specifications of the contract as well as be installed into the existing unit on site and tested. Project installation was scheduled for winter months for minimum environmental impact. Due to aging infrastructure of gate cylinders, MDS was issued a modification to our contract for the rehabilitation of E1 gate cylinder.
