Hello everyone,
I am a student at the Marine Institute of Memorial University of Newfoundland. Myself and a few classmates are currently developing an underwater trencher for our technical project due in April of this year. We are looking to use hydraulics; however, due to a limited budget we can not afford to buy an HPU (hydraulic power unit). We have a pump, motor, and reservoir, but none of these are submersible. Does anyone have any ideas or suggestions on how we could make this work without going completely electric? Thanks everyone!
