To insure development of the most reliable total system possible, it is planned to use power in the minimum number of forms practicable. Because of the torque-limiting characteristics of hydraulic motors, actuators, and controls, it appears that a maximum use of hydraulic components will be advisable.

. Concepts for drilling and excavating in and below the ocean bottom. Underwater drilling; Ocean bottom. Figure 27. Potential problem in working a tethered seafloor machine. To insure development of the most reliable total system possible, it is planned to use power in the minimum number of forms practicable. Because of the torque-limiting characteristics of hydraulic motors, actuators, and controls, it appears that a maximum use of hydraulic components will be advisable. If power is supplied to the work site and to the working plat- form through an electrical cable, a central hydraulic pump driven by a totally sealed electric motor will be needed. Whether the hydraulic system will be filled with a petroleum base hydraulic fluid or uses filtered seawater is prob- ably of small consequence, except that precaution must be taken with the 27.
