Phase 1 Feasibility Study: Seawater Hydraulic Transfer Pump
1998
Kunsemiller, John
The Naval Facilities Engineering Service Center (NFESC) has completed a Phase 1 feasibility study to determine whether or not a seawater hydraulic design for the CCN-150 transfer pump system would reduce weight thereby making the system easier for U.S. Coast Guard (USCG) Strike Teams to deploy. The feasibility study included a review of commercially available seawater hydraulic system hardware applicable to this conversion and development of a seawater hydraulic transfer pump system design concept. Based on results of the literature survey, concept development studies, and USCG National Strike Force operational requirements, it was determined that an open circuit seawater hydraulic system configuration of the transfer pump system with a lightweight hydraulic power source can provide a 3,000 pound savings over the present oil hydraulic system powered by the MOD 6 hydraulic power source. A secondary benefit of this seawater hydraulic system is improved system safety and environmental compliance through the elimination of hazardous hydraulic oil. These findings support NFESC's recommendation to proceed with a Phase 2 demonstration of a seawater hydraulic powered CCN-150 transfer pump. It has also been determined that a reduction in transfer pump system weight and an improvement in pump performance can be achieved without conversion to seawater hydraulic operation.
