The Prince William Sound Aquaculture Corporation (PWSAC) is a non-profit founded in 1974 by a local fishermen’s organization to optimize wild salmon resources in the Prince William Sound and Copper River regions. PWSAC operates five hatcheries to produce ocean-raised wild salmon for commercial, sport, and subsistence fisheries.
MER has been fortunate enough to have PWSAC as a long-standing customer. They contacted us to help replace two 80kW CAT generators at their Main Bay Hatchery.
Initially, the specification called for two stand-alone BOLLARD™ IG100 (100kw) radiator cooled generators. These would augment the 300 kW water turbine on site. It was later decided to add paralleling. Load sharing allows the units to auto start and auto sync as more load is applied. When the load drops, one gen-set can shut down. The other carries the lighter load, saving wear and tear and oil and fuel. The auto start/auto sync is controlled by a Deep Sea 8610. The motor-operated circuit breakers were installed in custom MER panels, with programming and wiring provided by MER. After testing at our new facility in Seattle, the units were shipped to Main Bay and installed on site by our team.
Engine longevity is further extended with SCOR bypass oil filtration. SCOR extends engine life and oil drain intervals by removing contaminants to below .9 microns, neutralizing sulfuric acid, and replenishing additive levels.
For PWSAC, the end result has been a user-friendly generator upgrade with improved efficiency, longevity, utility and savings.
