PROJECT SERVICES Twenty-two miles off the coast of Southern California you’ll find Catalina Island, the southernmost island within California’s Channel Islands. Catalina Island has been a stop for smugglers, gold miners, pirates, hunters, the Union army and missionaries, and was a popular spot for the Hollywood elite during the 1930s, ’40s and ’50s. Today, it’s a resort community that is home to 60 plant, animal and insect species that aren’t found anywhere else in the world. PVA Vessel member Catalina Express, San Pedro, CA, offers year- round ferry transportation to the island, whisking more than a million travelers a year to the island from its ports in San Catalina Express Upgrades Engines to Meet Emissions Standards Pedro, Long Beach and Dana Point. Its fleet of eight fast, environmentally- sensitive ferries are powered by quiet, fuel-efficient PVA Associate member MTU engines that reduce nitrogen oxide emissions and diesel particu- lates. The ferries are also intermittently repowered to meet emissions regula- tions set by the CaliforniaAir Resources Board (CARB), which are often more demanding than in the rest of the U.S. Repowering a Starship The MTU-powered Starship Express, a 300-passenger catamaran, was recently repowered with Tier 3 engine technology to keep pace with CARB’s regulations. It is one of eight Catalina Express ferries that make the hour-long run between Catalina Island and Long Beach, cruising at speeds up to 35 knots. “Starship Express is the latest vessel in our fleet to be repowered with lower emission engines,” said Catalina Express President Greg Bombard. No grant funding was used for this project. Catalina Express has kept its fleet up-to-date by working with its MTU distributor, PVA Associate member Valley Power Systems. With the engine repower, the Starship’s diesel engine power leapt from EPATier 1 to EPATier 3, meeting CARB’s repower regula- tions. After six months, the repowered Starship recently reentered service and has improved environmental impact. The original 16V 4000 M70 engines (rated at 3,110 horsepower at 2,000 rpm) were replaced with 16V 4000 M64 engines (rated at 2,680 horsepower at 1,800 rpm). “The original engines only used 2,600 horsepower in its daily operation. With the new engines, the M64, Catalina Express achieves the horse- power they need with improved time between overhauls and overall lifecycle costs,” said Jeff Sisco, technical support specialist, Valley Power Systems. “To prepare for this repower, we had to run testing with different passenger counts to make sure the Starship could meet its required speed with the new
