New Ferry Drops Fuel Use 30%

The operator of a ferry service in the U.S. state of Rhode Island says a new catamaran using a fuel-efficient MTU Series 4000 engine is using 30 percent less fuel than a larger vessel previously used on the route, according to Tognum America (Tognum), which produces the MTU systems.

The 34-meter, 150-passenger vessel, Ava Pearl, makes three daily round trips of 104 miles and logged more than 18,700 sea-miles in its first two months of operations.

The MTU engines, produced by Tognum and supplied by New England Detroit Diesel Allison (NEDDA), offer 1,851 horsepower, and they are continuous-rated to extend the time between overhauls to at least 30,000 hours.

"The vessel is performing up to our expectations," said Charles A. Donadio Jr., president and owner of Rhode Island Fast Ferry.

"The ride is very smooth and we're enjoying a 30 percent fuel savings compared to a larger vessel we used to use on this route. The new Ava Pearl was designed and built just specifically for the open waters between Rhode Island and the island of Martha's Vineyard."

The vessel was designed by Incat Crowther and built by Gladding-Hearn Shipbuilding, and is propeller-driven, something Donadio said makes it more efficient at its 29.5 knot operating speed than water jets used in the previous vessel.

Tognum says the MTU Series 4000 engines offer up to 5 percent improved fuel economy, lower life-cycle costs, and increased durability and availability compared with EPA Tier 2 engines.
