Miss Anne, a tug built in the 1950s, has been repowered with twin Volvo Penta D16C-MH
engines. The repower project began in June 2015 when Bill Magann, president, W.F. Magann Corp., approached Western Branch Diesel in Portsmouth, Virginia, about re-energizing Miss Anne.
The new engines have brought revived energy and increased performance to the tug.
“The existing DDC Series 60 engines were aged and Magann wanted to repower the boat to increase power and allow the tug to become involved in more projects,” says Tim Walters, marine sales manager, Western Branch Diesel. “We repowered with the 650-horsepower, 1800-RPM, keel-cooled Volvo Penta D16C-MH. The keel-cooled engine was chosen for its fuel efficiency, weight-to-power ratio, and a complementary size to the available space in the engine room.”

Miss Anne moves construction equipment as well as barges along the coast, bays, and rivers, and runs a minimum of 50 to 100 hours per week.
“We performed all service and installation on the boat and engine. The main challenge we had was getting enough propeller under the boat. Volvo Penta has provided great customer service to assist us,” says Walters. “Several companies were watching to see how the project went, it could open up a lot of Volvo Penta business for us.”
The engines are approaching 1,000 hours, and so far, there have been no service calls. “I am told they are much more fuel efficient than the engines we removed. The crew especially likes the low noise level,” says Walters.
