Fuel Efficiency and Low Noise with Marine Commercial Tugboat Repower

The Miss Anne tugboat has a lengthy history that dates back to the 1950s. The tugboat was repowered using twin Volvo Penta D16C-MHs to revitalize its performance. The project began in June 2015 after Bill Magann, who was the president of W.F. Magann Corp., contacted Western Branch Diesel in Portsmouth, Virginia. Western Branch is a Volvo Penta Power Center dealer. Magann was seeking a high performance marine commercial engine to re-energize Miss Anne.

Increased performance
Increased fuel efficiency and low noise levels are primary features for tugboat owners and operators, which were important factors when considering the repower.

“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. It runs a minimum of 50 to 100 hours per week. This marine diesel engine is 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.

Excellent service by Volvo Penta
“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.”

Advantages of the D16
This marine commercial engine ensures lower diesel fuel consumption, emission levels and noise levels when running. It injects fuel for high pressure and performance, all with easily accessible service points. 

Additionally, all Volvo Penta marine engines are designed with a unique torque. This allows top speeds with lower fuel consumption, load-carrying capability and the ability to maintain a high cruise speed. All of these benefits are possible regardless of the condition at sea. Torque also has a positive impact on the longevity of the engine.
