Projects

Hampton Roads Harbor’s Magann W.F. Corp recently repowered the steel tug Miss Anne with the help of Western Branch Diesel, Colonna’s Shipyard and Volvo Penta. Her original Detroit Diesel Series 60 engines were removed and replaced by a pair of 650hp D16-MH Volvo engines mated to Twin Disc 5170MGX gears.

Magann personnel removed the old Series 60 engines, gears, and controls and prepared the vessel for the installation of the Volvo engines and Twin Disc gears. Magann project manager Jeff Torrey and crew assisted by Team WBD installed the new Volvo engines ahead of the vessel going into Colonna’s Shipyard for keel cooler installation and shaft work. Upon leaving Colonna’s Shipyard, Miss Anne returned to WBD’s Portsmouth, VA branch dock.

Magann personnel assisted by WBD’s Larry Ross, along with Volvo’s Drew Pelton completed the installation of the new engines and gears including engine alignment, exhaust, fuel, electrical and Volvo EVC 2 control systems. Once all work was complete, Miss Anne endured two full days of successful bollard push tests and river trials with Volvo representatives and WBD personnel on board. The repowered tug spent a couple weeks working in the harbor before returning to the WBD Portsmouth dock for some control and gear system updates by Volvo and Twin Disc factory representatives.
