ABB Shaft Generators, Turbochargers for DFDS Vessels

ABB shaft generators will raise the energy efficiency on two DFDS vessels which have been designed to meet the latest environmental regulations. Two shaft generators will be installed in each of the cargo Ro-Ro ships allowing the main engines to operate at a wider, more optimal speed range. The shaft generator system takes its power from main engines, thereby increasing safety if there is a failure on the auxiliary engine. The ships’ main engines will also be turbocharged by ABB’s latest generation technology.

Oscar B: Power in the River Currants

Since 1925 there has been some form of car ferry crossing of the lower Columbia River from Puget Island on the Washington side to Westport Slough on the Oregon side. In 1959 Wahkiakum County took over operation of the ferry and in 1962 had a steel-hulled ferry, named for the county, built by Nichols Boat Works at Hood River Oregon. This 12-car ferry served until 2015 when the county took delivery of a larger 23-car ferry. This ferry, named Oscar B, after Oscar Bergseng who served as ferry captain for 17 years. He died in 1985 after serving further years as ferry commissioner.
