Diesel Electric Research Vessel for U of Delaware

Dakota Creek Industries of Anacortes Washington has earned a reputation for versatility in building every thing from large steel fishing vessels for the Bering Sea, 10,000 HP response tugs for Valdez and aluminum catamaran fast ferries. Their latest project is a 146 x 33 diesel electric vessel for the University of Delaware. Designed my Bay Marine of Rhode Island, the new marine research vessel will have a steel hull and an aluminum superstructure.

With accommodation for 12 scientists in addition to her crew of ten, additional accommodation can be added through the use of a removable van and making up the conference room as a bunk room. In this configuration the boat will accommodate up to 20 researchers. She will operate primarily in the Mid-Atlantic region, including the Delaware and Chesapeake bays, with occasional research missions as far north as the Gulf of Maine, as far south as Florida, and as far east as Bermuda. her maximum time at sea on a single expedition, will be 21 days. The vessel is expected to spend an average of 200 days at sea per year.

The vessel is designed as a low noise research vessel with four Cummins KTA19 M3 460 kW Gensets. These power a DC/AC electrical propulsion package from ASIRobicon ( www.asirobicon.com ) The propulsion is through a pair of Schottel SRP 330 Z drives with a single Schottel STT 110 LK Bowthruster. To assure quite operation the Schottle Z-drives are flex mounted and the propellers are configured for pulling. Two additional Cummings KTA 19 gensets are mounted on a "floating raft" for use in "quite mode" operation. There will be extensive use of acoustic treatment including tiles and vibration isolation through out the vessel.

With a design speed of 12 knots the vessel has tankage for 16,180 gallons of fuel and 2800 gallons of fresh water. Following her sea trials in the fall of 2005, the new vessel will be transported by heavy lift ship through the Panama Canal to the east coast from her builder in Puget Sound. Once there, she will replace the University of Delaware’s 120-foot research vessel Cape Henlopen, which has been in service to the oceanographic community since 1976
