Quiet Power for New American Research
01 Jun 2004
Dakota Creek Industries ofAnacortes, Washington USA has earned a reputation for versatility. Their latest project is a 146m x 33m diesel electric vessel for the University of Delawar e. Designed by BayMarine of Rhode Island, the new marine research vessel will have a steel hull and an aluminum superstructure.
There is accommodation for 12 scientists in addition to its crew of 10. The vessel is expected to spend an average of 200 days at sea per year, with the maximum for a single expedition being 21 days.
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. The propulsion is through a pair of Schottel SRP 330 Z drives with a single Schottel STT 110 LK Bowthruster. To assure quiet 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.
