Preliminary Performance Assessment June 2002

ALASKA REGION RESEARCH VESSEL (ARRV) Preliminary Performance Assessment June 2002

Alaska Region Research Vessel Model Tests Ice Performance • Masa Arctic Research Centre (MARC), Helsinki • Attendees: – Robert Elsner, University of Alaska – Arno Keinonen, AKAC Inc. – Justin Morgan, The Glosten Associates Resistance, Propulsion, and Seakeeping • VTT, Helsinki • Attendees: – Bruce Hutchison, The Glosten Associates

Alaska Region Research Vessel Model Test Objectives

Performance Verification • Ice Capability • Full-scale Trials Prediction • Seakeeping Assessment • Maneuvering

Alaska Region Research Vessel Status

• Ice – completed in April • Resistance - completed mid-May • Seakeeping - completed mid-May • Maneuvering – completed last week • Preliminary results in hand • Expect final report end of month

Alaska Region Research Vessel Model Test Program

Ice Tests • Level ice resistance • Turning in level ice • Breaking out of channel • Channel clearing • Ridge tests

Alaska Region Research Vessel Ice Results

• Quantitative results, conservative – 2.5 ft level ice R Achieved 2.56 ft – 7 ft ridges (sail height) R Achieved 7 ft • Qualitative results – Maintains maneuverability close to limiting ice thickness. – Clear wake for scientific deployment – Independent operability in Bering Sea – Extended season north of Bering Strait
