  1. ALASKA REGION RESEARCH VESSEL Concept Design Report Summary Alaska Region Research Vessel

  2. DESIGN OBJECTIVES • Meet Scientific Mission Requirements - Published 1999 • Larger More Capable Replacement for R/V Alpha Helix • Year-round Operation in High Latitudes • Year-round Operations in any Location in the Bering Sea Alaska Region Research Vessel

  3. PROCESSJoint Oversight Committee: University of Alaska Fairbanks and Woods Hole Oceanographic Institution • University of Alaska Fairbanks Vera Alexander, Chair Robert Elsner Thomas Smith Terry Whitledge Thomas Weingartner • Woods Hole Oceanographic Institution Richard Pittenger Robertson Dinsmore Joe Coburn Alaska Region Research Vessel

  4. PROCESSAdvisory Committee Provided Project Review • Mike Reeve, National Science Foundation • E.R. Dolly Dieter, National Science Foundation • Knut Aagaard, Polar Science Center, Univ. of Washington • Larry Atkinson, Center for Coastal Physical Oceanography, Old Dominion University • John Christensen, Bigelow Laboratory • George Hunt, Dept. of Ecology and Evolutionary Biology, University of California Irvine • Suzanne Strom, Western Washington University • James Meehan, National Marine Fisheries Service, NOAA • Mike Prince, UNOLS Alaska Region Research Vessel

  5. CURRENT STATUS • Concept Design – Completed August 1 • Preliminary Design and Model Testing – 3rd quarter 2001 to 1st quarter 2002 • Contract Design – Complete by end of 2002 Alaska Region Research Vessel

  6. MAJOR DESIGN CHALLENGES International Council for the Exploration of the Sea (ICES) Cooperative Report #209 goal in SMR • ICES acoustic levels incompatible with hull form and propulsion system needed for operating in and around ice. • “Quiet” propeller will be included and radiated noise to be as low as practicable. Alaska Region Research Vessel

  7. MAJOR DESIGN CHALLENGES (cont’d) Low open water resistance versus ice capability • “Reamers” and ice wedge add to resistance but improve ability to work in and around ice. • Trade-offs show added cost for ice capable features – design does include them. • Power to be increased 10 to 15% to improve open water speed capability. Alaska Region Research Vessel

  8. MAJOR DESIGN CHALLENGES (cont’d) Seakeeping versus Ice Capability • Trade-offs indicate ice capability features enhance seakeeping ability. • Simple bilge keels not practical in ice operations. • “Centerboard” will be used for transducer mounts and to act as roll damper. Alaska Region Research Vessel

  9. MAJOR DESIGN CHALLENGES (cont’d) Range and Endurance versus Vessel Size and Cost • Endurance drives vessel size. • Ship length overall 226 feet – needed to meet SMR mission profile. • SMR originally requested ship <200 feet. Alaska Region Research Vessel

  10. CHARACTERISTICS • Length, overall………………………………... 226'-0" • Length, design waterline……………………. 200'-0" • Beam, maximum w/o reamer…………………. 48'-0" • Beam, maximum w/ reamer………………….. 52'-0" • Draft, at design waterline…………………….. 18'-0" • Depth, at amidships to main deck…………… 29'-0" • Displacement, at design waterline….. 2,800 LTSW • Total speed…………………………………. 14 knots • Cruising speed………………………………. 12 knots Alaska Region Research Vessel

  11. CAPACITIES • Fuel capacity………………………... 148,000 gallons • Ballast capacity…………………..…. 200,000 gallons • Fresh water capacity………………….. 4,300 gallons • Range…………………….….. 18,000 n.m. @ 12 knots • Endurance – overall………………………….. 45 days • Provisions & human support consumable endurance……………………………………… 60 days • Variable scientific equipment capacity……. 100 LT • Level ice performance……….…. 2.17 feet @ 2 knots • Installed power………………………………. 5000 HP Alaska Region Research Vessel

  12. CAPABILITIESSeakeeping Criteria Vertical Acceleration (ref. SMR)……………………… 0.20g Roll (ref. Hosada 1985, Nordforsk)…………………… 3.0° Pitch (ref. Hosada 1985, Comstock)…………………… 1.5° Horizontal Acceleration (ref. SMR)…………………… 0.10g Alaska Region Research Vessel

  13. SEAKEEPING (cont’d) Achieved • Condition 9 knots Hs 13.12 feet – worst period • Effects measured at main deck, centerline, amidships (except vertical acceleration at transom) Alaska Region Research Vessel

  14. SEAKEEPING(cont’d) Alaska Region Research Vessel

  15. CAPABILITIES • Ice Capability……………….…. ABS A1 Ice Class • Level icebreaking performance…... 2.17' @ 2 knots • Ridge Transit Performance……………….. ~ 7 feet • Installed Power….. 5000 BHP (possibly 10% more) Alaska Region Research Vessel
