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

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

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

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

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
