able on many of the legacy ships as they were single-focus ships brought to NOAA when the agency was formed. Even the recently acquired Navy T-AGOS ships were converted as single purpose ships after they were transferred to NOAA. The NSV is expected to provide multi-mission capability. Some flexibility in mission space and equipShip Dimension Use technology to leverage contributions of higher paid scientists Legacy Ships Scientists must ride ship and perform data collection; limited real-time communications capability; generating power limits ability to expand capability
ment on the ship is required to provide this multi mission capability. Following the lead of other ship operators, a "plug and play" capability, where a container can be swapped out to change space configuration in a limited way, will allow added mission flexibility.
New Fishery Survey Vessels Some real-time communications capability; scientists still must ride ship to perform data collection. Power generation can be upgraded to accommodate additional capability. Proposed NOAA Survey Vessel Leverage contribution and knowledge of scientists by using technology to provide real-time connectivity and communication to multiple scientists ashore at different locations with data collection operation. Data collection performed by lower cost science technicians. To be designed acoustically quiet. Larger ship will accommodate greater holding tank capacity for effluents; will require alternative power generation or strong exhaust pollution controls to meet standards.
Limit ship's environmental Impact
Designed to discharge effluents overboard with little to no space to add holding tank capacity; exhaust from old diesel machinery does not meet standards being considered for near future; ships generate a substantial amount of radiated noise affecting quality of data.
First acoustically quiet ship design in NOAA fleet. Added holding capacity for effluents; may need to adapt machinery exhaust to limit exhaust pollution to newer standards.
Capability to support remote Diving operations
Most cannot support operations.
Cannot support operations. Limited space and equipment for diving operations.
Will have hyperbaric chambers and dive facility space to manage equipment, and recharge tanks with special gas mixtures
Mapping capability
Installed mapping capability if ship is dedicated to bathymetry; no other capability. A few ships have an ice belt installed providing limited protection.
Installed capability for biomass and habitat mapping.
Installed capability to address bathymetry, biomass, and habitat mapping needs.
Hull strengthening to address operations in Arctic Region
Ice strengthening added to hull design, but should not operate by itself in Arctic Region
Ice strengthening installed to meet anticipated mission profile for ship. Specific requirements to be determined.

To determine the best alternative to address the requirements of the ten requirements groups, an analysis of alternatives (AoA) was conducted. The AoA was done in two parts: (1) a cost-effectiveness economic analysis based on guidance provided in the Office of Management and Budget (OMB) Circulars A-11 and A-94 and, (2) a program performance analysis that assessed how changes in ship capacity and capability would impact NOAA GPRA measure results. The results of the economic analysis indicate that conwww.seadiscovery.com
structing nine new ships and that conducting one service life extension for a ship that will be 21 years old in FY 2010 is the most cost effective solution.
