| Specifications |
| Length overall | Approximately 140 to 165 feet
|
| Draft | 12 feet maximum navigational (with any retractable appendages 15 retracted)
|
| Propulsion | integrated diesel electric propulsion plant and be capable of
20 continuous speed control to ½ rev/minute throughout the entire operating speed range
|
| Speed | maximum speed of at least 12 knots and a sustained speed of 10 to 11 knots in calm seas at full load.
Some science operating profiles will require continuous underway survey or towing operations at speeds from 0 knots up to the normal cruising speed. The design shall consider the impacts on engine operation, maintenance and emissions, exhaust gas ingestion, water making capability, and other factors when on-station or moving at slow speeds for extended periods of 30 time.
|
| Range | 5,400 to 6,500 nautical mile range at sustained speed in calm water.
|
| Endurance | at least 21 days with a surge capacity for an occasional 30 day
25 endurance desirable.
|
| Availability | operate and meet scientific requirements continuously (24
hours per day, 7 days per week) during a 30 day at-sea deployment without sustaining a system failure that cannot be corrected at sea, or that degrades scientific capabilities.
|
| Towing | The ship shall be capable of towing scientific packages with up to 10,000 pounds of towing load at 6 knots and 20,000 pounds of towing load at 4 knots. The ship shall be capable of performing towing operations continuously during an entire cruise (up to 30 days).
|
| Berthing Accommodations |
Permanent berthing accommodations and toilet/showers shall be provided as follows:
14 single staterooms with toilet/shower facilities shared between pairs of single staterooms.
8 to 10 double staterooms with toilet/shower facilities shared between pairs of double staterooms.
|
| Laboratories | A suite of modern, well-equipped laboratories 5 including Main Lab, Wet/Hydro Lab, Computer Lab, and Staging Bay shall be provided. The Main Lab, Wet/Hydro Lab and Staging Bay shall be located adjacent to each other and the Working Deck. It is desirable that the Computer Lab also be located adjacent to the other labs.
