| Australian Register of Shipping Official Number | 860820 | |
| IMO Number | 9616888 | |
| Endurance | 60 days | |
| Cruising speed | 11 knots | |
| Range | Approximately 10,000 nautical miles | |
| Accommodation | Total 60 berths: 20 ship crew and 40 science party with latter comprised of approximately 10 MNF technical support staff and 30 researchers (depending on research plan and support requirements) | |
| Diesel Generators | 3 x 9 cylinder 3000kW MaK Diesel engines each coupled to a 690V AC Generator | |
