Highlights Viking Neptun, Eidesvik’s biggest vessel, is developed by Eidesvik in close cooperation with Salt Ship Design and Kleven group. One of its unique qualities is focus on high redundancy which makes it extremely reliable in all operations. A stable platform for subsea operations • Large beam provides possibility to carry high deckload •
Optimum tank arrangement ensure good motion characteristics with low deck load
•
‘Clean deck’ with no mooring equipment, centralized ventilation/ piping and large parts of bulwark removable
•
Efficient crane lift of items with wide range of dimensions/ weights
•
Deck strengthening for high flexibility in equipment positioning
High redundancy and robust solutions • Proven technology and renowned makers •
CP propellers for reduced down- time Large number of thrusters, and flexible power distribution
•
Large bilge keels, optimized roll reduction tanks and efficient reduction of moonpool pumping
•
•
Comprehensive documentation from model tests in MARINTEK’s ocean basin
Low emissions & fuel consumption • Hull & propeller optimized for typical operational mode
Flexible deck-layout for wide range of deckspread • Feasibility studies performed for numerous deck spreads
•
Extensive analysis and model testing resulted in outstanding hydrodynamic performance
