13

Hydrocarbon exploitation in ultra deep water

and arctic areas define new requirements:

• Limited support from surface

vessels

• Demand for all-year inspection and

intervention operations

• Permanently installed multitasking

hybrid underwater vehicles

(ROV/AUV) is enabling technology

• Subsea energy recharging and

high bandwidth communication

hubs are required

• Robust control systems handling

multi-regime operations to be

designed

Ice Management Research cooperation with Kongsberg Maritime

• Ice mapping using sonar • Environmental

monitoring

• Survey operations

• Inspection

Drilling needs new solutions

• Arctic drilling ship

• Drilling under ice

• Drilling from

onshore

Sustainable Arctic Sea Transport – Challenges and Focus Areas

Challenges • Individual vessel design for extreme conditions • Safe operations and transport • Fleet and operations management in remote

locations

Focus Areas • Design of the individual vessel for Arctic conditions • Simulation-based design of ice going vessels • Identification of the optimum fleet size and mix for

Arctic conditions

WP4 - Floating Structures in Ice

Goals:

To develop new knowledge, analytical and numerical models needed

by the industry to improve the prediction of loads exerted by first-

year and multi-year level ice and ridges as well as icebergs on

floating structures.

This also implies prediction of the behaviour and performance of the

structures.
