Challenges for ships operating in Arctic ice
Strategic level
• Finding the safest way
– exposed to various risks related to ice (dependent of ship ice class)
• Most efficient way, save fuel
• Optimize time
• Optimize data and communication costs
Operational level (on-board crew)
• Ice situation is continuously changing due to ice drift
– causing ice pressure areas/ridges (danger)
• More or less alone if anything happens
• Environmental; Darkness…
• Retrieving ice information at the right level and right time efficiently
– Transforming data into operational (detailed) route planning
– Finding areas of open waters within the ice (opportunity)

year, taking the

Tor Viking
• Combined AHTS & Ice-breaker (smaller than e.g. IB Oden)
– DNV Icebreaker Ice-10 notation
• Capable of operations in harsh environment offshore regions and Arctic/Sub-
Arctic regions
• Transas ECDIS
• VSAT & Iridium OP– V-Sat Bridge: +46 31 334 4743
– V-Sat Master: +46 31 334 4744
– V-Sat ECR : +46 31 334 4746

– changing weather conditions and ice conditions
has to be considered

The Planned route
- A real challenge
• Seattle Landskrona (Sweden) via NSR
• First time NSR unsupported by Russian ice
breaker
– Icebreaker fleet was either not available
or demanded higher payment to escort
vessels along the route
– Gaining experience operating on their
own, supported by sat.-products
• Save about 12 days compared to sail the
"normal" way via Panama
• 7-8 vessels passing in 2015 (half of 2013
record)
– Probably last ship in 2015 before
completely freezing
• ~10 days within ice, planned 10 knots

Critical key factors
- using SAR-images navigating within ice• Fresh images – ice is drifting
– Dependent of location, more rapid changes within straits
– At least once a day
– On-time image acquisition planning
• Sentinel-1 not continuous coverage
• Schedule might change due to changing ice conditions
• Image resolution – 100 m normally sufficient
• Image transfer method and file sizes
– Data transfer at high latitudes (SatCom), large files is an issue
• ~5 Mbytes could still work
• Costly data communication (Iridium)
– Online viewer solutions do normally not work
• Data formats

Methodology
• Methodology was to download satellite imagery to ECDIS system
– identify leads and cracks with light ice
– then use ice radar to do the local area fine navigation.
• The ship could increase speed from 5 to 12 knots using 3 (of 4) engines
finding those areas with lighter ice

ROUTE PLANNING USING SAR DATA

Changing ice conditions
• Wind
• Ocean currents (tide)
causing ice drift and ice pressure
– In fjord systems and straits the dominant ice drift direction is often based
on tidal currents
– In open sea wind the dominant factor
• Velocity ~3% of wind speed
• ~30 degrees to the right because of coriolis in the Northern Hemisphere
• Ice drift estimated by identifying the same ice floes at two different stages
• Ice compression and cracks are not present at the next stage, or vice versa.
• In Kara Sea experienced north-northwest (tracks in ice by small islands)
• Need to be aware of and/or compensate waypoint planning

Lessons learned
• SAR-imagery is (still) needed for navigation within ice
• Gaps in Sentinel-1 coverage, especially in the eastern part of NSR
– Images for other missions needed (RISAT1, RADARSAT2)
– Continuous update of image acquisition planning is needed when trying to
plan for Sentinel-1 coverage gaps
• Sentinel-1 EW resolution even better than needed for navigation within the ice
• Acquisition planning for a “moving target” is challenging
• ViewIce/PolarIce-tool is mostly intuitive to use
• Ingesting imagery into ECDIS is a challenge
– Testing needed, again and again…
• What SAR-images could be used for onboard use;
– Requires experience in interpretation
– Polynyas
• Images need at least daily, more often if ice drift is significant for the area

Benefits of using NRT SAR imagery for
within ice navigation
• Viking emphasized benefits
– “We found the lead in the satellite image, the speed went up from 5 to 12
knots”
• Saving time
• Saving bunkers
– Risk reduction
• Avoiding danger areas of heavy ice
• Better onboard environment
• Reducing risk of getting stuck in the ice
