Satellite monitoring of oil spills at sea

Beredskapskonferansen Tromsø, mai 2010Jan Petter Pedersen, Vice President, KSAT

Presentation content

• Principles for satellite radar detection of oil spills

• Introducing the operational service chain

• Operational scenarios• Regular monitoring service• Emergencies

• Concluding perspectives

Satellite radar detection of oil at sea

Recent oil spill(80 km)

Polar orbit

Equatorial orbit

• One image every 1 to 4 days, depending on latitude

• Wind speed detection window app 5-18 m/s

/ 4 / 10 Apr 2023

KSAT - Oil Spill Detection Service

• Operational service since 1998• Radar satellites (primary)• Optical satellites

(supplementary)• Oil spill information delivery

• Available < 30-60 minutes• Phone, e-mail, SMS, Web

• Oil spill report:• Time, Location, ….• Source – AIS when present

• KSAT responsibility ends at spill reporting

• Development since early-90• Involving national users • National activity given inter-

national positions

Coordinated surveillance, satellite and airplane observation

/ 5 / 10 Apr 2023

An integrated system combining available surveillance means represents theoptimal and most cost efficient solution for environmental monitoring

Satellite images may be used for planning of airplane activity

Identification of polluting sourceCombining satellite images with AIS

/ 8 / 10 Apr 2023

Oil spill outside the Norwegian coast, ships in the area. Warning with

excact position, size and confidence level is given.

Combined with AIS, tracked back, one of the ship lanes closely corresponds with the potensial spill.

The vessel can easily be identified, and authorities can decide on further action.

/ 9 / 10 Apr 2023

The regular monitoring scenario

• Aim: Detect illegal discharges, identify and prosecute the polluting source

• Users define their coverage needs• Geographical area• Frequency of repetivity (70 deg N: 3-4 images per 2 days)

• KSAT initial respond to user requirements• Provide satellite data, primary sources – radar missions• Coverage information to user, e.g. for aircraft planning• Assure additional information access (metocean, AIS, ..)

• Service operations• Data acquisition, processing and analysis• Spill detection, source identification• Time requirements: 15, 30, 60 minutes• Information dissemination

• Direct reporting (mail, phone)

• Service web browser• Primary service information interface• Image and information database• Planning, analysis, detection information

• User responsibility• Follow-up of satellite information• Report verification (aircraft, other, …)• Feedback to KSAT

Subject: SV: Ref. telefonsamtale mulig oljesøl - båtens posisjon

På bakgrunn av satelittobservasjonen ble et fartøy i området kontaktet. De kunne ikke verifisere sølet. Et Orion-fly meldte om en oljestripe på nærmere 3 nautiske mil i lengde og 10-15 meter i bredde, ca 8-9 timer etter satellittbildet.

Et skip – mest sannsynlig fartøyet dere koblet sammen med AIS-info, har sluppet ut olje.

Med bakgrunn i at vi hadde få tilgjengelige fartøyressurser i området prioriterte vi ikke denne gang å få tatt prøver av sølet. Men vi jobber med å bedre mulighetene for prøvetaking, og er fortsatt meget interessert i å stoppe denne type ulovlig forurensning.

The emergency scenario

• Aim: Update the recognised situation picture• Geographical area defined by emergency case• User needs

• Maximum satellite coverage• Single service provider interface

• KSAT initial respond to user requirements• Provide satellite data access – all available missions (radar,

optical)• Coverage information to user, e.g. for resource planning• Assure additional information access (metocean, AIS)

• Service operations• Data acquisition, processing and analysis• Spill detection, source identification• Time requirements (Quasi)Real-time• Information dissemination: Direct reporting (mail, phone)

• Service web browser• Primary service information interface• Image database for post-analysis• Planning, analysis, detection information

• User responsibility• Implement satellite information into operations
