Offshore Structures

Online surveillance - Visualising the problem

Hundreds of offshore structures are operating within sensitive marine areas and it is doubtful whether oil spills are correctly reported. This has been evident on several occasions, where airplanes equipped with airborne surveillance equipment have observed an offshore structure at the time of a significant discharge of oil. The differences between the amount measured by the airplane and the amount reported from the offshore structure often results in cleanup actions being based on incorrect or non-objective information, which is reflected in the inefficient actions taken.

This problem is addressed by the OSIS sensor system providing 24hours a-day surveillance against oil spills. The sensor system will identify and track oil spills from offshore structures and calculate the spill volume with accuracy of 90 percent.

The appllication is illustrated above. The sensor system is available as a manual or automated system.

• The manual system provide the onsite user with a tool to monitor, track and quantify an emission of oil. This is especially useful for self monitoring and control during tanker loadings and other operations where oil spills are a potential risk.
  
• The automated system enables onshore users to be continuously updated with sensor measurements from any offshore location. In case of an oil spill, the estimated contamination area and spill volume is automatically reported to the onshore user. Target groups have access to info screens via a traditional web interface to the OSIS Central Server.
