Rutter sigma S6 Oil Spill Detection and Monitoring System

Early Detection Protects the Environment and Reduces Recovery Costs

Combining proven strength in early detection with tools that generate essential information about oil spill volume, thickness, deformation, and drift Rutter sigma S6 Oil Spill Detection systems provide accurate and reportable current state data and intelligence. 

  • Scans the water surface over a 50 sq mi area on a 24/7 basis to ensure early detection

  • Share information in real time with spill response teams, management, and other key stakeholders.

  • Permit recovery operations to continue 24/7 by giving immediate information on the status of the spill, day or night.

The Rutter sigma S6 Oil Spill Detection systems protect offshore, onshore, and corporate assets around the world. 

Oil Spill display

As one of the first companies to develop a radar-based oil detection system, Rutter systems have been extensively tested and proven effective in independent trials conducted by the Norwegian Clean Seas Association for Operating Companies (NOFO).

Since introducing OSD systems in 2009, Rutter has established an extensive reference list. sigma S6 systems are installed in fixed platforms, FPSO's, offshore workboats, patrol vessels, and specialty clean-up vessels in Brazil, the North Sea, Gulf of Mexico, Eastern Canada, China, and Russia.  For northern drilling operations, Rutter OSD systems have been integrated with the sigma S6 Ice Navigator™ to provide simultaneous oil and ice detection and tracking on one display.

Low False Alarm Rates

sigma S6 Oil Spill Detection systems permit the user to set parameters which mitigate the occurrence of false alarm spill detections. Users can select regions of the scan area not to consider based on known anomalies and can also prescribe specific ranges or distances from the scanner to exclude for detection. Minimum alarm thresholds can also be set.

Automatic Spill Detection and Outlining

When the system alarms the operator can either acknowledge the alarm or cancel it based upon ability to validate the anomaly as oil. When the alarm is acknowledged the anomaly is treated as a spill.  It is automatically outlined and a vector displayed.  Historical spill outlines are maintained and displayed, revealing drift and dispersion information.

Inferred Thickness and Estimated Volume

As thicker areas of a spill dampen the radar signal more than thinner areas, thickness can be inferred to more efficient cleanup. Modeled after the AMSA Oil Spill Monitoring Handbook method, user-entered thickness values are paired with auto-calculated area information to provide and inferred oil volume.  This information enable operators to determine if a growing spill area is related to increasing oil volume or dispersion.

Camera Integration and Control

Integration and control of EO/IR cameras is facilitated through the sigma S6 user interface.  Features include the ability to support multiple cameras, intelligent selection of the best camera view for specific spills or targets, and automatic slewing to a spill alarm area for prompt verification. Cameras will automatically track a spill as it moves and disperses.

Information Sharing and Portability

OSD-500 can export ESRI outlines to VTMS and tactical spill response systems as visual overlays.  Screen captures can be exported to system folders for remote display and full sigma S6 data can be shared by networked Remote Clients or with bespoke information systems via the sigma S6 programming interface.
