Automated System

Integrating individual sensors into a comprehensive information system

The automated system is a near real time system where all manual sensors containing module 1 are integrated in a surveillance system covering a defined geographic area from where oil spill data is assessed automatically and the result transmitted directly to the onshore user.

Data is transmitted from the sensors to a Master Unit. In the Master Unit, the OSIS decision software transfers the sensor data into oil spill information which is then transmitted onshore via satellite to a Central Server. In the Central Server, target groups will have access to oil spill information screens via a traditional web interface. The system architecture is illustrated to the right.

The scalability of the system is unlimited as the system can survey an unlimited number of offshore structures simultaneously enabling an unlimited number of worldwide users to access the database after registration in the OSIS Central Server.

The automated system applications are targeted users requiring all oil spill information accessed centrally from a location away from the monitored area. If an oil spill is observed, the automated system triggers an alarm and provides the operator with direct access to the oil spill information for the selected geographic area and the individual sensors mounted within the area.

The OSIS system gives the user direct access to relevant oil spill information through the following information screens.

Login View

When username and password is correctly entered, access is provided to the OSIS Central Server.

A progress bar is shown until the main program is started and connection to the server established.

Surveillance View

Once entered the Central Server, Surveillance View illustrates a user defined geographical area with all the installed sensors presented on the map.

Sensor status is continuously updated and the status reflected in the color. A green dot in the map area indicates that no oil spill is found on the sensor location while a red dot indicates that the sensor has detected an oil spill. Yellow dots indicates that a notice about the sensors is available.

By double clicking the sensor indication on the screen, the user switch into Sensor View of that particular sensor.

Sensor View

The sensor view provides the user with relevant information regarding oil spill area and volume. The oil spill information is received onshore near real-time.

A delay of few minutes is introduced as the automatic identification module establishes its oil spill estimate on a sequence of measurements hereby delaying the decision for a few minutes.

The viewer screen is interactive and enables the user to select various view modes, provide zoom functionality and the ability to playback historical data.
