Manual System

Real-time monitoring and volume estimation

This real-time, onsite system provides information on the polluted area and estimates the oil spill volume within sensor range. The system consists of 2 modules where module 1 contains the basic functionality and module 2 contains additional functionality for cleanup operations.  

• Module 1 contains the first 3 screens and is intended for use on offshore structures or vessels, providing the user with a basic tool for real-time identification, tracking and quantification of oil spills within sensor range.

• Module 2 contains the basic features from module 1 but integrates spill data over time. The module is designed for oil spill recovery operations and provides the user with a comprehensive system that can collect and integrate data during Surveillance, Search and Recovery operations.

The OSIS onsite sensor system was designed to reflect various user scenarios. The resulting functionality and the available viewer screens are briefly described below.

Start-up View When starting the OSIS Viewer application, the user is introduced to a “welcome” screen. The user selects one of the sensor packs installed and enters the system by pressing “OK”.

Sensor View Sensor View is the default view and provides real-time information of the OSIS sensor measurements. Sensor modes and grid are selected using this screen picture and the contaminated area and volume is displayed intuitively together with other essential information. The latest hour of recordings is stored automatically and can be replayed.

Settings View Settings View is used to define the “clean water” area within sensor range and a number of essential parameters like wind, current and rain. By setting these parameters the Onsite Viewer is able to locate the contaminated area and calculate volume. The system reminds the user if and when new settings are needed.

Surveillance View Surveillance View illustrates the geographical area defined by the user. Information about offshore structures, marker buoys or the like can be visualized upon request. Current and historical position of the sensor is illustrated via a multi colored line also indicating the operational mode of the sensor. Surveillance view in the screen picture to the left is focused on the North European waters but any geographic area worldwide can be displayed.

Mission Planning The Mission Planning screen enables the user to save data over a longer period of time for damage assessment and operational planning during cleanup operations. The Mission Planning screen display swept area, polluted area and oil spill layer thickness as well as operational mode of the sensor.

Historical Data The historical data screen enables the user to playback data more than an hour old. This feature requires a Master Unit to be installed including OSD module in order to save the data created by the sensor. This feature is optional.

The manual system is specifically designed as a real-time system for onsite monitoring and control e.g. on offshore structures during tanker loadings at night or for cleanup operations installed on environmental vessels.
