Oil Spill Detection
Miros’ oil spill detection system accurately detects oil spills, avoiding false alarms and enabling rapid response and recovery.
The Miros Oil Spill Detection system has a unique ability to interpret multiple indicators simultaneously, only triggering alarms when the “right” combination is identified. Indicators, which include wave height and behaviour, surface characteristics and drift, are collected and analysed using marine X-band radar, as well as infrared and daylight cameras. Miros OSD then processes the data and the appropriate signal is sent to the user interface.
Description
Every offshore installation must prepare itself for the unlikely event of an oil spill. Whilst early detection capability is vital, a low false alarm rate is also paramount since false alarms that initiate manual activities can be extremely costly. Nevertheless, dialling down the sensitivity of a system in order to avoid false alarms is not an option as this could lead to the delayed detection of genuine spills. The Miros Oil Spill Detection system has a unique ability to interpret multiple indicators simultaneously, only triggering alarms when the “right” combination is identified.
Miros OSD provides continuous monitoring of high-risk areas. The system automatically generates alarms based on oil spill detection and each individual slick is characterised according to area and drift. Thanks to its capacity to raise alarms promptly, the Miros Oil Spill Detection System is able to dedicate more time to the characterisation of spills and the initiation of appropriate responses.
Whether present on offshore installations, vessels or shore-based stations, the Miros oil spill detection system helps give authorities and operators the confidence that they are applying the best available technology to detect and control oil spills. Whilst at the same time reducing the risk (and potential cost) of false alarms.
With more than 200 Miros OSD™ systems delivered to oil companies, ship owners and coastal agencies around the world, Miros has established itself as a global leader in the provision of tools supporting oil spill response and surveillance operations.
