Abstract
Underwater Robotic Oil Spill Surveillance (UROSS) system provides constant and autonomous spill surveillance for subsea pipelines. M900 embedded Radio Frequency Identification tags and readers are used to identify pipeline section for surveillance. GY-521 gyrometer and XL-MaxSonar-WR1 ultrasound sensor are used for autonomous navigation. Spills are detected using a METS methane sensor. After spill detection, images of spill site are captured with a L3C-400 Micro Ultras-Miniature Color Camera and spill location is obtained using GPS. Spill Images and location are transmitted to a remote PC on the nearest off shore platform using an Xbee Pro 900HP wireless connection. An Ocean Signal rescueME Personal Beacon Locator transmits a 406 MHz distress signal via satellite to emergency services communicating the identification of a spill. Power analysis showed the system’s ability to remain submerged and to provide surveillance for 100 m sections of a subsea pipeline once every 24 hrs for a month, and can be increased to every hour for 51 months.
Highlights
Hundreds of crude oil spill incidents occur every year in oil producing countries and result in devastating national consequences to the environment, society, health, and economy [1]-[5]
Remote sensing involves the use of sensors, such as visible light sensors, infrared sensors, microwave sensors, radar sensors, and laser fluorosensors, aboard an airborne or Unmanned Aerial Vehicle (UAV) platform or a satellite-based platform to provide surveillance for crude oil spills over geographical regions [7]–[9]
This paper presents the use of underwater robotic systems, not to access and locate ongoing crude oil spills from subsea pipelines, but to provide constant surveillance for subsea crude oil pipelines so that spills are detected and contained within minutes of onset
Summary
Hundreds of crude oil spill incidents occur every year in oil producing countries and result in devastating national consequences to the environment, society, health, and economy [1]-[5]. Several methods have been employed for spill detection. In the Niger Delta of Nigeria, pipeline pressure monitoring and human surveillance units are used for spill detection. Remote sensing is the predominant method currently used for oil spill detection. Remote sensing involves the use of sensors, such as visible light sensors, infrared sensors, microwave sensors, radar sensors, and laser fluorosensors, aboard an airborne or Unmanned Aerial Vehicle (UAV) platform or a satellite-based platform to provide surveillance for crude oil spills over geographical regions [7]–[9]
